RESUMO

Wunderlich syndrome is characterized by the presence of abdominal pain, hematuria, and hypovolemic shock. We report a rare case of a 25-year-old pregnant woman, who came to the emergency department due to the sudden onset of low back pain and diaphoresis. The patient, during medical evaluation, experienced an altered state of consciousness. Diagnosed with hypovolemic shock, she was admitted to the operating room, where examination of the abdominal cavity revealed a left retroperitoneal hematoma. Damage control surgery was performed, but given the postoperative clinical deterioration, computerized tomography angiography of the abdomen was performed, showing a mass-like lesion arising from the upper pole of the left kidney, consistent with Wunderlich syndrome. Left nephrectomy was the definitive treatment for the 10-cm renal angiomyolipoma. Since Wunderlich syndrome is a potentially lethal entity, CT is usually the preferred diagnostic approach, and supra-selective vascular embolization is the first-line treatment.

RESUMO

Fundamento: Los angiolipomas son tumores benignos que se presentan en adultos con una localización, preferentemente, en el espacio epidural posterior torácico. Objetivo: Presentar un caso que debutó con un traumatismo axial lumbosacro donde se evidenció una localización poco común de la lesión y sin relación con las estructuras del canal raquídeo. Presentación del caso: Hombre de 25 años que se cayó y debido a ello se le hizo un traumatismo directo en la región sacrococcígea con dolor y aumento de volumen regional, asociado a parestesias glúteas. Los estudios radiológicos evidenciaron una fractura del cóccix y la presencia de una lesión ubicada en las partes blandas, de aspecto redondeado, homogéneo, sólido, de poco más de 50 mm de diámetro. Se le realizó tratamiento quirúrgico que consistió en coccigectomía subperióstica y exéresis macroscópica de la masa. El estudio histológico concluyó el diagnóstico de un angiolipoma. Conclusiones: Los angiolipomas son tumores raros que tienen características radiológicas peculiares, requieren de alta sospecha clínico-imagenológica para indicar los estudios y el tratamiento. La exéresis total es recomendada para evitar la recurrencia y mejorar el pronóstico.

Background: Angiolipomas are benign tumors that appear in adults with special location in the posterior thoracic epidural position. Objective: To present a case that appeared with a lumbosacral axial trauma where a non-common lesion location was evidenced with no relation among the structures of the spinal canal. Case presentation: 25-year-old man who fell down, consequently suffered a painful direct trauma to the sacrococcygeal region and increased regional volume, associated with gluteal paresthesias. Radiological studies showed a fracture of the coccyx and presence of a lesion located in the soft tissues, with a rounded, homogeneous, solid aspect, a little more than 50 mm in diameter. Surgical treatment consisted of subperiosteal coccygectomy and macroscopic excision of the mass. Histological study concluded the diagnosis of an angiolipoma. Conclusions: Angiolipomas are rare tumors with peculiar radiological features, they require high clinical-imaging suspicion for studies and treatment. Total excision is recommended to avoid recurrence and improve prognosis.

RESUMO

This case report describes a benign breast tumor, more specifically, an angiolipoma, in a 17-year-old female patient who presented with a nodule in the left breast, painful to palpation. The nodule is at an atypical breast site and has few records in the literature, which were considered in this description that aims at identifying the main histological, ultrasound, mammographic and immunohistochemical characteristics of breast angiolipoma; besides informing other professionals about the possible angiolipoma diagnosis when considering a benign breast tumor, despite its rare occurrence.

RESUMO

Angiomyolipomas (AMLs) are benign tumors consisting of smooth muscle-like cells, adipocyte-like cells, and epithelioid cells. They are usually renal in origin, and extrarenal AMLs are rare. Cutaneous AMLs are even more rare. We present a case of 65 year old female, with no underlying genetic condition, who developed bilateral facial cutaneous AMLs. To the best of our knowledge, this is the first case in the literature. In addition, we investigate and suggest a correlation between human immunodeficiency virus and AMLs.

