Computed tomography of hepatic cavernous hemangioma

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