Forearm Inflammatory Intramuscular Collection

Clinical History

A 51-year old man presented with an acute large swelling on the left forearm with erythema and tenderness.

Case Description

Ultrasound performed using a linear transducer at 14 MHz revealed a large hypervascular collection within the intramuscular layer of the affected forearm suggestive of an abscess.

Diagnosis/ Discussion/ Treatment/ Follow up

A further ultrasound performed 3 months later revealed a significant reduction in the said collection, still some internal vascularity, and a tract to the skin surface suggestive of a resolving collection.
