A True Aneurysm of the Great Saphenous Vein Presented as an Inguinal Mass

ABSTRACT

Primary venous aneurysm is a rarely encountered vascular disease in clinical practice. In contrast to deep venous aneurysm, superficial venous aneurysms are at low risk for thrombotic complications. Surgical excision is often recommended when they become symptomatic. We present here a case of true aneurysm of the great saphenous vein (GSV) in a 16-year-old girl who complained of a painful mass in the right inguinal area. Doppler sonography and CT-venography showed a vascular pool in the right inguinal area, and this was suspicious for being an aneurysm or a pseudoaneurysm that originated from the GSV. This saccular mass was completely excised and it was proved to be a true aneurysm of the great saphenous vein on the pathologic examination. Venous aneurysm should always be considered in the differential diagnosis of a subcutaneous mass, although it is a rare vascular anomaly.
