What Is It?

Case by Dr Hidayatullah Hamidi and Dr Mai-Lan Ho et al.

This is a T1 MRI brain demonstrating porencephaly, or encephalomalacia resulting in a cyst in the cerebral hemisphere. Porencephaly typically results from ischemic insults to a fetal or neonatal brain. Lined with gliotic white matter, the cysts often develop adjacent to the sylvian fissures or central sulci. Patients with porencephaly often present with cognitive delay, congenital hemiplegia, chronic spasticity and/or epilepsy.
