case_images: Magnetic resonance imaging of the brain. Representative (A) parasaggital and (B) coronal pre-operative T1-weighted imaging after contrast administration demonstrates an avidly enhancing multilobulated sellar lesion causing mass effect upon the optic apparatus, as well as notable displacement of the left uncus and hippocampal gyrus, resulting in compression of the medial temporal lobe. (C) Coronal pre-operative T2-weighted FLAIR shows mild parenchymal edema within the adjacent temporal lobe. Repeat imaging obtained 4 months after surgical decompression revealed decreased size of the enhancing lesion on (D) parasaggital and (E) coronal T1-weighted imaging after contrast administration with resultant diminished mass effect on the left medial temporal lobe and (F) absence of edema on T2-weighted FLAIR imaging.

case_images: After initiation of anti-seizure therapy with levetiracetam, magnetic resonance imaging (MRI) of the brain was obtained, demonstrating a large sellar mass, extending into the left cavernous sinus and compressing the optic chiasm, as well as superiorly directed growth into the temporal fossa, abutting the left uncus and hippocampus, resulting in mild mass effect upon the medial left temporal lobe with associated parenchymal edema (Figures 1A-C). Repeat MRI obtained 4-months after surgery demonstrated stable residual tumor on the temporal lobe and resolution of parenchymal edema (Figures 1D-F).
