Findings:
There is hippocampal asymmetry (right smaller than the left). The hippocampi demonstrate T2/FLAIR hyperintensity with reduced internal architecture on the right. The temporal horn is mildly prominent on the right.
The remainder of the intracranial appearances are unremarkable. No abnormal signal on the susceptibility-weighted images or diffusion/ADC images is identified.
There is no hydrocephalus or midline shift.
The pituitary gland is normal.
Mild mucosal thickening is seen in both maxillary sinuses. Bilateral obliteration of the mastoid air cells is seen on the left side. The paranasal sinuses and the mastoid air cells are otherwise clear.
Conclusion:
Signal abnormality of the hippocampi on both sides with decreased internal digitations on the right. Given the clinical history, features are suggestive of bilateral mesial temporal sclerosis.
