“…Given the benign nature of AML, renalpreserving treatment modalities such as nephron-sparing surgery (NSS) or selective renal artery angioembolization (SAE) are preferred [7]. Only 14 cases of AML involving or originating from the renal sinus have been previously reported [1,5,[9][10][11][12]. The diagnosis and management of a fat-containing tumor of the renal sinus may be challenging due to the inherent difficulty in differentiating them between malignant and benign fatty lesions in an anatomic space that normally contains fat.…”

“…AML most often originate from the renal parenchyma and other abdominal organs, such as liver, spleen, fallopian tube, and lymphatic tissue [2][3][4]. An AML that originates from the renal sinus rather than the renal parenchyma is extremely rare and is therefore difficult to differentiate from other fatcontaining masses, such as lipomatosis, lipoma, and liposarcoma [1]. It is important to distinguish between exophytic AML and liposarcoma within the perinephric space because there are obvious substantial differences in clinical management.…”

The case of a 63-year-old woman with a relatively rapidly growing angiomyolipoma (AML) originating from the right renal sinus is presented. The tumor had enlarged to more than fivefold in volume (7.4 × 6.7 × 10.1 cm) in the 7 years following its detection (5.6 × 3.4 × 4.6 cm) and had significantly pushed aside the duodenum and the inferior vena cava. The tumor was surgically resected together with the right kidney, and pathological examination revealed AML originating from the renal sinus. An AML involving or originating from the renal sinus is exceedingly rare; only 14 cases have been reported. Rapidly growing AMLs of the renal sinus are difficult to differentiate from liposarcoma because of similar findings in imaging studies. It should be noted that AML of the renal sinus can be a differential diagnosis of retroperitoneal fatty mass. Furthermore, an enlarged AML in the renal sinus may push aside other organs, such as the ileum, pancreas, and major vessels. Clinicians should determine whether these patients should be placed under active surveillance or be treated with invasive measures, such as radical nephrectomy.

“…Renal angiomyolipoma can protrude to the renal hilus and may have a large lipomatous component, but it usually appears in patients with a history of tuberous sclerosis [9]. Although exceptional cases arising from the renal sinus have been reported [10], all these tumors are generally located in intrarenal or extrarenal areas outside the sinus, whereas RLK originates in the sinus and hilus and extends to the intrarenal and perirenal spaces. Absence of calculi and preserved renal function are also important differentiating features.…”

“…An interesting feature is the predominance of right-sided lesions, apparently representing nearly 80 % of the solitary tumors (1,14). As many as 25 % of these tumors may arise in an extrarenal location, including the renal sinus (4,14).…”

Several fatty tumors of the kidney and adrenal gland were evaluated by gray scale ultrasound. An extremely dense echogenic pattern was common to all lesions. There were three solitary angiomyolipomata (renal hamartoma), a presumed diffuse hamartomatous involvement of the kidney in a patient with tuberous sclerosis, and one myelolipoma of the adrenal gland. This marked echogenicity is thought to be a feature of fatty tumors and enables relatively specific preoperative diagnosis of these lesions, all of which are benign. With regard to renal angiomyolipoma, this assessment may allow conservative treatment and preservation of functioning renal tissue.
