RESUMEN
Omental torsion is a medical condition characterized by the twisting of the omentum along its longitudinal axis, which leads to compromised blood flow. This condition is rarely diagnosed before surgery and can present symptoms similar to other causes of acute surgical abdomen. This report details a case of primary omental torsion initially suspected to be acute appendicitis. The patient was admitted to the hospital with symptoms of lower right quadrant abdominal pain and mild fever. Computed tomography imaging revealed a twisted mass of fatty tissue with surrounding fat stranding changes, but no signs of appendicitis were found, indicating omental torsion. The patient underwent surgery to remove the twisted and necrotic omentum, leading to an improvement in symptoms. This case highlights the challenges in diagnosis and the crucial role of computed tomography imaging in managing this rare condition.
RESUMEN
An 8-year-old female domestic shorthair, presenting for a 3-day history of lethargy and hyporexia, was obtunded, dehydrated, tachypneic, and had abdominal distension on physical exam with no vaginal discharge or pyrexia. Abdominal radiographs revealed a large, ovoid soft tissue mass and a tortuous, tubular soft tissue structure in the abdomen. Abdominal ultrasound revealed a severely fluid-distended uterus with a left uterine torsion, which was demonstrated by a "whirl sign." Emergency ovariohysterectomy surgically confirmed a 360° torsion of the left uterine horn with a fluid-distended right uterine horn. Histopathology confirmed a diagnosis of pyometra, and the cat recovered uneventfully.
RESUMEN
Key Clinical Message: A whirl sign on contrast-enhanced abdominal CT scan is indicative of intestine twisted around the mesenteric vessels, and is observed in cases of strangulated obstruction, signaling compromised intestinal circulation. In cases of intestinal volvulus, surgery is necessary to untwist the affected bowel, and resection is necessary if necrosis is present. Abstract: A 31-year-old Japanese man presented with acute lower abdominal pain and vomiting. Contrast-enhanced abdominal computed tomography (CT) revealed a 1440-degree clockwise torsion of superior mesenteric artery and a whirl sign. Intestinal volvulus in adulthood with a background of malrotation is extremely rare. Contrast-enhanced CT is effective for diagnosis.
RESUMEN
A 5-year-old female spayed Dogue de Bordeaux was referred for concerns of an abdominal mass and peritoneal effusion. Abdominal radiographs identified a mid-ventral abdominal soft tissue opaque mass containing a radiopaque marker consistent with a gossypiboma. Contrast-enhanced abdominal CT identified two whirl signs associated with the abdominal gossypiboma. Exploratory laparotomy confirmed an omental torsion with encapsulated gossypiboma and concurrent incidental torsion of the remnant of the right broad ligament. Based on a literature review, omental torsions are an unreported complication of gossypibomas in canids.

Jejunoileal bypass (JIB) was an early bariatric procedure that involved bypassing most of the small bowel resulting in malabsorption and weight loss. Due to serious complications associated with the procedure, JIB was largely discontinued by the mid-1980s. We report the case of a 77-year-old woman with a history of JIB 31 years earlier. In 2022, she was hospitalized for acute abdominal pain. A computed tomography (CT) scan revealed a suspicion of internal hernia (IH) with a typical swirl sign. Due to the quick relief of symptoms an emergency surgery was not considered at the time. Nevertheless, a subsequent operation revealed a large mesenteric defect, adhesions and 100 cm of effective small bowel left. Although the procedure is no longer performed, some patients with JIB are still alive and develop late complications. To our knowledge, this is the first case report describing an IH in a patient who has undergone JIB.
RESUMEN
We present a case of a 22-year-old male presenting in the emergency room with colicky abdominal pain, vomiting, and abdominal distension for which an early computed tomography scan was done and diagnosed as cecal volvulus. Following diagnosis case was managed promptly by laparotomy with right hemicolectomy and primary anastomosis.
RESUMEN
A 1.5-year-old male neutered, 5 kg, Dachshund was referred for anorexia and vomiting for several days' duration. Radiographs revealed concern for a small intestinal obstruction. Ultrasonography revealed a severely distended segment of jejunum containing echogenic fluid that abruptly narrowed, twisted, and transitioned into normal jejunum, along with the presence of a distinct "whirl sign" that resulted from the intestinal segments twisting around themselves. This, in addition to the absence of flow on power Doppler interrogation, was compatible with a focal jejunal torsion-volvulus. The torsion-volvulus was surgically confirmed, a resection and anastomosis was performed, and the dog recovered uneventfully.

