Death due to non-traumatic hemoperitoneum in Milan 2002–2016, with focus on two cases of abdominal apoplexy (idiopathic spontaneous hemoperitoneum) and review of the literature

none6noAbdominal apoplexy, also known as idiopathic spontaneous hemoperitoneum, is a rare event related to sudden death, whose diagnosis and treatment is extremely challenging and whose pathologic mechanisms are still mainly unknown. It is frequently associated with vascular disorders (alterations in the vascular structures) and mainly linked to liver cirrhosis. However, the presence of hemoperitoneum may in such cases pose many challenges to forensic post-mortem examinations since the source of bleeding remains often unknown even after a careful and thorough dissection. The Authors present two cases of sudden death related to massive hemoperitoneum (4,650 ml in case 1 and 5,100 ml in case 2) occurred in two cirrhotic males aged 49 and 51: no traumatic injuries were detected and the source of bleeding was not identified although a careful dissection of organs and vascular structures was performed. Rare cases have been already described in the literature, only as case reports, and no systematic studies have been performed on this issue. Nevertheless, this event ought to be taken into account as a cause of sudden death in people with advanced liver disease. A general glimpse is provided among the different causal mechanisms and the challenges within forensic pathology.noneAlessio Battistini; Matteo Marchesi; Alberto Amadasi; Alessandra Rancati; Guendalina Gentile; Riccardo ZojaAlessio Battistini; Matteo Marchesi; Alberto Amadasi; Alessandra Rancati; Guendalina Gentile; Riccardo Zoj
