Volar ganglion cyst of the wrist simulating a radial artery pseudoaneurysm: A case report

Pseudoaneurysms (PAs) of the radial artery are common following percutaneous cardiac catheterization. Ganglion cysts (GCs) are also a commonly identified entity in patients with history of trauma, osteoarthritis or inflammatory joint diseases. It can be challenging to differentiate a GC from a PA of the radial artery if the ganglion is located adjacent to the radial artery, especially when the medical history is suspicious. We herein present a rare case of a GC in the wrist simulating an iatrogenic PA of the radial artery in an elderly patient who had undergone to a recent diagnostic cardiac catheterization at the same site. Clinicians should be aware of the diagnostic techniques for the study of superficial lesions of the wrist in order to recognize the possible pathologies in the differential diagnosis.
