Retroperitoneal actinomycosis.
A 44-year-old man had an abscess involving the left psoas muscle and inferior pole of the left kidney associated with characteristic sulfur granules of actinomycosis. The patient was treated with surgical drainage and debridement and with intensive and prolonged penicillin therapy, resulting in a clinical cure and resolution of both the hydronephrosis and the retroperitoneal mass.
