Hippocampal Sclerosis. Incidental finding
Figure 24. Routine follow-up brain MRI (axial FLAIR sequence)
obtained in a patient with multiple sclerosis, showing typical periventricular
demyelinating lesions. A coronal fast-SE T2W MR image showed unexpected right
hippocampal sclerosis. A detailed clinical anamnesis and further clinical
investigation confirmed the presence of an undiagnosed seizure disorder.
•HS may be detected by chance in brain MR studies obtained in nonepileptic
patients .
Although the
prevalence of HS in the general nonepileptic patient population is uncertain,
it seems to be infrequent, and should prompt further clinical investigation to
exclude a seizure disorder.
