BACKGROUND: Prevalence and incidence of @entity99 are estimated from autopsy series only. Although benign and generally asymptomatic, @entity99 can cause serious complications. AIMS: The aim of the study was to assess the prevalence of @entity99 and to attempt to quantify the risk of major complications such as @entity1409 . METHODS: We retrospectively analyzed the radiology database of a Regional University Hospital over a 7-year period: the radiological records of 83,181 @entity1 who had an abdominal computed tomography or magnetic resonance scan were reviewed. Diagnoses made at imaging were reviewed and related to clinical course. RESULTS: @entity99 was diagnosed in 2071 @entity1 (2.5% prevalence). In 226 @entity1 (10.9%), haemangioma had diameter of 4cm or more ( @entity2967 ). The risk of @entity548 was assessed on @entity1 without concomitant @entity5 . Spontaneous @entity548 occurred in 5/1067 @entity1 (0.47%). All 5 @entity1 had @entity2967 : 4 had exophytic lesions and presented with haemoperitoneum; 1 with centrally located @entity5 experienced @entity548 . CONCLUSION: @entity2967 have a low but relevant risk of @entity397 (3.2% in this series), particularly when peripherally located and exophytic. Surgery might be considered in these cases.
