Colpocephaly

Colpocephaly is a kind of cephalic disorder that produces an abnormal enlargement of the occipital horns - the back part of the lateral ventricles of the brain. This growth comes about when there is an underdevelopment or lack of thickening of the white matter in the rear cerebrum.

Colpocephaly is characterized by an abnormally small head (referred to as microcephaly) and mental retardation. Some other qualities of the disorder include motor abnormalities, muscle spasms, and seizures.

Though the exact cause of Colpocephaly is unknown, researchers believe that the disorder may arise from an intrauterine disturbance that occurs between the second and sixth months of pregnancy. Often times, Colpocephaly may be detected late in pregnancy, but is generally misdiagnosed as hydrocephalus (excessive accumulation of cerebrospinal fluid in the brain). An accurate diagnosis can be given after birth when signs of mental retardation, microcephaly, and seizures are present.

Currently, definitive treatment options for colpocephaly do not exist. Anticonvulsant medications can be taken to prevent seizures, and doctors try to prevent contractures (shrinkage or shortening of muscles). The prognosis for individuals with colpocephaly depends on the severity of the associated conditions and the level of abnormal brain development. Some children may benefit from special education.
