title: Elbow Stiffness Secondary to Elbow Joint Osteoid Osteoma, a Diagnostic Dilemma.
abstract: We present a 23-year-old man with distal humerus osteoid osteoma referring to our hospital with pain and progressive stiffness. The patient has been suffering from the disease for two years without a certain diagnosis. The radiographies of elbow did not reveal the pathology but further CT scan and MRI studies demonstrated the tumor. The en block resection of the tumor resolved the pain immediately but range of motion remained restricted.
