Lesion of uncertain significance. There is no significant interval change in size of the patchy T2 hyperintense lesion that measures up to approximately 14 mm, involving the inferomedial left basal ganglia, with apparent compression of the adjacent optic pathway. There is also an unchanged punctate focus of enhancement in the central portion of the lesion. However, there appears to be an additional punctate focus of enhancement more inferiorly within the lesion. There is no evidence of intracranial hemorrhage or acute infarct. The ventricles and basal cisterns are normal in size and configuration. There is no midline shift or herniation. The major cerebral flow voids are intact. The orbits, skull, and scalp soft tissues are grossly unremarkable. There is scattered paranasal sinus mucosal thickening and retention cyst formation.
No significant interval change in size of the patchy T2 hyperintense lesion with a punctate focus of enhancement involving the inferomedial left basal ganglia, although there appears to be an additional punctate focus of enhancement. A neoplastic remains a salient possibility for this lesion.
