Glioblastomas multiformes (GBMs), are the most common primary malignant tumors of Central Nervous System. Frequently located in supratentorial topography, infratentorial location is rare, around 0-3.4% GBMs.   The diagnosis these uncommon adults, few cases have been reported, being even more infrequent elderly patients . typical clinical presentation a rapidly growing posterior fossa lesio...

Objectives: The characteristics of 144 Iraqi children with primary CNS tumors were reviewed to identify median age at presentation, the disease distribution in terms gender, main presenting symptoms, most common grade and histological subtypes, predominant subsites which central nervous system malignancies arise from, according WHO 2016 classification. Patients methods: Medical records used col...

Acute obstructive hydrocephalus due to infratentorial extra-axial fluid collection (EAFC) is an extremely rare complication of foramen magnum decompression (FMD) and durotomy for Chiari malformation type I. Presence of infratentorial  EAFC invariably causes obstruction at the level of the fourth ventricle or aqueduct of Silvius, thereby indicating its definitive role in hydrocephalus. Pathogene...

Complications were examined in a single surgeon's series of 207 consecutive adult patients undergoing first craniotomy for intra-axial brain tumour. The study group consisted of 114 gliomas, 74 metastatic tumours and 19 miscellaneous lesions. There were 25 infratentorial tumours and 182 supratentorial tumours (39 deep and 143 superficial). The total number of patients sustaining complications w...

Colloid cysts are relatively rare benign intracranial lesions preferentially located within the third ventricle. There are only a few reports in which they have been found to be ectopic, such as in the fourth ventricle. A young female presented on with spontaneous non-traumatic cerebrospinal fluid (CSF) rhinorrhoea for three months which was positional in nature, relieved temporarily by neck fl...

Introduction Movement disorders occur in 2–3% of patients with AIDS and are mostly caused by toxoplasmosis abscesses [1] . However, other rare etiologies such as progressive multifocal leukoencephalopathy (PML) or human immunodefi ciency virus (HIV)-associated dementia have been described [2, 3] . The diagnosis of PML is supported by typical MRI fi ndings and the detection of JC virus (JCV) DNA...

Phenylketonuria is a treatable inborn error of amino acid metabolism caused by deficiency of the enzyme phenylalanine hydroxylase, responsible for converting phenylalanine to tyrosine. We report a 10-month-old boy with psychomotor regression and infantile spasms. He was diagnosed with classic phenylketonuria and West syndrome. Treatment was initiated with phenylalanine-restricted diet and vigab...

Large or giant intracranial aneurysms can simulate brain tumors clinically and radiologically by virtue of their progressive mass effect. Unlike aneurysms from alternative locations, those arising from the distal posterior inferior cerebellar artery (PICA) are uncommon. We report a patient who experienced progressive hemiparesis with magnetic resonance imaging findings suggestive of an infraten...
