Larger than normal head.
An enlarged head.
The condition of having an unusually large head.
Abnormality (usually but not always congenital) characterized by an abnormally large head and brain, usually resulting in mental and growth retardation. It differs from hydrocephalus in that the overgrowth is symmetrical, and there is no increased intracranial pressure.
A congenital condition in which the head and brain are abnormally large in comparison with the rest of the body. Macrocephaly is associated with enlarged ventricles (hydrocephalus) or increased fluid and failure to develop parts of the brain (hydranencephaly).
Abnormal largeness of the head in relation to the rest of the body.
