Renal vein thrombosis (RVT) is not an uncommon condition amongst patients with nephrotic syndrome or malignancy. Septic pulmonary embolism (SPE) is associated with risk factors such as intravenous drug use, pelvic thrombophlebitis, and suppurative processes in the head and neck. However, acute pyelonephritis is a rare cause of RVT and SPE. Case reports on RVT and SPE due to acute pyelonephritis are rare. In most of the earlier cases, patients had underlying conditions such as diabetes mellitus, renal carcinoma, calyceal stones, and hyperhomocysteinemia. We report a case of acute pyelonephritis complicated by RVT and SPE that occurred in a patient without any predisposing risk factors for thromboembolism. RVT and SPE were diagnosed using computed tomography and ventilation/perfusion scan. The patient recovered with antibiotics and anticoagulation therapy without any surgical interventions.
