title: [Case of xanthogranulomatous pyelonephritis complicated by simultaneous septic pulmonary embolism].
abstract: A 57-year-old man with fever-up and multiple nodules in the peripheral area of the lungs on the chest CT was referred to the department of respiratory medicine of our hospital for further examination. The whole body CT disclosed a space-occupying lesion in the left frontal lobe of his brain, an irregular mass in the left kidney, and swelling of paraaortic lymph nodes. A pathological diagnosis could not be made from the results of the bronchoscopic examination and percutaneous needle biopsy for the renal mass. Left nephrectomy and lymph node dissection were carried out because of possible renal malignancy with distant metastases. The renal lesion was diagnosed as xanthogranulomatous pyelonephritis histopathologically. After the nephrectomy, the multiple lung nodules disappeared spontaneously leaving scars in some lesions. Septic pulmonary embolism was highly suspected on the basis of the clinical course. The brain nodule also decreased in size significantly and is currently under careful surveillance.
