Computed Tomography of Hepatic Cavernous Hemangioma

Computed Tomography of Hepatic Cavernous Hemangioma Fifty hepatic hemangiomas in 38 patients were evaluated by CT using sequential scanning following bolus injection. Lesions were assessed for the following CT features: (a) low density lesion on unenhanced scan; (b) early peripheral contrast enhancement: (c) progressive opacification from the periphery to the center; (d) a delay of at least 3 min before total opacification; and (e) eventual isodense appearance with or without unopacified cleft. The criteria for diagnosis of hepatic hemangioma were (d) and (e) plus at least two of the remaining three features. Forty-eight lesions were identified by CT; 38 displayed all five features, five lesions were missing one feature, and five lesions did not meet the criteria for diagnosis. Larger lesions required a significantly longer period to opacify (p <0.05).

Abstract

Fifty hepatic hemangiomas in 38 patients were evaluated by CT using sequential scanning following bolus injection. Lesions were assessed for the following CT features: (a) low density lesion on unenhanced scan; (b) early peripheral contrast enhancement: (c) progressive opacification from the periphery to the center; (d) a delay of at least 3 min before total opacification; and (e) eventual isodense appearance with or without unopacified cleft. The criteria for diagnosis of hepatic hemangioma were (d) and (e) plus at least two of the remaining three features. Forty-eight lesions were identified by CT; 38 displayed all five features, five lesions were missing one feature, and five lesions did not meet the criteria for diagnosis. Larger lesions required a significantly longer period to opacify (p <0.05). The positive predictive value of CT in the diagnosis of hemangioma was 100&percnt;.
