1/19. Arteriovenous shunting in a giant renal angiomyolipoma. A rare condition.We report a case of a 33-year-old woman with tuberous sclerosis and bilateral angiomyolipomas. She suffered from acute left flank pain due to retroperitoneal haemorrhage. During renal arteriography an arteriovenous shunting was found in the left tumour. angiomyolipoma is a rare cause of angiographically demonstrable arteriovenous shunting.- - - - - - - - - - ranking = 1keywords = flank pain, flank (Clic here for more details about this article) |
2/19. Traumatic rupture of angiomyolipoma: a case report.OBJECTIVE: To describe a case of traumatic rupture of renal angiomyolipoma (AML). methods: The images and clinical data of the present case are presented. RESULTS: A rare case with exuberant clinical presentation of a perirenal hematoma resulting from traumatic rupture of renal AML is presented with a brief review of the role of ultrasound (US) and body-CT in the diagnosis of this pathology and its complications. CONCLUSIONS: Whenever there is a collection detected by US in the various anatomic renal spaces, in a patient with flank pain and low hemoglobin shortly after abdominal trauma, it is advisable to perform abdominal CT and search for a hematoma. Small amounts of fat, detected by US and body-CT, may lead to the diagnosis of an underlying AML that can rupture, even in the case minor forces are applied to the kidney.- - - - - - - - - - ranking = 1keywords = flank pain, flank (Clic here for more details about this article) |
3/19. Various radiological appearances of angiomyolipomas in the same kidney.A 21-year-old woman with tuberous sclerosis presented with abdominal distension and flank pain. Imaging studies, including CT and MR imaging, revealed bilateral renal mass lesions, containing fat and suggesting the diagnosis of tuberous sclerosis. However the imaging characteristics of one of these lesions differed from the others with no radiologically detectable fat tissue in this solid lesion suggesting renal cell carcinoma. Histopathological examination of this lesion in the left kidney revealed an angiomyolipoma within minimal fat tissue. The radiological diagnosis of angiomyolipomas with minimal fat tissue remains difficult and the differential diagnosis is discussed.- - - - - - - - - - ranking = 1keywords = flank pain, flank (Clic here for more details about this article) |
4/19. Lymph nodal involvement by renal angiomyolipoma.angiomyolipoma of the kidney is a clonal neoplasm, apparently part of a family of neoplasms derived from perivascular epithelial cells. A 40-year-old woman presented with right flank pain and an otherwise non-significant medical history. An abdominal computed tomography scan revealed an 18 cm solid mass in the mid-portion of the right kidney and multiple perihilar lymph nodes. Presumptive diagnosis was renal cell carcinoma. Right radical nephrectomy and a perihilar lymph node dissection was performed through a Chevron incision for the anticipated diagnosis of renal adenocarcinoma. The renal tumor was diagnosed as angiomyolipoma and a component was identified pathologically in a dissected lymph node. There was no evidence of tumor recurrence in the follow-up period of eight years. The consensus from other studies suggests that this phenomenon is a manifestation of the multicentric nature of angiomyolipoma, rather than due to metastasis. Genetic studies may resolve this question in the future.- - - - - - - - - - ranking = 1keywords = flank pain, flank (Clic here for more details about this article) |
5/19. Laparoscopic wedge resection of a renal mass in a solitary kidney.Laparoscopic radical nephrectomy has gained acceptance as a viable means of managing renal neoplasms. Partial nephrectomy has traditionally been performed through a flank or transabdominal incision, with its attendant morbidity and required hospitalization. Laparoscopic renal-sparing surgery may be more technically demanding, but remains beneficial to the patient if performed with adherence to oncological principles. We present a case of laparoscopic renal-sparing surgery in a patient with a renal mass in a solitary kidney. We discuss the technical and oncological challenges of this approach.- - - - - - - - - - ranking = 0.11645596226047keywords = flank (Clic here for more details about this article) |
