The pyomyositis is a subacute deep muscle infection that can cause single or multiple intramuscular abscesses and is associated with systemic infections, diabetes mellitus, immunosuppressive therapy, AIDS and multiple myeloma. We describe a case of tropical pyomyositis with spinal involvement evolving to epidural abscess. The patient had a history of ankylosing spondylitis treated with immunosuppressive medications and presented direct injury in the right thigh prior to onset of symptoms. This article describes the unusual involvement of the spine in patients with tropical pyomyositis, with only one case reported in the world literature, highlighting the need for complementary methods of diagnostic investigation, for proper treatment and the possible complications of this disease. In conclusion, immunosuppressed patients with muscle pain should be investigated as to the tropical pyomyositis and the early diagnosis is crucial to the success of treatment.
