Venous Aneurysm of Finger. Unusual Location and Difficulty of Diagnosis

Venous aneurysm of the finger is a rare condition. We describe a 45-year-old woman with pain and a mass on the left fifth finger. Aspiration of the mass was performed, revealing that it contained blood and thrombus. Duplex scanning showed a cystic mass with no blood flow that seemed to be connected to the distal interphalangeal joint. Surgery was performed, and the lesion was found to provide a connection from the superficial digital vein to the deep digital vein. Accordingly, a diagnosis of venous aneurysm of the finger was made. Resection of the aneurysm was performed successfully, and the pain resolved.