6/19. Nephron-sparing surgery in multiple bilateral angiomyolipomas.We report on a 17-year-old white woman with multiple bilateral renal angiomyolipomas (AMLs) in the absence of tuberous sclerosis. Multiple hyperdense lesions were detected in both kidneys by sonography. A computed tomography (CT) scan confirmed mainly fatty tissue. Sparing as much functional tissue as possible, eight AMLs of the right kidney were resected. The largest removed tumour measured 7 x 4 x 2.4 cm. Renal function was completely preserved. An AML is a benign, generally unilateral renal tumour. Treatment is necessary in cases of flank pain, spontaneous bleeding, obstruction by tumour growth and tumours exceeding 4 cm in diameter. patients who present are often symptomatic due to pain, retroperitoneal bleeding or haematuria. An AML occurs either sporadically or in association with tuberous sclerosis. Bilateral or unilateral multiple AMLs are rare.- - - - - - - - - - ranking = 1keywords = flank pain, flank (Clic here for more details about this article) |
7/19. Hemorrhagic angiomyolipoma and tuberous sclerosis complex: a case report.tuberous sclerosis was first described in 1862 by von Recklinghausen. Since then there have been many advances in our understanding of the diagnosis, pathogenesis, and treatment of this disease complex, especially after it was characterized genetically. While many patients who have tuberous sclerosis present with the classic triad of mental retardation, seizures, and facial "adenoma sebaceum," most do not because of its variable penetrance. The diagnostic criteria have been revised to include patients with tuberous sclerosis who do not match the classic pattern. Here we describe a 44-year-old female without a prior diagnosis who did not have the classic triad but who presented with flank pain. Hemorrhagic angiomyolipoma was diagnosed by computerized tomography scan and she was treated by an embolization procedure. We review tuberous sclerosis and underscore the need to consider this diagnosis for the following reasons: 1. it is not uncommon (slightly more than one in 6,000 live births); 2. its presentation is protean; 3. once the diagnosis is made, search can be made for associated findings that may lead to additional morbidity if not carefully managed, e.g., if an angio-myolipoma is diagnosed, it can be followed and possibly treated; and 4. owing to its autosomal dominant pattern of inheritance, members of the family can be screened appropriately.- - - - - - - - - - ranking = 1keywords = flank pain, flank (Clic here for more details about this article) |
8/19. angiomyolipoma with a caval thrombus.We report the case of a female patient presenting with flank pain. Abdominal ultrasound revealed a tumor of 8 cm in diameter. After abdominal computerized tomography, the tumor was classified as angiomyolipoma with a tumor thrombus in the inferior vena cava. After nephrectomy, the diagnosis was confirmed histologically. To our knowledge, this is the 11th case of a renal angiomyolipoma extending into the vena cava.- - - - - - - - - - ranking = 1keywords = flank pain, flank (Clic here for more details about this article) |

10/19. association of angiomyolipoma and oncocytoma of the kidney: a case report and review of the literature.AIM: The association between renal carcinoma and angiomyolipoma is rare. Only 14 cases have been reported in the literature. The purpose of this paper is to present an additional case and review the literature on this association. PATIENT AND methods: A healthy 42 year old woman was found to have a left flank mass incidentally when she presented for a Papanicolaou smear. The computerised tomography scan revealed a left lower pole renal mass consistent with a renal cell carcinoma. A nephrectomy was performed and the patient recovered uneventfully. The nephrectomy specimen was processed routinely. In addition to haematoxylin and eosin staining, immunohistochemistry for CAM 5.2, vimentin, CD34, antismooth muscle actin, and HMB45 was carried out. Transmission electron microscopy was also performed. RESULTS: Macroscopically, the lower pole of the kidney contained a well circumscribed, non-encapsulated, tan coloured tumour with a large area of central haemorrhage measuring 10.5 cm. In addition, there was a 0.4 cm poorly circumscribed unencapsulated yellow nodule adjacent to the tumour. Microscopically, the larger tumour showed characteristic features of an oncocytoma. Numerous mitochondria were seen on electron microscopy. The smaller yellow nodule was an angiomyolipoma. CONCLUSIONS: This paper presents an additional case of oncocytoma associated with angiomyolipoma. Of the 15 cases described in the literature, three were associated with the tuberous sclerosis complex, all from a single study. In tuberous sclerosis, angiomyolipomas are more commonly associated with renal cell carcinoma. If angiomyolipomas are found incidentally in nephrectomy specimens together with other tumours, it is important to exclude tuberous sclerosis retrospectively.- - - - - - - - - - ranking = 0.11645596226047keywords = flank (Clic here for more details about this article) |
