Pyomyositis is an acute bacterial infection of skeletal muscles arising from transient bacteremia, commonly associated with Staphylococcus aureus. Owing to its higher frequency in tropical regions, the infection has earned itself the title of “tropical pyomyositis”. However, it must be mentioned that the disease is no longer restricted to tropical regions, and its frequency is increasing worldwide. Obturator pyomyositis mimics other common infections involving this area like septic arthritis. Indeed lack of awareness of pyomyositis commonly leads to delays in both diagnosis and adequate treatment. Magnetic resonance imaging (MRI) is the best tool for diagnosing pyomyositis. Treatment consists of bed rest, antibiotics, percutaneous drainage, as well as surgical intervention, depending on diagnostic delay and extension of the infection.