Intussusception, or telescoping of the bowel, is a rare condition in the adult population that can lead to serious complications, such as obstruction or ischemia. Most cases of intussusception are idiopathic and present with a pathognomonic "target sign" on imaging. Rarely, in adults, intussusceptions can be found with lead points, some of which may be neoplastic. Treatments for intussusception include air enemas or surgical intervention if enemas are unsuccessful in resolving the telescoped bowel. This case report discusses an atypical presentation of intussusception in an adult female with a "whirlpool sign" on imaging rather than the typical "target sign." She was found to have incorporation of mesenteric fat into telescoping bowel causing edema and partial bowel obstruction. The affected bowel was removed laparoscopically, and an end-to-end anastomosis was formed. Pathology of the resected bowel revealed a non-immunoreactive inflammatory myofibroblastic neoplasm as the lead point. Most inflammatory myofibroblastic tumors stain positive for desmin, smooth muscle actin, and anaplastic lymphoma kinase (ALK), whereas this patient was non-immunoreactive. The patient tolerated surgery well and is now pain-free with normal gastrointestinal function. This case report hopes to heighten awareness of atypical presentations of intussusceptions, the use of imaging to help aid in uncertain diagnoses, and the appropriate surgical treatment for symptomatic patients.
RESUMEN
The clinical presentation of a wandering spleen is characterized mainly by unspecific acute symptoms, ranging from diffuse abdominal pain to left upper/lower quadrant and referred shoulder pain to asymptomatic. This has challenged accelerated medical care and impeded the acquisition of confirmatory diagnosis; therefore, increasing morbidity and mortality risks. Splenectomy is an established operative procedure for a wandering spleen. However, there has not been enough literature emphasizing the clinical history of congenital malformations and surgical corrections as inferential tools for facilitating a decisive and informed procedure. The case presented is of a 22-year-old female who reported to the emergency department with a five-day persistent left upper quadrant and left lower quadrant (LLQ) abdominal pain, associated with nausea. According to the medical history, the patient had a significant history of vertebral defects, anal atresia, cardiac anomalies, tracheoesophageal fistula, renal anomalies, and limb abnormalities (VACTERL) associated with congenital anomalies. By the age of eight years, the patient had undergone multiple surgical interventions, including tetralogy of Fallot repair, an imperforate anal repair with rectal pull-through, Malone antegrade continence enema (MACE), and bowel vaginoplasty. Computed tomography imaging of the abdomen revealed evidence of a wandering spleen in the LLQ with associated torsion of the splenic vasculature (whirl sign). Intra-operatively, appendicostomy was identified extending from the cecum in a near mid-line position, to the umbilicus, and carefully incised distally, preventing injury to the appendicostomy. The spleen was identified in the pelvis, and the individual vessels were clamped, divided, and ligated. Blood loss was minimal with no post-operative complications. This rare case report adds valuable teaching points about the treatment of wandering spleen in individuals with VACTERL anomalies.
RESUMEN
@#Cecal volvulus is a rare cause of intestinal obstruction caused by axial twisting of the cecum that occurs in 1–1.5 % of all intestinal obstruction, with an incidence of 2.8–7.1 cases per million annually. Cecal volvulus is potentially life-threatening without prompt surgical intervention. A 57-year-old woman presented with severe abdominal pain and distention. Laboratory examinations revealed normal white blood cell count with neutrophilic predominance. Diagnosis of acute cecal volvulus was made from a “whirl sign” on abdominal computed tomography. An exploratory laparotomy confirmed the diagnosis of cecal volvulus and a segmental ileocolic resection with primary anastomosis was carried out. The patient was discharged improved and returned to her normal activities of daily living.
RESUMEN
Caecal volvulus (CV) is a rare cause of intestinal obstruction, defined by an axial torsion of the caecum, ascending colon, and terminal ileum around the mesenteric vascular pedicles, leading to ischemia and bowel necrosis. A 20-year-old woman, with no significant medical history, was admitted for generalized abdominal pain evolving for three days, along with constipation and abdominal distension, but with no vomiting. Physical examination showed a generalized abdominal tenderness with no rigidity or rebound tenderness, associated with abdominal distension and tympanic upon percussion. Laboratory findings were within normal limits. An abdominal computed tomography scan revealed distension of a loop of the large bowel with its long axis extending from the right lower quadrant to the epigastrium or left upper quadrant. Colonic haustral pattern was absent. An abdominal computed tomography scan showed a rounded focal collection of air-distended bowel with haustral creases in the upper left quadrant. In addition, spiraled loops of the collapsed cecum (giving a whirl sign) were noted, along with low-attenuating fatty mesentery from the twisted bowel. The patient underwent an emergency laparotomy and caecectomy using GEA 80 charges. The patient had no complaints post-operation. CV is a rare cause of bowel obstruction, mainly caused by an exceedingly mobile caecum. Despite its rareness, CV represents the second most common cause of large bowel volvulus, behind sigmoid volvulus. For acute obstruction by CV, it is hard to differentiate it clinically from obstruction of the small bowel; therefore, radiological exams are needed. Surgery is the gold standard treatment for CV. We report a rare case of CV to highlight the rarity of this pathology, specify its diagnostic and therapeutic means, and its clinical and biological evolution.

