Bleeding adenoma in young man with sudden and acute upper abdominal pain. (a-b) Ultrasound, B-mode (a) and color-Doppler (b) imaging show heterogeneous lesion without significant vascularization. (c–f) CT confirms heterogeneous hyperdense bleeding mass with persistent vascularized tissue in the lower portion of the lesion (arrowheads). (g) Axial T2w image shows mixed heterogenous bleeding capsulated mass (arrows) in S VIII. (h-i) T1w in- and out-phased images confirm intralesional hemorrhage. (j–m) MR dynamic study shows vascularized tissue in the lower portion of the lesion (arrowheads). (n–p) DSA before embolization. Note hypervascular tissue in the lower part of the lesion (arrow). (q-r) DSA after embolization, complete devascularization of the nodule. (s) Cut section of the resected lesion shows large hemorrhagic component (star).
