HIV with bacterial meningitis, numerous other infections. There is no evidence of intracranial hemorrhage, mass, or acute infarct. There is a faint patchy focus of T2 hyperintensity in the pons. The brain parenchyma otherwise appears unremarkable. There is no abnormal intracranial enhancement. The ventricles and basal cisterns are normal in size and configuration. There is no midline shift or herniation. The major cerebral flow voids are intact. There is mucosal thickening in the paranasal sinuses, left greater than right, with apparent fluid and bubbly secretions. There is also fluid within the bilateral middle ears and mastoid air cells. The orbits, skull, and scalp soft tissues are grossly unremarkable.
1. Findings suggestive of acute sinusitis and perhaps bilateral otomastoiditis, 2. Nonspecific faint patchy focus of T2 hyperintensity in the pons, which could potentially represent incipient progressive multifocal leukoencephalopathy isolated to the pons, but no evidence of intracranial abscess.REFERENCE:Rubin DI, Norris S, Flint R.
