This report describes a 22-yr-old professional golfer with acute calcific periarthritis of the proximal interphalangeal joint of the 4th finger. We considered that the major cause for this condition may be the repeated minor traumas to the affected site. Also, since this condition is self-limiting, a correct diagnosis is required to avoid unnecessary tests and surgery.

Iliotibial band (ITB) friction syndrome is a common overuse injury typically seen in the active athlete population. A nodular lesion on the inner side of the ITB as an etiology or an accompanying lesion from friction syndrome has been rarely reported. A 45-year-old male presented with recurrent pain and a movable nodule at the lateral joint area, diagnosed as ITB friction syndrome. The nodule was confirmed as a rare intra-articular fibroma of the tendon sheath (FTS) on the basis of histopathologic findings. We describe the MRI findings, arthroscopic and pathologic features, in this case of intra-articular FTS presenting with ITB friction syndrome.
