CT of cerebral hemiatrophy.

Computed tomography (CT) findings in 10 cases of cerebral hemiatrophy are described. The CT appearance is typical and reflects the pathologic changes of unilateral loss of brain substance and calvarial thickening. In four patients with a mild form of the disease, a correct analysis of the pain skull radiographs was made only in retrospect. CT was found superior to plain skull films in the demonstration of subtle calvarial thickening and changes affecting the base of the skull.
