title: Bilateral isolated internal iliac aneurysms presenting as pelvic tumours.
abstract: A case of a bilateral isolated internal iliac aneurysm is presented. A male patient of 74 years of age had a sudden attack of pain in the right lower abdomen. A superficial haematoma was the only finding at primary ultrasonography (US), while seven weeks later a control US visualised a pelvic expansion, but the aetiology was not recognised. The CT finding was pathognomonic for an aneurysm, the diagnosis being "bilateral iliac aneurysms". Digital subtraction angiography (DSA) defined the aneurysms as existing in the internal iliac arteries.
