hemangiopericytoma/seizures

First reported case of simultaneous occurrence of hemangiopericytomas(HCP) at multiple sites of craniospinal axis in a thirty four year male is presented. Patient presented with neck pain for 1 year, and one episode of simple partial seizure involving his left lower limb. He was diagnosed as having

UNASSIGNED Ectopic insulin-like growth factor (IGF)-2 production is a rare complication of an array of epithelial and mesenchymal tumors, and can clinically manifest as life-threatening hypoglycemia. UNASSIGNED A 49-year-old woman with 13-year history of metastatic hemangiopericytoma, previously

OBJECTIVE The purpose of this study was to analyse a series of patients harbouring an intracranial hemangiopericytoma (HPC) with respect to clinical presentation, treatment results and long-term follow-up outcomes. METHODS Clinical data were retrospectively obtained in a series of 12 patients who

To investigate the diagnosis, treatment and prognosis of solitary fibrous tumor (SFT)/ hemangiopericytoma (HPC) of central nervous system (CNS), we retrospectively reviewed records of 17 patients who were treated for CNS SFT/HPC at the Department of Neurosurgery, China-Japan Union Hospital of Jilin

BACKGROUND Intracranial meningeal hemangiopericytoma (HPC) represents a rare and aggressive intracranial neoplasm located along the dural sinuses. It constitutes less than 1 % of all intracranial tumors and approximately 2-4 % of all meningeal tumors. The authors present our institute's experience

Hemangiopericytoma (HPC) is a rare vascular tumor, which is thought to originate from pericytes. However, no direct evidence for the cell of origin has been found, and the mechanism of HPC tumorigenesis is poorly understood. Here we report that loss of the tumor suppressor gene Tsc2 in pericytes

Unpredicted sudden death arising from hemangiopericytoma with massive intracranial hemorrhage is quite rare. We encountered a patient with recurrent infratentorial hemangiopericytoma presenting as life-threatening massive intracerebral hemorrhage. A 43-year-old man who had undergone craniotomy for

BACKGROUND Intracranial chondroid tumors are infrequently seen in neurosurgical practice. These tumors usually arise from cartilaginous synchondroses at the base of the skull, but occasionally from the pluripotential mesenchymal cells of the meninges. We present here a case of classic low-grade

The patient was a 24-year-old male who was admitted to the Dept. of Neurosurgery of Miyazaki Medical College in April of 1982 with a history of generalized convulsive seizures. Neurological examination on admission revealed slight mental disturbance, bilateral marked papilloedema and homonymous

BACKGROUND In 1996, Hinchey and colleagues coined the term "Posterior reversible encephalopathy syndrome" (PRES) to describe a condition seen in patients with acute neurological symptoms and reversible subcortical vasogenic edema predominantly involving parieto-occipital areas demonstrated in brain

OBJECTIVE Capillary hemangiomas are benign tumors or tumorlike lesions that originate from blood vessels and have rarely been reported to develop in the brain or spinal cord. The authors summarize the clinical and histological features of capillary hemangiomas of the central nervous system

OBJECTIVE Although meningiomas are commonly found along the supratentorial convexity, the risk profile associated with this subset of lesions in the modern neurosurgical era is unknown. METHODS The authors retrospectively reviewed the clinical course of patients with supratentorial convexity