RESUMO

Laryngeal angiolipoma is a benign and rare tumor at this level. It is a type of unique lipoma, which is located in aritenoepiglottic retraction, epiglottis, and postcricoid region, and it is usually diagnosed after surgical exeresis. It is usually silent until it reaches a large size, causing dysphagia as the most common symptom; so it should be part of the differential diagnosis of odynophagia. We present a case in a male patient of supraglottic angiolipoma as an unusual cause of odynophagia

El angiolipoma laríngeo es un tumor benigno e infrecuente a este nivel. Es un tipo de lipoma único, que se localiza en el repliegue aritenoepiglótico, la epiglotis y la región poscricoidea, y suele diagnosticarse tras su exéresis quirúrgica. Suele ser silente hasta que alcanza gran tamaño, ocasionado odinofagia como síntoma más frecuente; de ahí que deba formar parte del diagnóstico diferencial de la odinofagia. Presentamos un caso en un paciente varón de angiolipoma supraglótico, como causa inusual de odinofagia

RESUMO

BACKGROUND: Angiolipomas are benign tumors most commonly found in the thoracic spine. They are composed of mature adipocytes and abnormal vascular elements that usually present with a slowly progressive course of neurological deterioration. CASE DESCRIPTION: A 35-year-old female, with a prior history of back pain, acutely developed paraparesis. When the thoracic magnetic resonance imaging (MRI) revealed a dorsal epidural mass at the T3-T5 level, she underwent a laminectomy for gross total excision of the lesion that proved to be an angiolipoma. On the second postoperative day, the patient was again able to ambulate. CONCLUSION: The angiolipomas of spine are rare causes of spinal cord compression, and those presenting with acute neurological deficits should be immediately treated.

RESUMO

El síndrome de Klippel-Feil es una malformación congénita de la charnela cráneo-cervical compleja que involucra vértebras y visceras, caracterizada por la tríada clásica de cuello corto, limitación de movimientos de la cabeza por la fusión de vértebras cervicales e implantación baja del cabello en la región occipital. Se presenta por falla de segmentación en el esqueleto axial del embrión. Su incidencia se estima en 1/40 000-42 000nacimientos y predomina en el sexo femenino. El objetivo del presente trabajo es describir el cuadro clínico de un paciente con síndrome de Klippel-Feil y múltiples malformaciones asociadas, entre ellas, fístula traqueoesofágica, pulgar bífido y lipomas/angiolipomas intracraneales, las cuales, hasta ahora, no han sido descritas en el síndrome, por lo que se considera un hallazgo excepcional.

The Klippel-Feil syndrome is a congenital malformation of the skull flap involving complex cervical vertebrae and organs, characterized by a classic triad: short neck, limitation of movement of the head due to cervical spine fusion and low hairline in occipital region. It results from an error in the axial skeleton segmentation of the embryo; its incidence is estimated at 1/40,000-42,000 births and predominates in females. The aim of this paper is to describe the clinical picture of a patient with Klippel-Feil syndrome and multiple malformations, including tracheoesophageal fistula, bifid thumb and intracranial lipomas/angiolipomas,that have not been previously described in the syndrome, so it is considered an exceptional finding.

RESUMO

Los lipomas intraóseos son considerados como los tumores óseos primarios benignos más raros por su muy poca frecuencia. Su incidencia es menor del 1 por 1.000 entre los tumores primarios y para 2002 se habían publicado menos de 100 casos a nivel mundial. El angiolipoma, es una variante histológica del lipoma aún menos frecuente, representando sólo del 5 al 17% de todos los lipomas intraóseos. Generalmente se trata de una lesión asintomática, un hallazgo radiológico en exámenes realizados por otras razones suele ser la forma de su diagnóstico. Sin embargo, algunos lipomas pueden ser sintomáticos. Presentamos el caso de paciente femenino de 36 años quien posterior a presentar dolor del tobillo derecho se diagnostica una lesión en el calcáneo, que posterior a su análisis anatomopatológico resultó ser un angiolipoma intraóseo. Presentamos su tratamiento con médula ósea autóloga y su evolución(AU)

