The Incidental Finding of Horseshoe Kidney in a 31-Year-Old Male Patient with Lupus Nephritis

We describe the case of a 31-year-old-male who presented with an acute flare of SLE, gross hematuria, left lumbar pain, fever, and burning micturition. He had a history of systemic lupus erythematosus, hypertension, myocardial infarction, and weight loss. Radiological examinations with ultrasound and computed tomography imaging revealed fusion of the lower poles of the kidneys rotated at the renal hilum forming a U-shape, in addition to a definite diagnosis of lupus nephritis. The patient subsequently underwent three sessions of plasmapheresis. The final diagnosis was consistent with a co-morbidity of horseshoe kidney and lupus nephritis in the adult male patient who was discharged and advised regular follow-up.
