Computed tomography of benign angiomatous lesions of the extremities.
Thirteen patients with benign angiomatous lesions of the extremities were evaluated by CT. The relationship of the lesion to specific muscle groups and fascial planes was defined better by CT than on plain radiography or angiography. Computed tomography without contrast enhancement demonstrated well circumscribed masses of lower attenuation value than the surrounding muscle. Eight of the 11 patients who received intravenous injection of contrast material showed characteristic punctate or curvilinear structures within the mass, which had attenuation values similar to normal blood vessels. The characteristic CT features of benign angiomatous lesions of the extremities are presented.
