47 year old male patient with prolactinoma, stroke. Follow up examination. Brain: There is a focus of restricted diffusion with associated faint enhancement within the posterior left basal ganglia and internal capsule compatible with a subacute infarct. There is no associated susceptibility artifact to suggest hemorrhage. There is otherwise scattered foci of white matter T2/FLAIR signal abnormality in the frontal lobes compatible with chronic small vessel ischemic disease. The ventricles and basal cisterns are stable in size and configuration. The orbits and scalp soft tissues are grossly unremarkable.Pituitary:Redemonstration of an expansile sellar mass with suprasellar extension which encases the distal right ICA and involves the right aspect of the cavernous sinus, sphenoid sinus, clivus, and petrous apex. Compared to the prior study, the mass is less homogeneous in enhancement and decreased in size. The lesion measures 31 x 35 x 26 mm (AP x transverse x craniocaudal), previously 35 x 41 x 31 mm.
1. Evolving subacute infarct in the left basal ganglia.2. Decrease in size of a sellar/cavernous sinus mass.
