“…The previous case resulted in an open radical nephrectomy on a patient who had severe recurrent flank pain as a result of trauma 5 years earlier. 2 In contrast, our case illustrates an asymptomatic lesion treated with renal-sparing surgery. Our patient's renal infarct likely arose from emboli showered from his transplanted heart.…”

“…standing fibrosis and calcifications and create confusion in differentiating them from other renal masses, especially RCC. 2 The presence of penetrating vessels from the capsular plexus spares the cortex from infarction, resulting in the classical cortical rim sign. 5 Anticoagulant therapy may lead to resolution of the infarct, and the mass effect may disappear.…”

A 55-year-old man presented with an exophytic asymptomatic right renal lower-pole mass simulating a renal-cell carcinoma. He underwent retroperitoneoscopic partial nephrectomy, and histopathologic examination revealed a chronic renal infarct with calcifications. We report this case to stimulate the inclusion of focal chronic renal infarct in the differential diagnosis of asymptomatic renal masses, as well as to advocate a minimally invasive approach to appropriate renal lesions.

“…Therefore, nephrectomy was performed. Renal sinus tumors would remain undiagnosed unless the possibility of hemangioma via percutaneous or intraoperative biopsy is excluded ( 2 ). In the current study, one patient was diagnosed with a benign tumor based on the intraoperative biopsy results and underwent excision of the tumor, whilst simultaneously, preserving the kidney.…”

The aim of the present study was to investigate the clinical characteristics and management of primary renal sinus tumors. We retrospectively analyzed three cases of primary renal sinus tumors. The first patient was a 33-year-old man who presented with right flank pain for 6 months. Based on the imaging results, the patient was diagnosed with renal sinus tumor. The second case was a 34-year-old woman who presented with sudden lumbago in the right flank for 3 days. The imaging results confirmed the diagnosis of right renal angiomyolipoma. The third case was a 55-year-old woman with flank pain, which had persisted for 1 year. The imaging tests revealed lipoma of the left renal sinus. All three cases underwent surgical procedures. The first case was diagnosed with benign angioleiomyoma following pathological analysis. During surgery, the tumor was ablated and the kidney was spared. The second case was scheduled for tumor enucleating, but a nephrectomy was performed due to serious hemorrhaging and a damaged renal pelvis. Pathological analysis identified angiomyolipoma. The third case was scheduled for lipoma enucleating; however, nephrectomy was performed as the tumor encapsulated the renal vascular pedicle. Pathological analysis revealed lipoma. In the three cases, no relapse over 3 years, 10 months and 4 years of follow-up, respectively, was observed. In addition, this review examined previous literature and concluded that the occurrence of tumors in the renal sinus is rare and the majority of such tumors are benign. Furthermore, cases are easily misdiagnosed as renal pelvic tumors. Computed tomography, magnetic resonance imaging and intravenous urography are the best imaging examination methods for differential diagnosis. In conclusion, surgery is the usual approach for the treatment of renal sinus tumors and radical nephrectomy should be performed for malignant tumors.

“…Most are located in the pelvis or pyramids and only rarely are the capsule or cortex involved [80]. When seen near the renal pelvis or sinus, they can mimic primary lesions of the urothelium such as transitional cell carcinoma [89]. Renal hemangiomas tend to be 1-2 cm or less in size, although lesions ranging between 0.5 and 10 cm have been reported [80,82].…”

“…These lesions are nonencapsulated [84]. Lesions can manifest at any age, with a peak incidence between 30 and 40 years of age [89]. Because of their common location near the collecting system, patients may present with intermittent macroscopic or microscopic hematuria or with renal colic.…”
