History of papillary serous carcinoma status post brain biopsies. There are postoperative findings related to right occipital lobe biopsy without evidence of residual enhancing lesion. There is residual surrounding confluent T2 hyperintensity. There is an unchanged enhancing dural based lesion that measures up to 5 mm along the inferior surface of the left tentorium, near the apex. There are punctate foci of susceptibility effect without associated enhancement in the right cerebellum, left frontal lobe periventricular white matter, and medial right occipital lobe. There is no evidence of acute infarct. There are scattered foci of cerebral white matter T2 hyperintensity without associated enhancement. There is mild diffuse cerebral volume loss. There is no midline shift or herniation. The major cerebral flow voids are intact. There are bilateral lens implants. The skull and scalp soft tissues are grossly unremarkable. There is fluid in the left maxillary and right sphenoid sinuses and scattered paranasal sinus mucosal thickening. There is also fluid within the bilateral mastoid air cells.
1. Post-treatment findings in the right occipital lobe, without evidence of recurrent tumor. 2. An unchanged enhancing dural based lesion that measures up to 5 mm along the inferior surface of the left tentorium may represent a meningioma or metastasis.3. Punctate foci of susceptibility effect without associated enhancement in the right cerebellum, left frontal lobe periventricular white matter, and medial right occipital lobe are nonspecific and may represent chronic microhemorrhages, perhaps related to amyloid angiopathy.4. Findings suggestive of acute sinusitis and mastoiditis.
