It is an exceptionally rare condition, with mostly scattered case reports available. The aim of this study was to describe this rare condition, possible associated risk factors, and usefulness of multislice-CT (MS-CT) angiogram in its diagnosis prior to intervention. Methods: A retrospective review of patients diagnosed with ISIH. Radiological records of haemoperitoneum from a single tertiary hospital in 2006-2013 were analysed, and the cases of ISIH were identified. Demographics (including pre-morbid hypertension status), abdominal aortic calcification as a measure of atherosclerotic changes, MS-CT angiogram +/− conventional digital subtraction angiograph images, surgical records and outcomes were reviewed. Results: 425 cases of haemoperitoneum were retrieved from hospital radiology database from 2006 to 2013, and 5 patients (1.1%) diagnosed with ISIH were identified (4 males, 1 female, mean age of 64years). 4 out of 5 patients (80%) had a history of hypertension (mean 150/90mmHg) and 3 patients had moderate abdominal aortic atherosclerosis. MS-CT angiogram was able to diagnose the bleeding source in 4 out of 5 patients, while the bleeding source remained occult in the last patient even with both MS-CT and traditional DSA angiography. Patients who underwent either embolization or surgery had no further re-bleeding in clinical follow up, ranging from 5 to 8years. Conclusions: Hypertension and abdominal aortic atherosclerosis appear to be associated risk factors for ISIH, and MS-CT angiogram has a high sensitivity in detecting the site of haemorrhage. An integrated angiographic and surgical approach is important in managing patients with ISIH.
