Hemodynamic Characteristics

Aneurysms within renal angiomyolipomas (AML) may rupture into the tumor or pararenal space. Transcatheter arterial embolization is the first-choice treatment to control bleeding. Here, we describe the use of coil embolization in two cases of spontaneous intratumoral hemorrhage with the hemodynamic characteristics of renal arteriovenous (AV) fistula in renal AML. In case 1, renal angiography showed several intratumoral aneurysms, one of which had ruptured into the tumor, resulting in the formation of an intratumoral hematoma. Blood flow within the hematoma was rapid and the blood was immediately returned to the systemic circulation through the left renal vein. In case 2, renal angiography showed that the rupture of an intratumoral aneurysm of a tumor-feeding artery had resulted in formation of an intratumoral hematoma and direct renal vein communication. No extratumoral hemorrhage was observed in either case. The hemodynamics of both hematomas resembled those of a high-flow renal AV fistula. The ruptured aneurysms were embolized with detachable and pushable coils (case 1) or pushable coils only (case 2). To our knowledge, this is the first report of successful embolization of AV fistula-like intratumoral hemorrhage in renal AML.

Benign Condition

Renal angiomyolipomas (AMLs) were first described in the early 1900s by Gravitz, but it was not until 1951 that they were named renal AML. These kidney tumours are rare, occurring in 0.13%–0.44% of the population. These mesenchymal tumours are composed of smooth muscle-like, adipocyte-like and epithelioid cells. Depending on the predominant cell population, it can be further subclassified into classic, epithelioid and AML with epithelial cyst. A 32-year-old woman presented with mild, intermittent, epigastric and right upper quadrant abdominal pain. Abdominal ultrasound revealed an incidental lesion within the inferior vena cava (IVC). A CT scan showed a lesion within the left renal vein extending into the IVC with 40% narrowing and a fat-containing mass in the lower pole of the left kidney of 15 mm suggesting an AML. Thrombectomy was performed. The specimen resulted positive for classic variant renal AML. Initial diagnosis is centred on imagining studies, based in fatty tissue concentration. The AML expresses melanocytic markers. This helps differentiate from renal cell carcinoma. Although AML is considered a benign condition, there is evidence of malignant transformation. Active surveillance is recommended for lesions <4 cm. Nephron sparing surgery is the procedure of choice. Nephrectomy is recommended if there is a high probability of malignancy. Mammalian target of rapamycin (mTOR) inhibitors have been proposed to be an alternative treatment.

Summary Objective: To increase awareness on the severe impact of the nutcracker syndrome in women with undiagnosed disease. Patients and methods: We reviewed the medical literature and analyzed six representative series with 73 patients with nutcracker syndrome. Women with left flank pain, dyspareunia, dysuria, dysmenorrhea, micro- or macrohaematuria and pelvic congestion symptoms, should be carefully investigated for evidence of meso aortic left renal vein compression. A good number of our colleagues do not believe in the existence of the nutcracker syndrome and send these patients in a long pilgrimage in search of someone who can help them to get relief to their pain. New and improved imaging techniques can assist in the diagnosis but retrograde reno-gonadal phlebography and renocaval gradient are the most reliable diagnostic tools. Results: Among an assortment of treatment techniques, renal vein transposition and endovenous stenting were the two most commonly used procedures. There are no long term studies on renal vein stenting in children and young adults. Its use in these cases should be carefully considered. The nutcracker syndrome may present with pelvic congestion symptoms and its diagnosis missed. The patient's age, severity of symptoms and haemo dynamic renal studies should guide the treatment. Conclusion: An increased awareness of the existence of the nutcracker syndrome may prevent many unfortunate undiagnosed women from spending many months and often years of suffering.

Introduction: Aneurysm of the communicating vein between the left renal vein and left ascending lumbar vein is extremely rare with only anecdotal reported cases. Unless detected and recognized promptly, this rare condition may give rise to severe bleeding in patients undergoing retroperitoneal surgery. It may also closely mimic enlarged retroperitoneal lymph nodes, paragangliomas, adrenal masses, or renal artery aneurysms. Case report: In this case study, we reported the imaging findings of this rare entity which was falsely diagnosed as enlarged retroperitoneal lymph node in an outside medical center, reported as to be consistent with metastatic disease, in a patient with newly diagnosed testicular cancer. Conclusion: The aneurysm of the communicating vein should be considered in the differential diagnosis in patients with testicular cancer and other disease processes where lymph nodes are commonly affected.
