Delayed intra-articular pseudoaneurysm of the dorsalis pedis artery following arthroscopic Broström results in an unusual clinical presentation.

Abstract

Pseudoaneurysms of the dorsalis pedis artery are rare complications following arthroscopic surgery. This manuscript reports a case of an intra-articular pseudoaneurysm presenting nearly 5 months following an arthroscopic Broström procedure. The rarity of this complication and the patient's unusual clinical presentation prompted the use of imaging to diagnose the problem and guide management. Although imaging artifacts are often a nuisance, recognition of clinically relevant artifacts can help make a diagnosis. This case illustrates such a situation.
