Three hemangiomas of the face and orbit are studied with dynamic computerized tomography (CT). This noninvasive technique has the advantage of simultaneous bone and soft tissue visualization at the time of peak contrast enhancement, and it precludes the potential complications of arteriography and biopsy. The hemangiomas are precisely delineated with intense contrast; the sharp peak and rapid uninterrupted runoff of the computer-generated plot of contrast concentration (CT number) versus time is characteristic of this lesion. It is suggested that the progress of hemangioma involution may be documented by the change in contrast distribution in sequential dynamic CT studies. Dynamic CT is recommended for the evaluation of head and neck vascular tumors.
