Case Notes
History
41 year old male presenting with a déjà vu feeling then loss of consciouness.Exam
MR diffusion
Prior Study
CT Head and precontrast T1-w MR sequence were not availableMR T1-w post contrast exam
There is remodeling (enlargement and smoothing of the normal bone undulations) of the left middle cranial fossa plus caudal displacement of the left temoral horn compared to the right side. Findings suggest chronic mass effect involving the anterior, mesial left temporal lobe.
T2-w MR
1. Findings are consistent with a low-grade mass (glial or gray matter types) involving the anterior and medial aspects of the left temporal lobe. Chronicity it Is implied by the lack of abnormal contrast enhancement on the T1 weighted post contrast MR, and the remodeling of the left temporal fossa.
2. There are features of recent seizure event involving the left hippocampus, which exhibits feature different than those of diffuse tumoral infiltration.
