RESUMEN

BACKGROUND: The foci of distant metastasis from extramammary Paget's disease (EMPD) are the lung, liver, truncal bones, vertebrae, and brain. However, skull metastases have not been reported. OBSERVATIONS: The authors treated a patient with calvarial and skull base metastases from EMPD who had undergone wide local resection of EMPD 8 years before, and they report his clinical course. LESSONS: Because EMPD with distant metastasis is fatal, it should be recognized that EMPD can metastasize to the skull even when it seemed to be in remission for several years.

RESUMEN

BACKGROUND: With the increasing trend of metabolic syndrome (MetS) and atherothrombotic stroke (which can manifest as stroke lesion multiplicity), studies on the association between MetS and the clinical aspects of atherothrombotic stroke are of great interest. The present study aimed to investigate the association between MetS and multiple atherothrombotic strokes in patients with intracranial atherothrombotic stroke. METHODS: A retrospective study based on medical charts was conducted among patients (n = 202: 137 men/65 women) who were symptomatically admitted to the hospital with the first-ever atherothrombotic stroke. For the occurrence of multiple lesions of stroke, odds ratio [OR: 95% confidence interval (CI)] of MetS or its respective components was calculated using logistic regression models. RESULTS: Fifty-one percent of the men and 38% of women with stroke presented multiple regions. MetS was a significant factor that was associated with an increased risk of multiple regions in women [OR 4.3 (95% CI 1.4-13.5)], but not in men. According to the components of MetS, dyslipidemia was a significant factor that was positively associated with multiple regions in both men [OR 2.0 (95% CI 1.1-3.7)] and women [OR 3.2 (95% CI 1.1-9.1)]. CONCLUSION: MetS may be pathophysiologically associated with intracranial atherothrombotic stroke multiplicity in women in particular. Future studies are warranted to confirm the findings.

RESUMEN

Chondromas originating from the sella turcica are rare, and the most common initial symptoms are headache and visual disturbance. We describe a case of sellar chondroma with endocrine impairment as an initial manifestation that completely resolved after surgery. A 40-year-old Japanese woman with amenorrhea and galactorrhea for the last 2 years was referred to our department of neurosurgery for the evaluation of high prolactin levels and a tumor in the sella turcica. A biochemical assessment indicated endocrine dysfunction. Magnetic resonance imaging and computed tomography indicated a tumor in the sella turcica. The patient's presentation favored the preoperative diagnosis of pituitary adenoma or Rathke's cleft cyst. However, because calcification was detected, other types of tumors, such as craniopharyngioma, meningioma, and chordoma, were also considered. Endoscopic transsphenoidal surgery was performed, and the possibility of a bony tumor was recognized. Finally, the tumor was completely removed, and the histopathological findings confirmed chondroma. The postoperative course was uneventful, and endocrine function improved. Five years after surgery, the patient is doing well without pituitary insufficiency, pituitary hormone medications, or signs of tumor recurrence. In cases of sellar chondroma, endocrine dysfunction sometimes precedes other symptoms, such as headache and visual disturbance. When examining a patient with an intrasellar tumor harboring calcification, clinicians must consider the possibility of sellar chondroma. Furthermore, to the best of our knowledge, this case is the first of sellar chondroma treated with endoscopic surgery to be reported.

RESUMEN

The successful obliteration of torcular dural arteriovenous fistula (DAVF) with a diffuse shunt in the affected sinus may require complex treatment strategies. Therapeutic goals include the preservation of normal venous drainage and complete obliteration of shunt flow. The authors report the case of a torcular DAVF. The treatment of this type of AVF may require a combined approach with transarterial and transvenous embolization, open surgery, or radiosurgery and is associated with many problems. Stent placement and angioplasty in the affected sinus result in compression of the fistulous dural wall of the sinus and decrease shunt flow. In cases in which there is a diffuse shunt in the affected sinus and no evident shunt point, such as in AVFs involving venous pouches and parasinuses, sealing the fistula orifice with self-expandable stents and angioplasty (balloon inflation) is considered the best treatment option to preserve normal cerebral venous sinus drainage and obliterate shunt flow. In such cases, the authors recommend using one or more self-expandable and closed-cell stents and using angioplasty to avoid endoleakage into the gap between the stent graft and the vessel wall.

