Calcific tendinitis of hand and foot is rare and frequently misdiagnosed because of its rare incidence and its similar clinical presentation to other conditions such as infection. Awareness of the typical location as well as familiarity with the imaging findings is essential for making a correct diagnosis of this rare condition. We report four cases of calcific tendinitis of hand and foot, occurring in the flexor hallucis brevis, abductor digiti minimi, and abductor pollicis brevis.
