Presentation
Abdominal pain.
Patient Data
Large hypoattenuating mass lesion with occupies nearly the entire 7th and 8th hepatic segments, its markedly hypoattenuating centre likely representing necrosis. The lesion shows peripheral, globular enhancement on arterial phase and progressive centripetal enhancement on venous and delayed phases, without completely filling. Adjacent area of perfusion changes at its inferolateral aspect, more noticeable on the arterial phase. No intralesional fat, calcification, or haemorrhage, and evidence of rupture or capsular retraction. The mass exerts a mass effect mainly on the middle hepatic vein (stretching it at its medial edge near its confluence with the IVC; no thrombosis) and causes central minimal intrahepatic bile duct prominence.
Retroaortic left renal vein.
Case Discussion
The case shows typical features of a right lobe giant hepatic haemangioma.
