Abstract

An old man was presented with pain and swelling in the right ankle along the course of peroneal muscles. Blood tests were normal. X ray and MRI revealed bilateral hypertrophied peroneal tubercles, peroneal tendinopathy and extensive synovial effusion along both peroneal tendons, as well as along the flexor halluces longus muscle and in the subtalar joint. Peroneal tenosynovitis was secondary to the age-related changes in the structure of connective tissue, and to repetitive overload exposure rather than the irritation by the hypertrophied peroneal tubercle. The patient was cured by conservative treatment.
