44-year-old female status post surgical resection of a colloid cyst, now with mild memory impairment. There are unchanged postsurgical findings related to bifrontal craniotomy and resection of a colloid cyst via a transcallosal approach. There is new cortical gyriform high T2 signal and enhancement in the left temporal and occipital lobes and in the inferior left precentral gyrus. There is unchanged curvilinear increased T2 signal in the anterior right frontal lobe consistent with a prior ventriculostomy catheter tract. There is unchanged nonspecific thin confluent high T2 signal in the periventricular white matter along the bilateral lateral ventricles. There is no midline shift or herniation. There is unchanged asymmetry of the lateral ventricles and mild diffuse cerebral and cerebellar vermis volume loss. The orbits and paranasal sinuses are unremarkable.
1. Late subacute infarction affecting the left temporal and occipital lobes and left precentral gyrus consistent with prior infarction.2. Unchanged postoperative findings related to colloid cyst resection without evidence of residual or recurrent cyst.3. Mild diffuse cerebral and cerebellar vermis volume loss may be related to alcohol use. I personally reviewed the Images and/or procedure with the Resident/Fellow and agree with this report.
