The CT findings in two surgically proved cases of spontaneous chronic extradural hematoma are presented. Tapered convex margins, a length greater than 2 cm, and associated normal intervertebral disks are findings that help distinguish chronic extradural hematoma from an extruded disk.
Our experience in 1,024 computed tomography examinations of the head in 954 infants and children performed in a private office is reported. Immobilization in infants was achieved using relatively large dosages of chloral hydrate (as high as 75 mg/kg) supplemented, when necessary, by I.M. Benadryl. The usual dose of chloral hydrate recommended for children is 25 mg/kg as a sedative and 50 mg/kg as a hypnotic. Satisfactory immobilization was accomplished in 350 of the 360 children under 6 years of age. Thus, routine general anesthesia was avoided. The wide spectrum of conditions demonstrated has been tabulated and selectively illustrated.