Teaching Point: The coffee bean sign, the whirl sign, and the bird's beak sign are the key findings on abdominal CT of cecal volvulus.
RESUMEN
An 8-year-old mixed breed dog, was referred for lethargy, abdominal discomfort, hematemesis, and melena. Abdominal ultrasound revealed mineralization of the "right splenic vein" with collateral spiraling and a suspected splenic duplication. Computed tomography confirmed the duplication along with torsion of the splenic pedicle. Exploratory laparotomy confirmed the splenic torsion associated with congestion of the gastrointestinal vessels, indicative of a chronic onset of secondary regional splenic vein hypertension.

Colonic torsion is a life-threatening condition that results in colonic ischemia, necrosis, perforation, sepsis, and eventual death. The aim of this multicenter, retrospective case series study was to describe the CT findings in dogs with surgically confirmed colonic torsion. Medical records were searched for dogs with surgically confirmed colonic torsion following abdominal CT. Five dogs met the inclusion criteria. Three had a history of chronic intermittent diarrhea prior to presentation. Two dogs presented with acute vomiting, diarrhea, and abdominal pain and one dog presented with acute vomiting and lethargy. Computed tomographic findings in all dogs with surgically confirmed colonic torsion include: "whirl sign," displacement and distension of the cecum and colon, focal narrowing of the colon, and distension of the mesenteric vasculature in all dogs (5/5); streaky peritoneal fat and peritoneal effusion (4/5), pneumatosis coli (2/5), small intestinal distension (2/5), portal vein thrombosis (1/5), and reduced colonic wall contrast enhancement (1/5). In all dogs (5/5), the torsion site was the descending colon and demonstrated an anticlockwise rotation. At surgery, three of the five dogs had a partial colonic torsion with hyperemia at the site of obstruction and two of the five dogs had a complete torsion with marked necrosis of the colonic wall. Displacement of the colon and cecum, segmental distension and focal narrowing of the colon, the presence of a "whirl sign" and distension of the mesenteric vasculature are CT findings highly suggestive of colonic torsion.

BACKGROUND: Caecum volvulus (CV) is defined as an axial twisting that causes an inversion position of the caecum, ascending colon and terminal ileum. This anatomical finding is responsible for some clinical features. Obstruction and strangulation are the most important and life-threatening. CASE PRESENTATION: We are presenting a 50 years old woman presented to the hospital with sudden acute severe abdominal pain and distension of about 24 hours associated with vomiting and no flatus. CONCLUSION: Mortality in patients with CV can be kept near 10%-12% if operative intervention is accomplished before caecum strangulation. Once the cecum has become gangrenous, a death rate of 30 to 40% can be expected. Tailored made surgery on patients status is the strategy.
RESUMEN
Adhesive closed-loop small bowel obstruction can lead to volvulus and ischemia with risk of necrosis. The vital prognosis and bowel viability are highly dependent on rapid management. The physical examination is often insufficient to establish the diagnosis and computed tomography is ordered. The whirl sign provides the best imaging evidence of volvulus and can be sufficient to establish the indication for surgery.

An 11-year-old male German Shepherd dog presented for inappetence and weight loss. Physical examination and initial bloodwork revealed palpable abdominal masses, mild non-regenerative anemia, and thrombocytopenia. Survey radiography and abdominal ultrasonography confirmed the presence of bilateral abdominal masses and lymphadenopathy. Contrast-enhanced computed tomography (CT) was performed in order to further investigate the origin of the intraabdominal masses, confirming two enlarged cryptorchid testes, one of which had an associated CT "whirl sign." Histopathology of the testes and lymph nodes revealed bilateral malignant Sertoli cell tumors and seminomas with lymph node metastasis of both neoplasms. The purpose of this case report is to discuss the benefits of CT in the diagnosis of cryptorchid testes and describe an additional organ that may display CT "whirl sign."
RESUMEN
We present the case of a 38-year-old male with an atraumatic splenic rupture, hemoperitoneum, and ileal volvulus following acute cocaine intoxication. Computed tomography showed a "whirl sign", a subcapsular splenic hematoma with suspected peripheral laceration, and diffuse hemoperitoneum. At laparotomy, the spleen was confirmed to be the source of bleeding and was removed. A nonreducible volvulus was found at the distal ileum, and this segment of small bowel was removed. The patient had an uneventful postoperative recovery.