RESUMEN

BACKGROUND: Criteria to decide whether carotid endarterectomy (CEA) or carotid artery stenting (CAS) is the best mode of therapy in a specific case of cervical carotid stenosis have not been established. Overall, recent randomized clinical trials have reported that the effect on the prevention of stroke is not significantly different between CEA and CAS. CEA is more appropriate than CAS for soft atherosclerotic plaques, since such soft plaques are associated with a high incidence of ischemic complications during CAS. Therefore identification of the plaque type with noninvasive preoperative examinations plays an important role for selecting the suitable surgical method, CEA or CAS. OBJECTIVE: The objective of this study was to evaluate the association among findings of carotid ultrasonography (carotid US), black blood magnetic resonance imaging (BB-MRI), and the histopathological findings of plaque specimens removed during CEA, and secondly to consider whether these diagnostic tools are useful to predict the characteristics of carotid plaques. METHOD: We investigated a total of 25 consecutive patients who underwent CEA from November 2008 to June 2010 at Kyoto Medical Center. We examined carotid plaque in 17 patients employing both carotid US and BB-MRI, 7 patients by carotid US, and 1 patient by BB-MRI. The plaque echogenicity was qualitatively assessed as low, intermediate, or high, and the MR signal intensity of the carotid plaque was classified as low or high compared with the intensity of the ipsilateral sternocleidomastoid muscle. The plaque specimens were macroscopically and pathophysiologically classified as soft or hard plaque. RESULTS: All low-echogenic plaques on carotid US were histologically soft plaques. The high-intensity plaques on T1-weighted imaging (T1WI) showed a tendency toward soft plaque. Thirteen of 14 plaques with high signal intensity on T1WI were morphologically soft. Eleven of 14 plaques with an intermediate echogenicity on carotid US were also morphologically soft. CONCLUSION: The findings of carotid ultrasonography and BB-MRI are closely associated with the CEA specimen's morphology. Ultrasonography alone is insufficient to diagnose the plaque type accurately in some patients. Employing both carotid US and BB-MRI is useful for evaluating the characteristics of carotid plaque.

RESUMEN

The indication for carotid endarterectomy (CEA) or carotid artery stenting (CAS) has not been established, although the beneficial effects of these surgical treatments for severe cervical carotid stenosis have been confirmed by clinical trial studies. We report our clinical results of CAS and CEA and suggest an appropriate treatment strategy, especially for high-risk patients. From January 2001 to December 2009, we treated 171 carotid lesions by CEA and 251 lesions by CAS. Stenosis was symptomatic in 68%, and the average stenotic rate was 83% in the CEA group. In the CAS group, stenosis was symptomatic in 62%, and the average stenotic rate was 65%. Stenosis was relieved in all cases after CEA or CAS. Surgical mortality with CEA and CAS was 0.6% (1/171) and 0.4% (1/251), respectively. Surgical morbidity by ischemic stroke with CEA and CAS was 2.9% (5/171) and 1.2% (3/251), respectively. Surgical morbidity was not increased in patients with medical risk factors. The long-term outcome after CAS was not inferior to that after CEA. In conclusion, carotid stenosis can be treated with comparably low morbidity and mortality rates using CEA or CAS even in high-risk patients when the method is appropriately selected considering the characteristics of the carotid stenosis.

RESUMEN

INTRODUCTION: We report the long-term results of surgery for carotid stenosis in our institute, and suggest a better treatment strategy for high-risk patients. MATERIALS AND METHODS: Our series of 352 carotid surgeries conducted between April 1998 and May 2007 were investigated. CEA comprised 134 (38%), whereas CAS comprised 218 (62%). In August 2007, we sent questionnaires to all patients, and analyzed responses up to May 2008. For patients undergoing regular follow-up, the data were gathered from the medical records. The questions were: (1) mRS at that time, (2) the cause of death if the patient was deceased, (3) newly diagnosed stroke, and (4) newly diagnosed coronary heart disease. RESULTS: The response rate was 68.8%. The average follow-up period was 31.2 months. The average differences in mRS pre- and postoperation were -0.33 and -0.48 in CEA and CAS, respectively. The mortality rate at >30days was 8.2% in CEA, and 5.0% in CAS. The leading cause of death was heart disease (31.8%). CONCLUSION: Our report suggests that CAS is not inferior to CEA, and both procedures can be managed safely if all characteristics of the carotid lesions are considered.

RESUMEN

A 19-year-old female was admitted to our hospital after severe head injury in a traffic accident. On admission, she had no spontaneous respiration, but did have heart beat with a blood pressure of 100/60 mmHg. Neurological examination demonstrated that the Glasgow Coma Scale score was 3 and her pupils were fixed and dilated. Computed tomography (CT) showed diffuse brain swelling with disappearance of the perimesencephalic cistern. Chest CT showed bilateral lung contusions. Mild hypothermia with a target temperature of 33 degrees C was immediately induced, and was continued for 28 days to control the persistent increase in intracranial pressure (ICP). Subsequently, she recovered, and 20 months after admission, could speak and walk with slight hemiparesis on the left. Prolonged mild hypothermia may be effective to control persistent increase in ICP due to diffuse brain swelling.

RESUMEN

A 30-year-old man presented with a 2-year history of intermittent headache. No neurological deficit was detected. Computed tomography (CT) and magnetic resonance imaging showed a tumor with a diameter of 2.5 cm in the left anterior skull base associated with bone scalloping on three-dimensional CT. Angiography showed a hypovascular tumor. Craniotomy demonstrated a tumor in the region of the left olfactory groove attached to the anterior part of the cribriform plate. The histological diagnosis was schwannoma. Schwannoma arising from near the olfactory groove is rare, with only 13 other cases reported. The precise origin of these tumors is not well understood, but the tumor in this case probably arose from the fila olfactoria, because the olfactory bulb was involved in the tumor, whereas the olfactory tract remained intact.
