Ischiofemoral Impingement Syndrome Secondary to Arteriovenous Malformation of the Quadratus Femoris

Abstract

Case: Ischiofemoral impingement syndrome (IFIS), an unusual presentation of hip pain, is frequently missed in clinical practice. We report a case of a 27-year-old man with complaints of gradual onset nonprogressive right gluteal pain with hip movement restriction for the past 5 years that was not relieved with conservative measures. Right hip magnetic resonance imaging revealed a vascular abnormality of the right quadratus femoris muscle suggestive of IFIS. This abnormal muscle was surgically excised, and its histologic evaluation was remarkable for an arteriovenous malformation. Conclusion: The patient's longstanding symptomatic IFIS was ultimately attributed to a rare arteriovenous malformation of the quadratus femoris that resolved with surgical excision.

Deep Gluteal Pain in Orthopaedics: A Challenging Diagnosis

“…13,14 Case reports have described associated bursae, iatrogenic injury, and space-occupying lesions within these muscles such as hematomas, myositis ossificans, arteriovascular malformations, and abscesses. 13,15…”

“…13,14 Case reports have described associated bursae, iatrogenic injury, and space-occupying lesions within these muscles such as hematomas, myositis ossificans, arteriovascular malformations, and abscesses. 13,15 The proximal hamstring is itself an important pain generator in this area. Puranen and Orava 16 coined the term HS to describe gluteal pain secondary to tendon pathology such as tendinitis and tears or SN-irritating fibrotic bands.…”
