Renal actinomycosis—An unusual cause of a renal abscess

We report an uncommon case of a renal abscess with actinomycosis infection in a 59-year-old female, who had stage 5 chronic renal disease and type 2 diabetes mellitus. Abdominal computed tomography revealed an enlarged right kidney infiltrated with multiple cyst-appearing lesions of homogeneous, low density contents. A nephrectomy was performed because of persistent toxic signs after treatment with antibiotics. The patient was well 1 year following surgery. We also review previous cases reported in the literature.
