 There has been slight interval decrease in the size of the enhancing pineal mass, currently measuring 12 x 12 x 10 mm in the AP, transverse, and craniocaudal dimensions, previously 13 x 14 x 12 mm. The nonenhancing, cystic thalamic components are minimally smaller when compared to the prior study, especially on the right. The endoscopic third ventriculostomy catheter appears patent. The right transverse frontal Ommaya catheter terminates in the region of the right foramen of Monro. The ventricles and sulci are within unchanged in size. There is no midline shift or mass effect. There is no evidence of acute infarction. The skull and extracranial structures are unchanged.
Minimal interval decrease in size of the enhancing pineal mass, with persistent associated peritumoral cystic components within the bilateral thalami.
