Microlissencephaly (MRI)

Sagittal T2 weighted image (A) and axial T2 weighted image (B) show moderate microcephalic brain, almost completely smooth cerebral surface with a thick cortex (short white arrows), and hypoplasia of corpus callosum (black arrow). In addition, the cisterna magna (long white arrow) is enlarged. Axial T1 weighted image (C) shows multiple hyperintense subcortical punctate dystrophic calcifications (black arrows)

• Microlissencephaly - is a heterogenous group of a rare cortical malformations characterized by lissencephaly in combination with severe congenital microcephaly.
• Lishencephaly - ("smooth brain") brain abnormality characterized by the absence of normal convolutions (folds) in the cerebral cortex and an abnormally small head (microcephaly).
• Microcephaly - infants head is much smaller compared to children the same age. (ICD Q02 Microcephaly)
