EVALUATION OF PARTIAL LOSS OF HIPPOCAMPAL STRIATIONS IN CASES OF HIPPOCAMPAL SCLEROSIS.

Partial loss of hippocampal striations (PLHS) is a sensitive indicator of hippocampal sclerosis. This study was done to nd out whether PLHS is a more sensitive indicator of hippocampal sclerosis compared to other signs obtained during imaging using 1.5T MRI at a tertiary care setup. Methods: This was a retrospective study. The study was conducted after obtaining clearance from the institutional review committee. Patients with a history of seizures and clinical suspicion of hippocampal sclerosis were evaluated with 1.5 1.5T Siemens Magnetom Essenza MRI. A seizure protocol was employed for imaging. The following parameters were evaluated. Ÿ Partial loss of hippocampal striations. Ÿ The altered signal intensity of the hippocampus. Ÿ Hippocampal atrophy. Ÿ Loss of internal architecture (loss of inter-digitations). Results: Partial loss of hippocampal striations was seen in 14 (29.16%) cases of the 48 cases evaluated. Altered signal intensity in the hippocampus was seen in 13 (27.0%) cases, Hippocampal atrophy in 11 (22.9%) cases, and loss of interdigitations in 11 (22.9%) cases. Conclusions: With the above results, we conclude that the presence of partial loss of hippocampal striations is more commonly seen in cases of hippocampal sclerosis than other classic signs of hippocampal sclerosis.
