Proximal iliotibial band syndrome: case report

Abstract
in English, Portuguese

The overuse injuries in the hip joint occur commonly in sports practitioners and currently due to technical advances in diagnostic imaging, especially magnetic resonance imaging (MRI), are often misdiagnosed. Recently, a group of people were reported, all female, with pain and swelling in the pelvic region. T2-weighted MRI showed increased signal in the enthesis of the iliotibial band (ITB) along the lower border of the iliac tubercle. We report a case of a 34 year old woman, non-professional runner, with pain at the iliac crest with no history of trauma and whose MRI was compatible with the proximal iliotibial band syndrome.

As lesões por sobrecarga na articulação do quadril ocorrem comumente em praticantes de esporte e atualmente, por causa do avanço das técnicas de diagnóstico por imagem, especialmente a ressonância magnética (RM), são frequentemente diagnosticadas. Recentemente, foi estudado um grupo de pacientes, todos do sexo feminino, com quadro de dor e edema na região do tubérculo ilíaco. A RM ponderada em T2 demonstrava aumento de sinal na êntese da banda iliotibial (BIT) ao longo da margem inferior do tubérculo ilíaco. Relatamos um caso de uma mulher de 34 anos, corredora não profissional, com quadro de dor na crista ilíaca sem história de trauma e cuja RM era compatível com a síndrome da banda iliotibial proximal.

Magnetic resonance imaging in the coronal plane (left) and sagittal plane (center) with T2 weighting and fat saturation, and in the axial plane after contrast administration (right), which demonstrates focal thickening of the ITB (arrows) at its origin at the iliac crest, adjacent to the iliac tubercle (asterisk), with a small intrasubstance rupture/delamination and surrounding inflammatory alterations, which also involve the underlying fibers of the gluteus medius, at its origin in the external plate of the ilium. Note the evident post-contrast highlighting on the right side, suggestive of an inflammatory component.
