Pyomyositis (PM) is an uncommon cause of acute bacterial infection occurring in skeletal muscle. This disease is rare in non-tropical areas, and PM caused by Mycobacterium is very rare in a non-immunocompromised person. The presence of temporal area swelling may lead to a differential diagnosis toward more common pathologies, such as a complication of mastoiditis or a neoplasm of the temporal area. This article describes a case of tuberculous pyomyositis in a non-immunocompromised woman, the diagnosis of which was confirmed by sonographically guided fine-needle aspiration.
