Iliopsoas Tendon Injury In an Adolescent: A Case Report

Abstract

Background: The Iliopsoas tendon injuries are generally considered uncommon. Especially in children and adolescents, the iliopsoas injury usually occurs in conjunction with avulsion of the lesser trochanter. We reported a rare case of a partial tear of the left psoas major tendon in an adolescent patient. Case Report: A 14-year-old-male who had a left inguinal pain came to our hospital for consultation. The injury occurred earlier when he was playing a basketball game he turned on a pivot and he suddenly felt left inguinal pain. As a result of the sudden pain caused by the movement he could not move his left hip joint by himself. Neurological examination revealed no motor or sensory deficits with normal reflexes. On the MRI, the left psoas major tendon showed up as swollen and was separated from the left iliacus tendon when compared to the right side. The left psoas major tendon and myotendinous junction showed high signal intensity suggestive of a partial tear on STIR axial image. The lesser trochanter showed slightly high signal intensity when compared to the opposite side but showed no evidence of an avulsion fracture. Conclusion: The Iliopsoas tendon injuries without lesser trochanteric avulsion in children and adolescents are distinctly uncommon. There is an estimated prevalence of 0.66%. In future we would suggest, we need to evaluate both the lessor trochanter and the insertion of the iliopsoas tendon to rule out lesser trochanter avulsion on the MRI.
