SCLC treated with 6 cycles chemotherapy. There is a well-circumscribed, diffusely enhancing pineal lesion measuring up to 8 mm in diameter, which is not significantly changed from prior exam. There is minimal cerebral white matter T2 hyperintensity. The brain parenchyma otherwise appears unremarkable. There is otherwise no intracranial hemorrhage or acute infarct. The ventricles and basal cisterns are unchanged in size and configuration. 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. Stable appearing enhancing pineal mass, which may represent a lung cancer metastasis versus a primary pineal tumor. No new intracranial enhancing lesions are identified.2. Minimal non-specific cerebral white-matter T2 hyperintensity suggestive of chronic microvascular ischemia.3. No evidence of intracranial hemorrhage or acute infarct.I personally reviewed the Images and/or procedure with the Resident/Fellow and agree with this report.
