Initial staging of recently diagnosed lung cancer. There are punctate foci of susceptibility effect in the posterior left Heschl gyrus region and right frontal corona radiata. Otherwise, there is no evidence of intracranial tumors. There is no evidence of intracranial hemorrhage or acute infarct. There is mild cerebral white matter T2 hyperintensity, predominantly in a periventricular distribution. The third and lateral ventricles are prominent, perhaps disproportionately with respect to the sulci and there is a prominent jet of cerebrospinal fluid in the third ventricle. There are also prominent cerebrospinal fluid spaces posterior to the cerebellum and a small left middle cranial fossa arachnoid cyst. There is no midline shift or herniation. The major cerebral flow voids are intact. The skull, paranasal sinuses, and scalp soft tissues are grossly unremarkable. There is a right lens implant. There is fluid in the right mastoid air cells.
1. Punctate foci of susceptibility effect in the posterior left Heschl gyrus region and right frontal corona radiata may represent a chronic microhemorrhages or perhaps an atypical metastases. Otherwise, no evidence of intracranial tumors.2. Findings suggestive of possible normal pressure hydrocephalus.3. Mild cerebral white matter T2 hyperintensity, predominantly in a periventricular distribution is nonspecific, but may represent chronic small vessel ischemic disease.
