Enlarged Iliopsoas Bursa Compressing the Femoral Nerve Resulting in Femoral Mononeuropathy and Denervation Edema

Abstract

Iliopsoas bursitis, although not rare, may manifest clinically as a detectable mass in the groin area. This condition has the potential to apply pressure on the adjacent femoral neurovascular bundle, leading to isolated mononeuropathy.

We present an uncommon case of femoral mononeuropathy in a 46-year-old female patient caused by an enlarged iliopsoas bursa. The case is noteworthy due to its rarity and the clinical and diagnostic challenges associated with assessing individuals with a groin mass, hip flexor weakness, and femoral nerve palsy.
