Misdiagnosis of cystic tuberculosis of the olecranon

Abstract

Osteoarticular tuberculosis accounts for only 1–2% of all cases of tuberculosis, and tuberculosis of the olecranon is extremely rare. In the present study, we describe a case of a 54-year-old woman with cystic tuberculosis of the olecranon, which was initially misdiagnosed as a malignant tumor. The patient subsequently underwent regular antituberculosis treatment and autogenous bone graft, which resulted in relief of all symptoms.