Intraosseous lipomas are considered the rarest and a very infrequently benign primary bone tumors. Its incidence is less than 1 per 1,000 between primary tumors and by 2002 had published fewer than 100 cases worldwide. The angiolipoma, is a histological variant of lipoma even rarer, representing only 5 to 17% of all intraosseous lipomas. This is usually an asymptomatic lesion, radiological finding in tests performed for other reasons is usually the way to diagnosis. However, some may be symptomatic lipomas. We report the case of a female patient aged 36 who after presenting pain in the right calcaneus, which after pathologic analysis proved diagnosed intraosseous angiolipoma. We present treatment with autologous bone marrow and evolution(AU)

RESUMO

Spinal angiolipoma is an uncommon form of benign tumor. There are 142 reported cases and only one of acute paraplegia. We describe a case of a 39 year old male with acute spinal paraplegia angiolipoma in T4-T5 with surgical resolution three weeks after the onset of the neurological syndrome. Postoperative neurologic recovery was complete. The angiolipoma consists of mature fat cells and abnormal blood vessels. There are 2 types: non-infiltrating and infiltrating. Its clinical course is slow and progressive, it can be accelerated by vascular phenomena, intratumoral abscess, and pregnancy. There is just one report of spontaneous intratumoral hemorrhage and acute paraplegia, coinciding with our case. There is no consensus as to treatment, and release and complete resection are suggested, as it is a disease with good prognosis. Angiolipoma spinal epidural is a rare form of benign tumor, and the treatment of this pathology continues to be release and resection of the tumor, with a favorable prognosis, despite the delay in surgery, as in the case reported. Intratumoral bleeding should be considered a cause of acute spinal compression syndrome, as ocurred in our patient.

O angiolipoma espinhal é um tumor benigno incomum. Há 142 casos notificados, com apenas um de paraplegia aguda. Descrevemos o caso de um paciente de 39 anos com paraplegia aguda decorrente de angiolipoma espinal em T4-T5 com resolução cirúrgica três semanas após o início da síndrome neurológica. A recuperação neurológica pós-operatória foi completa. O angiolipoma consiste em células adiposas maduras e vasos sanguíneos anormais. Existem dois tipos: os não infiltrantes e os infiltrantes. Seu curso clínico é lento e progressivo, e pode ser acelerado por fenômenos vasculares, abcessos intratumorais e gravidez. Há somente um relato de hemorragia intratumoral espontânea e paraplegia aguda, coincidindo com o nosso caso. Não há consenso quanto ao tratamento, sugerindo-se a liberação e ressecção completa por ser uma doença de bom prognóstico. O angiolipoma espinal epidural é um tumor benigno incomum e o tratamento dessa patologia continua a ser a liberação e ressecção do tumor, que apresenta prognóstico favorável, apesar da demora da cirurgia, como no caso relatado. A hemorragia intratumoral deve ser considerada como causa da síndrome de compressão espinal aguda, como ocorreu com nosso paciente.

RESUMO

Intussuscepção intestinal é rara em adultos. Angiolipomas são causas incomuns da doença. Manifestações clínicas inespecíficas e acurácia limitada dos exames de imagem disponíveis dificultam o diagnóstico pré-operatório. A confirmação de intussuscepção é baseada em achados cirúrgicos. Ressecção intestinal é mandatória quando o cólon é acometido devido ao alto risco de malignidade. Relatamos um caso de intussuscepção colônica em um adulto jovem, secundária à angiolipoma.

Intestinal intussusception is rare in adults. Angiolipomas are uncommon causes of disease. Nonspecific clinical manifestations and limited accuracy of imaging available hinder the preoperative diagnosis. Confirmation of intussusception is based on surgical findings. Bowel resection is mandatory when the colon is affected due to the high risk of malignancy. We report a case of colonic intussusception in a young adult, secondary to angiolipoma.

RESUMO

Angiolipomas are benign lesions that are frequently found in subcutaneous cellular tissue, but are rarely located in the gastrointestinal tract. Here we discuss a case of colonic angiolipoma that presented as a mass near the hepatic flexure, occupying approximately 90% of the colonic lumen. The diagnosis was made by endoscopy and computed tomography. The mass was resected successfully and diagnosis was confirmed by histological studies and immunohistochemical tests.
