With adequate
Sylvian fissure dissection, it is effective to widely expose the insular cortex without damage to the frontal or temporal cortex.
The
sylvian fissure. The structures that have been measured most frequently in studies of language and reading impairment are the auditory structures on the superior surface of the temporal lobe -- Heschl's gyrus and the planum temporale.
Slight narrowing of cortical gyri on the vertex with enlarged
Sylvian fissure. (c) Baseline Axial T2-weighted sequences.
Post-contrast scans reveal meningeal enhancement along the
Sylvian fissures, interpeduncular, perimesencephalic cisterns, ependymal enhancement along bilateral ventricular linings and bilateral choroid plexus enhancement; TOF Angio reveals beaded appearance of bilateral MCA and PCA.
Abnormal
Sylvian fissure on prenatal cerebral imaging: Significance and correlation with neuropathological and postnatal data.
A pseudo-SAH is a brain CT finding that is seen as high attenuation areas (HDAs) along the basal cisterns, the
sylvian fissure, the tentorium cerebelli, or the cortical sulci in patients with severe brain edema, where no SAH is seen at autopsy or lumbar puncture [6].
Brain magnetic resonance imaging (MRI) demonstrated subacute hemorrhage in the left frontotemporal lobe with mild mass effect, and a nodular lesion near the
Sylvian fissure [Figure 1]a], yet contrast study showed no abnormal enhancement.
Splitting the
Sylvian fissure the frontal and temporal lobes could be separated.
