Haglund Syndrome with Pump Bump

Abstract

Haglund's syndrome, which is an inflammation of the bursa and a bony enlargement on the back of the heel that most often leads to painful bursitis, is a rare cause of retrocalcaneal pain. The clinical diagnosis is often confusing as the clinical picture may mimic other causes of hindfoot pain such as isolated retrocalcaneal bursitis or hindfoot involvement from more systemic disorders such as seronegative spondyloarthropathies (Reiter's syndrome, ankylosing spondylitis) or rheumatoid arthritis. This report is of a 60-year-old woman with a painful swelling of the right heel, who was diagnosed with Haglund syndrome. The characteristic clinical photograph (showing the prominent 'pump bump'), radiographical and magnetic resonance imaging features are presented.
