How rare is colpocephaly?
Is colpocephaly rare? Yes. While we are not aware of incidence estimates for colpocephaly, since the first description in 1940, 50 cases have been reported in the medical literature.
How is colpocephaly diagnosed?
After birth, MR imaging can be done to look for cephalic abnormalities. This is the most commonly used method for diagnosing colpocephaly. Physicians look for abnormally large occipital horns of the lateral ventricles and diminished thickness of white matter.
What happens if a baby doesn’t have a corpus callosum?
Some children with agenesis of the corpus callosum have only mild learning difficulties. Intelligence in the child may be normal. Other children may have severe handicaps such as cerebral palsy, severe intellectual or learning disabilities, autism or seizures.
What happens if a baby is missing the corpus callosum?
The corpus callosum is a band of nerve fibers that connects the two sides, or hemispheres, of the brain. These nerve fibers enable the left and right sides of the brain to communicate with each other. In a small number of babies, the corpus callosum is either partially or completely missing.
How rare is agenesis of the corpus callosum?
Agenesis of the corpus callosum (ACC) is a birth defect that occurs when the connections between the right and left sides of a child’s brain don’t form correctly. It occurs in an estimated 1 to 7 out of 4,000 live births.
What is partial agenesis of the corpus callosum?
Agenesis of corpus callosum (ACC) is a rare disorder that is present at birth (congenital). It is characterized by a partial or complete absence (agenesis) of an area of the brain that connects the two cerebral hemispheres. This part of the brain is normally composed of transverse fibers.
What is the prognosis for colpocephaly?
The prognosis for individuals with colpocephaly depends on the severity of the associated conditions and the degree of abnormal brain development. A rare case of colpocephaly is described in literature which is associated with macrocephaly instead of microcephaly. Increased intracranial pressure was also found in the condition.
What does colpocephaly mean?
Subject: Medical Topic: Article. Colpocephaly. Definition: Colpocephaly is a congenital brain condition where underdeveloped white matter before birth results in abnormally large occipital horns (the rear portion of the lateral cavities of the brain). It is characterized by an abnormally small head, mental retardation, and movement disorders.
What is corpus callosum syndrome?
Printable PDF Open All Close All. Acrocallosal syndrome is a rare condition characterized by a brain abnormality called agenesis of the corpus callosum, the presence of extra fingers and toes (polydactyly), and distinctive facial features.
What does the corpus callosum in brain?
The corpus callosum is a band of nerve fibers located deep in the brain that connects the two halves (hemispheres) of the brain. It helps the hemispheres share information, but it also contributes to the spread of seizure impulses from one side of the brain to the other.
