Linear encephalomalacia mimics closed-lip schizencephaly

Case contributed by Mohammad Taghi Niknejad
Diagnosis almost certain

Presentation

Incidental finding in an old patient which presented with headache.

Patient Data

Age: 70 years
Gender: Male

A right parietal parenchymal cleft extends from the cortical surface to the lateral ventricle without grey matter lining.

Case Discussion

Features on axial CT images are most consistent with a linear track of encephalomalacia that mimics a closed-lip schizencephaly. The cleft is not lined by grey matter, which is a characteristic feature of schizencephaly.
