ABSTRACT
OBJECTIVE: To report a case of pseudoaneurysm of the abdominal aorta due to retroperitoneal enlarged lymph nodes. MATERIALS AND METHODS: A 40 years old patient, with known sarcoma and metastatic retroperitoneal lymph nodes was referred for abdominal ultrasound because severe abdominal pain after defecation. RESULTS: The Doppler examination revealed magma of retroperitoneal lymph nodes surrounding the abdominal aorta inside of which a saccular collection of circulating blood, communicating with the aorta, was detected. The spectrum registered in the channel revealed a bidirectional flow compatible with a pseudoaneurysm. MR angiography confirmed the diagnosis. Successful occlusion was done by coil embolization. CONCLUSION: Pseudoaneurysms of the abdominal aorta are very rare. We report the first case of pseudoaneurysm arising in retroperitoneal lymph nodes. Diagnosis by Doppler ultrasound allowed a rapid treatment by embolization.

The usefulness of three-dimensional angiography is not fully established except for neurovascular diseases. We report a case of significant renal artery stenosis not shown on conventional angiography because of its orientation along the axial plane, where 3D imaging allowed complete analysis of the lesion leading to endovascular treatment.
