Retrospective study of 23 pathologically proven cases of central nervous system tuberculomas
Introduction: Extrapulmonary manifestations of tuberculosis involving the central nervous system (CNS) due to haematogenous spread are not a rare entity. It presents as meningitis or tuberculoma. Tuberculoma is a granulomatous inflammatory process mimicking a neoplasm radiologically, so usually a biopsy is performed
Cerebral Tuberculoma Mimicking High Grade Glial Tumor
Tuberculosis has been an important public health problem in both developing and develop nations. Tuberculosis of the central nervous system is rare. Tuberculosis meningitis and tuberculoma are the two most important manifestations of tuberculosis of the CNS. Intracranial tuberculomas may be solitary or multiple. Solitary tuberculomas may be indistinguishable from cranial abscess or primary brain tumor. It is necessary to rule out tuberculoma in patients with intracranial mass lesions. We present a case of tuberculoma mimicking a high grade glial tumor on magnetic resonance imaging and clinical presentation. A 30-year-old woman presented with one-month history of epilepsy. Cranial magnetic resonance imaging showed a left occipital peripheral ring-enhanced lesion with central necrosis. There was a strong suspicion of glial tumor. The lesion was totally excised with left occipital craniotomy. Histological examination of mass revealed a tuberculoma. The patient was treated with antituberculous chemotherapy
Primary cerebellopontine angle craniopharyngioma in a patient with Gardner syndrome
Craniopharyngiomas usually involve the sella and suprasellar space. Ectopic craniopharyngiomas have rarely been reported at the cerebellopontine angle (CPA). We report a rare primary craniopharyngioma of the CPA without extension into the sellar region. The lesion was initially detected by MRI during investigation of multiple scalp fibromas. Multiple osteomas of the skull and face were detected 2 years later, and colonic adenomatous polyposis was detected 4 years later; typical features of Gardner syndrome. This is the third report of a primary CPA craniopharyngioma in a patient with Gardner syndrome. (C) 2010 Elsevier Ltd. All rights reserved
Bilateral Lhermitte-Duclos disease
Lhermitte-Duclos disease (LDD) is a pathologic entity with
progrediating, diffuse hypertrophy chiefly of the stratum granulosum of
the cerebellum. Typically LDD is a unilateral lesion of the cerebellum
or in vermis. Here we report a case of LDD with bilateral lesions of
cerebellar hemispheres managed surgically. A 28-year-old woman
presented with one-year history of progressive headache, nausea,
vomiting, and blurred vision. Neurologic examination revealed a
bilateral mild papilledema, mild dysmetria, and dysdiadochokinesia. The
cerebellar lesions caused moderate mass effect in posterior fossa with
hydrocephalus, and Chiari type I malformation. We performed the
suboccipital-retrosigmoid approach, and removed completely the left
intracerebellar mass. Symptoms related to elevated intracranial
pressure disappeared in a short period postoperatively
Symmetric Dumbbell Ganglioneuroma of Bilateral C1 Roots With Intradural Extension Associated With Von Recklinghausen's Disease: A Case Presentation
Introduction: Ganglioneuromas are rare benign tumours arising most commonly from the sympathetic nervous system. They occasionally grow in a dumbbell fashion extending into the spinal canal extradurally. But, ganglioneuromas in association with von Recklinghausen's disease are rare
Removal of clival chordoma in an adolescent thorough combned pterional transsylvian and anterior temporal approach
Extensive and aggressive surgical removal is treatment of choice for patients who have chordomas of the cranial base. Well-developed microsurgical techniques, as well as good surgical judgment learned from experience are essential to avoid major morbidity. A 14-year-old female presented with progressive headaches and diplopia for three months. Cranial magnetic resonance imaging demonstrated a well-circumscribed mass in the clival region. The mass was totally excised via right combined pterional transsylvian and anterior temporal approach (+ orbitozygomatic osteotomy). The tumor was located extradurally. The resected tumor had the typical histological and immunohistochemical characteristics of chordoma. No radiation therapy or chemotherapy was administered
The Effect of Copper on Vasospastic Femoral Artery in Rats
AIM: The aim of this study was to investigate the effect of copper, which is the cofactor and regulator of the superoxide dysmutase enzyme, on preventing experimental peripheral vasospasm in rats through antioxidative mechanisms
Expression of Ki-67, p53 and vascular endothelial growth factor (VEGF) concomitantly in growth hormone-secreting pituitary adenomas; which one has a role in tumor behavior?
OBJECTIVE: In many pituitary tumor, immunohistochemical studies have been shown to be correlated with different aspects of tumor behavior. There is no study up to date in which markers of Ki-67, p53, VEGF were evaluated concomitantly in GH-secreting adenomas. This study aims to determine which marker has a major role in tumor behavior and whether these markers have a cut-off value to distinguish invasive adenoma from non-invasive pituitary adenoma
