BACKGROUND Astroblastoma is a rare glial tumor that occurs mainly in the cerebral hemispheres of young adults. Our purpose in writing this article is to report one case of astroblastoma located within the medulla and review the literature on this infrequent tumor. METHODS One case of astroblastoma was retrospectively reviewed. Presenting complaints,(More)
Central pontine myelinolysis (CPM) can be regarded as one of the demyelinating syndromes. First described by Adams et al. in 1959 in their chronic alcoholic patients, it has now been described in the malnourished, the chronically debilitated, the renal, the hepatic and the transplant patient among others. Pathologically, it is defined as a symmetric area of(More)
Metastatic cancer must be considered as a possibility for intrasellar masses. Newer treatment modalities, such as gamma knife radiosurgery needs to be explored for these lesions. Three cases of intrasellar metastatic lesions were retrospectively reviewed. Presenting complaints, radiographic studies, operative procedure, and histopathological confirmation(More)
Vasculitis or angiitis refers to a group of inflammatory disorders of the blood vessels that cause structural damage to the affected vessel, including thickening and weakening of the vessel wall, narrowing of its lumen, and, usually, vascular necrosis. Systemic vasculitis is classified according to the vessel size and histopathologic and clinical features.(More)
Papillary tumors of the pineal region (PTPR) are very rare. We describe the first report of a PTPR empirically managed with gamma knife radiosurgery. The patient was initially shunted and referred for empirical gamma knife radiosurgery. After initially showing some improvement, he had recurrence of tumor after 7 years. For recurrence he underwent a gross(More)
Choroid plexus papillomas (CPP) are histopathologically benign and rare central nervous system (CNS) neoplasms arising from the epithelium of the choroid plexus. The most common site of presentation of these lesions is in the fourth ventricle in adults and lateral ventricles in children. Third ventricular CPP are uncommon. In this study, we present a case(More)
A 26-year old man presented with a 3-month history of a progressively enlarging palpable parieto-occipital mass. A CT scan indicated the lesion arose from the dura with bony destruction. A stealth assisted craniotomy was performed with the provisional diagnosis of osteoblastic meningioma. Further histopathologic analysis of the intracranial mass was(More)
Central nervous system tuberculoma presenting as a solitary mass in an extrinsic location is rare. Due to the increase in incidence of tuberculosis in the western world, there is a corresponding increase in CNS tuberculosis. Cerebellopontine angle tumours are most commonly acoustic schwannomas or meningiomas. Radiosurgery as a primary modality of treatment(More)
BACKGROUND Pituitary carcinomas are rare and challenging clinical entities. Because of the paucity of cases, there is limited information in the literature on how best to diagnose and treat pituitary carcinomas. METHODS We review the literature and describe a woman who presented with an adrenocorticotropic hormone (ACTH)-secreting pituitary macroadenoma(More)
