Colpocephaly is a congenital brain abnormality. The occipital horns (the posterior or rear portion of the lateral ventricles of the brain become larger than normal because white matter in the posterior cerebrum has failed to develop or thicken.
There is uncertainty about the cause of colpocephaly, it is believed to be due to some kind of disturbance in the foetal environment. The studies have identified that it occurs between the second and sixth months of pregnancy.
Colpocephaly, one of a group of structural brain disorders known as cephalic disorders, is characterized by microcephaly (an abnormally small head) and mental retardation. Other features may include movement abnormalities, muscle spasms, and seizures.
The condition may be diagnosed late in pregnancy, although it is often misdiagnosed as hydrocephalus (excessive accumulation of cerebrospinal fluid in the brain). It may be more accurately diagnosed after birth when signs of mental retardation, microcephaly, and seizures are present.
There is no definitive treatment for colpocephaly. Anticonvulsant medications are often prescribed to prevent seizures, and doctors rely on exercise therapies and orthopedic appliances to reduce shrinkage or shortening of muscles.
