Gluteal Diclofenac Injection Lesion Can Mimic an Abscess on MRI

Abstract

Intramuscular diclofenac injection is commonly used for pain management. Case reports have shown that after injection of diclofenac, local complications can occur but still underestimated. Acute muscle trauma can be found at the injection site. Limited studies have dealt with muscular radiological findings after diclofenac injection. This is a case report of an incidental gluteal lesion that was suggestive of an abscess on MRI following diclofenac intramuscular injection.
