A Huge Infected Popliteal Cyst Dissecting into Gastrocnemius Mimicking Calf Abscess

Abstract

We report a case of a chronic huge popliteal cyst, which dissected into the gastrocnemius without rupture and was complicated with acute primary infection mimicking calf abscess upon presentation. To the best of our knowledge, it is the largest popliteal cyst with intramuscular dissection reported in the literature. It is noteworthy that infected popliteal cyst is a rare differential diagnosis of calf abscess.
