The diagnosis of pyomyositis in the pelvic region is difficult, as its incidence is relatively, with symptoms that mimic those of discogenic pain. Sciatica is a common presentation of a prolapsed lumbar disc. Less common causes, such as spinal stenosis, pelvic tumors or even primary nerve tumors can also cause these symptoms. Magnetic resonance imaging (MRI) is a useful diagnostic tool. Herein, the case of a patient with an acute pyogenic infection in the iliopsoas muscle, presenting with sciatica, is reported. This is a rare infective disease, which if promptly treated with intravenous antibiotics, can be completely resolved; otherwise, it can result in deep abscess formation, sepsis and death.

Bacterial infection of skeletal muscle can lead to the formation of abscesses. Primary pyomyositis is typically seen in tropical countries, and Staphylococcus aureus is the commonest causative organism. We present a case of acute adductor magnus muscle abscess (pyomyositis) with spread to adjacent thigh compartments via the perforators without iliopsoas muscle involvement. Due to the involvement of the entire thigh compartment, systemic antibiotic treatment alone was insufficient, whereas surgical drainage improved the clinical picture. The aetiological organism was S. aureus. Herein, we report the case of a patient who had primary pyomyositis, rather than a secondary type, that spread to the posterior and lateral aspect of the thigh through the second and third perforators, which pierce the adductor magnus muscle belly before entering the femur.
