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...

in the present study, variation among different bacterial strains was observed in the plaques of tobacco chewers (tc) as compared to those from normal persons (non tobacco chewers) (ntc). bacterial strain j1 (dominant in the plaques of ntc) did not initiate the process of adhesion (biofilm formation) until it appeared to have reached a required population density necessary for the production of...

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...

Complex posterior circulation aneurysms are formidable lesions with an abysmal natural history. Their management continues to present a challenge to both endovascular and open microsurgical approaches. Affording an expansive, combined supra- and infratentorial exposure, the petrosal approaches are well suited for these challenging lesions when located along the basilar trunk or at a low-lying b...

Intracranial pressure was raised by expansion of a supratentorial subdural ballon in anaesthetized baboons. Pressures were measured at several sites, both supratentorial and infratentorial, and cerebral blood flow was measured in each cerebral hemisphere separately. Pressures recorded from the right and left lateral ventricles corresponded closely throughout. Highly significant correlations wer...

Multiple simultaneous intracerebral hemorrhages (ICH) are uncommon. We report the case of an 80-year-old woman with previous diagnosis of normal pressure hydrocephalus and who was brought to our hospital with altered mental status and urinary incontinence. Medical history of hypertension, hematological disorders or severe head trauma was absent. Platelet count and coagulation profile were unrem...
