Right-sided weakness, sepsis. Human immunodeficiency virus. There is a deep right superior frontal sulcus with thickening and irregularity of the cortex and focal enlargement of the underlying right lateral ventricle, which appears to communicate with the sulcus through a very narrow channel. There also appear to be prominent perivesicular spaces in this region. Otherwise, there is no evidence of intracranial hemorrhage, mass, or acute infarct. There is no abnormal intracranial enhancement. There is no midline shift or herniation. The major cerebral flow voids are intact. The orbits, skull, paranasal sinuses, and scalp soft tissues are grossly unremarkable.
1. No evidence of central nervous system lymphoma or toxoplasmosis. 2. Findings compatible with right frontal lobe schizencephaly.
