The compromising of the spinal canal by cysticercus is considered infrequent, varying from 16 to 20% in relation to the brain involvement. In the spinal canal the cysticercus predominantly places in the subarachnoid space. Clinical signs in spinal cysticercosis can be caused by direct compression of the spinal cord/roots by cysticerci and by local or at(More)
Temporal lobe epilepsy (TLE) is the most common form of partial epilepsy and affects 40% of the patients. Seizures arising from the mesial temporal lobe structures (i.e., amygdala and hippocampus) are common, whereas neocortical seizures are rare. In recent years, many studies aimed to identify the pattern of gene expression of neurotransmitters involved in(More)
Cysticercosis is the most frequent parasitosis of the nervous system and nowadays it is widespread through the world. Despite the development of anticysticercal drugs (praziquantel and albendazole), their efficacy is more marked in cases with parenchymal active cysts and they do not prevent complications such as hydrocephalus. Thus, many patients with(More)
Four cases of isolated fourth ventricle in neurocysticerocosis are reported (three after ventriculoperitoneal shunting, and one after hydrocephalus without shunting). Diagnosis was made based on computed tomography (CT) and/or CT cisternogram/ventriculogram. Three patients underwent fourth ventricle drainage (two died and the third remains well). The fourth(More)
Two cases of intramedullary paracoccidioidomycosis are reported. Paracoccidioidomycosis is a systemic disease that involves the buccopharyngeal mucosa, lungs lymph nodes and viscera and infrequently the central nervous system. Localization in the spinal cord is rare. Case 1: a 55-year old male admitted with crural pararesis, tactile/painful hypesthesia and(More)
The ultrasonography (Mode B--Real Time) experience was analyzed to evaluate neurological diseases in children during their first year of life. Forty-two examination were accomplished in twenty-eight children with the following diagnosis: hydrocephalus (22), normal (15), subdural hygroma (3), intracranial cyst and hydrocephalus (1), giant encephalocele (1).(More)
Multiple intracranial lesions observed in the computerized tomography ever cause worry due to the possibility of neoplastic etiology, although granulomatous diseases (parasitic or not) and vascular diseases can produce this type of lesions. Five patients with clinical picture that suggested expansive intracranial masses and that had multiple lesions in the(More)
The clinical course of patients with subarachnoid hemorrhage (SAH) due to rupture of cerebral aneurysm admitted during the last five years is analysed: 157 patients were treated by direct surgical approach of the aneurysm, 58 localized in the anterior communicating artery (ACoA), 48 in the internal carotid artery (ICA), 43 in the middle cerebral artery(More)
The authors reviewed the alterations observed on computerized tomography (CT) examinations of 16 patients with increased intracranial pressure and obstructive hydrocephalus due to cerebral cysticercosis. Plain radiograms of the skull were available in all cases and Dimer-X ventriculography in 12 cases. In 7 cases there were radiologic signs of increased(More)
Hemangioblastomas of the central nervous system (CNS) are low-grade highly vascularized tumors that may be sporadic or associated with Von Hippel-Lindau disease. Extradural hemangioblastomas are uncommon and those located extra and intradurally are even rarer. This study uses an illustrative case and literature review to discuss the difficulties to consider(More)
