A symptomatic pelvic rib.

Pelvic rib is a rare anomaly where ectopic rib is found in a pelvic region. It is usually found occasionally in asymptomatic patients. We report a case of 15-year-old male, diagnosed with a symptomatic pelvic rib. It had an unusual presentation creating a pseudotumour associated with pain and reduced range of motion in the hip joint. Patient was operated on with good result and final diagnosis was confirmed in pathological examination. (Folia Morphol 2018; 77, 2: 406-408).
