A case of renal angiomyolipoma in a 38-year-old female is reported. The chief symptoms were abdominal pain and hypovolemia caused by massive retroperitoneal hemorrhage. A brief survey is given of the pathology, symptomatology, and the diagnostic possibilities with special reference to the radiologic diagnosis.

We describe the case of a previously healthy young woman admitted to hospital for abdominal pain and symptoms of shock. The preoperative diagnosis arrived at was polycystic kidney disease associated with ruptured angiomyolipoma. This combined pathology is pathognomonic of tuberous sclerosis; skin signs of the disease were also present in the patient, although undetected till then. The lack of neurological symptoms was an extraordinary finding. Cure is achieved at the cost of nephrectomy.

Renal angiomyolipoma (AML) is an uncommon, benign neoplasm of a hamartomatous origin that presents as multiple bilateral lesions occasionally associated with tuberous sclerosis, or as a single unilateral lesion. They are generally asymptomatic, and can manifest the following clinical triad: abdominal pain, palpable mass and hematuria. Retroperitoneal hemorrhage is a rare complication (9%). We report 3 cases of spontaneous rupture of renal AML with massive hemorrhage; two of these cases were associated with tuberous sclerosis. This complication was the presenting feature of renal AML in two cases. Radiologic diagnosis and management of this tumor type are highlighted.

We report on 5 patients who presented with acute onset of abdominal pain, a palpable mass, and a rapid decrease in hemoglobin. All 5 patients had been entirely free of urological symptoms until shortly before hospitalization. Spontaneous rupture of a kidney with an underlying pathological condition was found in all cases. In 2 cases the underlying lesion was renal cell carcinoma, while in the other 3 cases the lesion was a renal angiomyolipoma, a polycystic kidney and hydronephrosis secondary to UPJ obstruction, respectively. The importance of considering the possibility of spontaneous rupture of the kidney in the evaluation of cases of an acute abdomen is stressed.

We report a case of angiomyolipoma (AML) occurring in the renal sinus evaluated by intravenous urography (IVU), renal ultrasound (US), angiography, and computed tomography (CT). Imaging features of this lesion are identical to AMLs elsewhere, but preoperative diagnosis was complicated by the unusual occurrence of the tumor in this location in a patient with abdominal pain. Accurate preoperative diagnosis will allow tumorectomy or conservative management.

We report on a 25-year-old patient diagnosed as having Bourneville tuberous sclerosis with a giant angiomyolipoma 16 X 12 cm. in diameter, and two small angiomyolipomas in the left kidney, multiple asymptomatic angiomas in the right kidney and two 1 cm. diameter angiomas in the liver. The presenting features were intense left-sided abdominal pain of sudden onset, frank hematuria, acute anemic syndrome, nausea and vomiting. Patient work up included x-ray of chest, abdomen, and skull, bilateral renal arteriography and ultrasound were diagnostic of Bourneville tuberous sclerosis with multiple bilateral renal angiomyolipomas. The hematologic and hemodynamic compromise and the almost completely absent intact parenchyma in her left kidney did not permit a conservative surgical procedure and the patient was submitted to a left nephrectomy. The patient had the following characteristic features of Bourneville's disease: epilepsy, intracranial calcifications on CT, sebaceous adenomas on face, fibromas under nails of left hand and foot, bony lesions in the form osteosclerosis and chylous pleural effusion. Her intelligence level was normal and no optic nerve phakomas were observed. The literature on angiomyolipoma and Bourneville's tuberous sclerosis is reviewed. The importance of using ultrasound and CT in combination to diagnose and follow up renal angiomyolipomas is highlighted. Treatment of angiomyolipomas must be based on two parameters: symptoms and size. Symptomatic angiomyolipomas warrant angiographic work up and selective arterial embolization or the most conservative surgical procedure possible (enucleation, partial nephrectomy). Asymptomatic angiomyolipomas warrant CT and/or ultrasound examination every 6 or 12 months depending on size.

A 40-year-old housewife was found to have a renal mass on her left side through an ultrasonogram at the hospital during a medical check up. The patient had a dull pain in her left flank intermittently for three years. She had no personal or family history of stigmas of tuberous sclerosis. The mass showed a high echogenicity on the ultrasonogram and a low density (-84HU) on the CT scan. Preoperative diagnosis was reported as renal angiomyolipoma and an enucleation of the tumor was performed with CUSA. A statistical study was done on data taken from 429 cases of renal angiomyolipoma in the Japanese literature, including our case. The male to female ratio was 1 to 2.9. Thirty three percent of the cases were associated with tuberous sclerosis. The ratio of bilateral cases to unilateral ones was 1:4. The main clinical signs were abdominal pain, abdominal mass and gross hematuria. Nephrectomy was done in 71.0% of the cases, partial nephrectomy and enucleation in 13.7% and embolization in 2.2%. Through the composition of the CT scan and the ultrasonogram, preoperative diagnosis has become possible in many cases, so recently the ratio of nephrectomy has been decreasing. We think partial nephrectomy and enucleation compose the most effective therapy for renal angiomyolipoma.

We report a case of renal angiomyolipoma in a patient who, following normal delivery, presented with abdominal pain and acute abdomen with severe hemodynamic compromise that led to hypovolemic shock. Following diagnosis by emergency exploratory laparotomy, a left nephrectomy was performed. We underscore the difficulty involved in the diagnosis of acute abdomen from hemoperitoneum resulting from a ruptured angiomyolipoma, and highlight the rarity of this condition. Our patient was submitted to radical surgery because of vessel (hilum) invasion. The tumor was benign and no complications were observed. Patient work up eight years postoperatively revealed no local or systemic evidence of disease.

A 70-year-old woman with simultaneous unilateral renal angiomyolipoma and renal oncocytoma presented to the hospital with syncope and abdominal pain. Diagnostic studies indicated a left renal neoplasm consistent with renal cell carcinoma and a radical nephrectomy was performed. Histological examination of the resected specimen demonstrated the presence of the 2 unusual renal neoplasms.

This review summarizes the clinical and pathological findings of 52 cases of hepatic angiomyolipoma to discern and establish the most pertinent clinical and pathologic characteristics of the tumor. The disease was symptomatic in 60% of the patients. Abdominal pain or distress was the most common symptom, appearing in 37% of the patients, followed by malaise and upper abdominal mass or hepatomegaly. Of the 52 patients, only three (5.8%) showed associated tuberous sclerosis. Antemortem diagnosis of the tumor has been made with increasing frequency with the recent advent of computed tomography (CT) and ultrasound (US). The tumor was usually visualized as a hyperechoic mass by US imaging and as a low density mass less than -20 Housefield units by CT, and was hypervascular on angiography. The tumor was usually yellow to light tan, depending on the amount of fat tissue. Histologically, the tumor was characterized by an admixture of mature fat cells, blood vessels, and smooth muscle cells, with occasional foci of extramedullary hematopoiesis. The amount of smooth muscle component varied and often exhibited hypercellularity, pleomorphism with occasional bizarre giant cells, and moderate motitic activity. These features are considered conducive to an erroneous diagnosis of malignant tumor. However, since no malignant counterpart has been reported, it can easily be accurately differentiated histologically, if one is aware of the entity and can identify the three components of the tumor; blood vessels, smooth muscle cells, and fat. With regard to the histogenesis of angiomyolipoma, primitive mesenchymal cells around blood vessels may be the precursor cells.
