Lipomatous extra-axial lesions in the Sylvian fissure are a rare entity. Their identification, however, is usually simple if a systematic radiological approach is adopted. The best line of management for these lesions is still a matter of controversy and fraught with complications. We present a case of a Sylvian fissure lipoma referred to our neurosurgery services with symptomatic seizures and ...

Local recurrence of craniopharyngiomas after apparently complete resection occurs frequently. Ectopic recurrence remote from the original site has been reported in 18 adult patients. The interval between the original diagnosis and the time of recurrence varies widely in these reports (1-26 years). We report a case of an ectopic recurrence in the sylvian fissure of an adamantinomatous type crani...

A total of 29 human cadaver brains were examined for asymmetries of the left and right Sylvian fissure, Heschl's gyri, and planum temporale. The mean lengths of these structures were all significantly greater on the left side than on the right. There was considerable morphologic variability in these structures as evidenced by the number of Heschl's gyri that ranged from one to three per hemisph...

OBJECTIVE To investigate somesthetic functions of the perisylvian cortex. METHODS Somatosensory evoked magnetic fields (SEFs) and somatosensory evoked potentials (SEPs) of the perisylvian cortex were recorded directly from subdural electrodes in a patient with a left frontal brain tumour. RESULTS The most prominent SEP components after electrical stimulation of the right and left hands and ...

Computed tomography of the brain was performed in thirty schizophrenic patients in the age group of 19-45 years and thirty controls matched for age and sex The size of lateral ventricles, the width of the third ventricle and the sylvian fissure were measured in the CT scans. On group comparison, we found that the size of lateral ventricles expressed as ventricular brain ratio, and the width of ...

Homologous neural networks seem to exist in the human left and right hemispheres tightly linking cortical regions straddling the sylvian fissure. White matter fiber bundles connect the inferior parietal lobule with the ventrolateral frontal cortex, ventrolateral frontal cortex with superior/middle temporal cortex, and superior/middle temporal cortex with the inferior parietal lobule. It is argu...
