    Abstract

    The sonographic and CT appearances of 9 large cavernous hemangiomas of the liver were studied. On sonography, 6 masses (67%) exhibit heterogenous echo pattern; where in 2 patients the echotexture was a mixture of hypoechoic and isoechoic areas and in 4 patients there are varying amounts of bright hyperreflective areas similar to the texture typical of small hemangiomas. The masses were predominantly hypoechoic in the remaining 3 patients (33%). Incremental bolus or bolus-infusion dynamic CT showed peripheral contrast enhancement of varying intensities and thickness in all patients. The lesions were incorrectly diagnosed as hepatomas in 4 patients, suspected as hemangiomas with a differential diagnosis of hepatomas in 4 patients and an early liver abscess in 1 patient. It is concluded that large cavernous hemangiomas of the liver do not exhibit the typical homogenous hyperreflective echotexture as exhibited by small lesions and they mimic primary and secondary hepatic neoplasms. However, the diagnosis of hemangioma should be entertained when such a mass contains bright hyperechoic areas within its heterogenous echo pattern and exhibit peripheral enhancement on contrast enhanced CT. In addition to correlation with appropriate clinical information, confirmation of diagnosis include delayed scanning during a routine incremental bolus dynamic CT, single-slice dynamic contrast enhanced CT, angiography or isotope scintigraphy and magnetic resonance imaging depending on the availability of facility.
