Abstract:
PURPOSE: The purpose of this study was to evaluate the frequency, location, and appearance of increasedattenuation of the liver adjacent to a mass during arterial-phase spiral CT in patients with hemangioma. Thecharacteristics of the mass associated with these findings were also evaluated. MATERIALS AND METHODS: Usingspiral CT, 153 lesions in 114 hepatic hemangioma patients were retrospectively reviewed. We evaluated thefrequency, location, and appearance of increased hepatic attenuation adjacent to the hemangioma, and determinedwhether lesion size varied according to whether or not there was increased hepatic attenuation. RESULTS: Areas ofincreased hepatic attenuation adjacent to the hemangioma were identified in 10.5% of cas-es(16/153) and seen inmasses which showed a homogeneously hyperdense (11/16, 69%) or peripherally hy-perdense pattern (5/16, 31%). Thelocation of increased hepatic attenuation was commonly the peripheral por-tion (9/16, 56%), and increased hepaticattenuation was frequently wedge shaped of the mass (11/16, 69%). Lesion size did not vary according to whether ornot there was increased hepatic attenuation. CONCLUSION: Increased hepatic attenuation adjacent to a hemangiomais not rare, and is usually located periph-eral to the mass. It is common in a mass showing a homogeneouslyhyperdense pattern.
