The survivors often have mental retardation accompanied by epilepsy, and the prognosis is poor Br > gyral micromalformations or multiple gyral micromalformations occur in some areas of the cerebral or cerebellar cortex, often with bilateral symmetrical distribution. Gyrus megacephalus symptoms? Let's talk about it.

Gyrus megacephalus symptoms?

(1) Megagyrus deformity incomplete absence of gyrus, only for the reduction of gyrus, increased volume, known as megagyrus deformity. Megagyrus deformity is the first secondary gyrus reduction, severe cases can only have the main gyrus. Gyrus megacephalus is often associated with anucleus.

(2) Gyromedullary gyromedullary gyromedullary gyromedullary gyromedullary gyromedullary gyromedullary gyromedullary gyromedullary gyromedullary gyromedullary gyromedullary gyromedullary gyromedullary. This is the most common malformation in the gyrus malformation, which can occur in some areas of the brain or cerebellar cortex, and is often distributed symmetrically on both sides. It is common in children with congenital hydrocephalus.

(3) Thin and small gyri with clusters, irregular arrangement and increased sulci are called multiple gyral malformations. Microscopically, the development of nerve cells remained in the primitive cell stage. The cortex is only composed of Ⅰ - Ⅳ layers, and the Ⅱ layer is usually lace like.
