Coronal CT examination in the evaluation of small frontoethmoidal encephalocoeles.

Symptoms producing small front-ethmoidal encephalocoeles are generally identified radiologically. The examination of choice is coronal CT, eventually performed axially with coronal reconstructions, and best with intrathecal contrast material delineating the basal cisterns. Two case reports demonstrate the clinical and radiological problems in identifying small fronto-ethmoidal encephalocoeles.
