CLINICAL HISTORY.—This 2-month-old boy was seen because of a peculiarly shaped head. There were no other complaints. The mother's pregnancy had been uneventful and the delivery normal. The shape of the head had been apparent since birth. Birth weight was 3,436 gm (7 lb 9 oz); he had developed well. The infant weighed 4,535 gm (10 lb) on admission. The forehead had a keel-shaped appearance, and the anterior fontanel was open and flat. The appearance of the head was best appreciated when viewed from above. Epicanthal folds were prominent, and the eyes seemed closer together than usual. The only other abnormal finding, upon physical examination, was a mild hypospadias. Hemoglobin, WBC and urinalysis were within normal limits. NPN was 36 mg/100 ml. Other laboratory studies were not done.
