Detailed Information on Megalencephaly

Posted on 16th | Posted by admin in Health

Megalencephaly is a type of cephalic disorder and also called macrencephaly.

Megalencephaly is marked by an abnormally large, heavy, usually malfunctioning brain. The head may be enlarged at birth or become abnormally big in the early years. The brain weight is greater than standard for the age and sex of the baby or child. This results in a large, often asymmetrical head. Head enlargement may be evident at birth or the head may become abnormally large in the early years of life. Symptoms of megalencephaly may include delayed development, convulsive disorders, corticospinal (brain cortex and spinal cord) dysfunction, and seizures.

Choroid plexus carcinoma is an uncommon, cancerous kind of this tumor. It is not treated with operation only, but requires extra therapy including chemotherapy and sometimes radioactivity therapy. Hydrocephalus may remain and is managed by CSF shunting.

Choroid plexus papillomas are one of the most common tumors of the nervous system in infants. The most frequent early symptoms, megalocephalia and vomiting, caused by elevated intracranial pressure often lead to a diagnosis only at a critical clinical stage. CPPs are commonly observed in the lateral ventricles of children, but they can be encountered in adults. While the vast majority of these neoplasms are benign, a small percentage can be malignant.CPPs arise from the single layer of cuboidal epithelial cells lining the papillae of the choroid plexus. The choroid plexus is associated with the ventricular lining of the body and trigone.
