Acute calcific tendinitis (ACT) is a relatively uncommon disorder of the hand and wrist. ACT is a well-known condition of the shoulder, but it often goes unrecognized when occurring in the hand or wrist. The overall lack of familiarity along with the non-specific symptoms associated with ACT frequently leads to misdiagnosis or delay in diagnosis. We report a case of acute calcific tendinitis occurring in the carpal tunnel which is a rare presentation.
