The coronal sectional image of computerized tomography creates an image that is similar to an excretory urogram. It also provides more clearly delineated renal image and image of adjacent organs than an excretory urogram. Further more, the number, extent, and content of renal mats lesions used to discriminate density difference can be determined with relatively great accuracy. This image of computerized tomography is useful to understand and make a diagnosis of renal disease. Coronal sectional image of computerized tomography is more informative in evaluation of retroperitoneum space than conventional radiography. Recently we observed several cases of renal disease-renal cell ca, simple renal cyst, angiomyolipoma, retroperitoneal teratoma, pheochromocytoma, hydronephrosis which could be detected with coronal sectional image of computerized tomography.

Angiomyolipoma is a rare benign tumor and approximately 20 to 50% of patients with the diagnosis of angiomyolipoma have some or all of the other stigma of tuberous sclerosis. Patients with tuberous sclerosis tend to be younger, more likely to have multifocal and bilateral disease. Angiomyolipoma which is not associated with tuberous sclerosis mostly affects middle aged women. According to literature data, angiomyolipoma is very rare in child and almost exclusively associated with tuberous sclerosis. We report a case of 14 year-old girl who has a renal angiomyolipoma without clinical evidence of tuberous sclerosis.

A myolipoma is an extremely rare benign neoplasm, occurring most frequently in adults in the deep soft tissue of the abdomen or retroperitoneum. We experienced a case of an anal myolipoma occurring in a 30-year-old woman, and it was surgically resected. To our knowledge, this is the first reported case of a myolipoma arising from the anus, so such a possibility needs to be considered in the differential diagnosis.

One case of renal angiomyolipoma is reported in a 33 year-old house wife with right flank mass and pain, who was non-tuberous sclerosis, patient Diagnosis was made postoperately. This rare lesion posed a difficult differentiation from renal cell carcinoma. On the histologic examination, our case was found type 1 according to Smith's classification. The clinical, radiological and pathologic features are discussed.

During the last 9 years, 6 patients of renal angiomyolipoma were managed at Catholic University Medical College. All were unilateral and were not associated with tuberous sclerosis. Preoperative diagnosis were hypernephroma (4), angiomyolipoma and renal stone. All patients were treated with nephrectomy. 17 patients were reported in Korean literature previously. In the review of the 26 cases (23 pts.), 16 cases were diagnosed as angiomyolipoma preoperatively and other as hypernephroma(9) and renal stone(1). Almost all cases(22) were managed with nephrectomy and only 4 cases were managed with conservative treatment (arterial embolization or observation).

Although the excretory urogram, retrograde pyelogram, renal angiogram and ultrasound studies provide formidable competition in renal imaging, CT has advantages over each of these techniques and can provide unique and vital information in evaluating selected renal diseases. CT provide a cross-sectional view of the anatomy, thus delineating more clearly the renal margins and adjacent organs. CT imaging is not dependent on renal function and more easily recognized as a true anatomic portrayal, Furthermore, to discriminate density differences, the nature of renal masses may be determined. Recently we experienced several cases of renal diseases, confirmed with CT which was particuly useful in making in accurate diagnosis than other urologic examinations. Surgery, clinical follow-up and repeated radiologic examinations confirmed the accuracy of CT and there were no cases in which medical of surgical management was inappropriately guided by CT. herein a series of renal disease-polycystic kidney with bilateral radiolucent pelvic stones, angiomyolipoma, renal infarction, renal injury and renal pelvic transitional cell carcinoma were presented and the diagnostic advantages of CT for evaluation of renal diseases were discussed with a review of the literatures.

We report a case of lipoleiomyoma which arose in retroperitoneum and presented with progressively distended abdomen in a 56-yr-old woman. The tumor was well encapsulated and consisted of two components, benign smooth muscle cells and mature adipose tissue without any atypia. It is likely to be mistaken as extrarenal angiomyolipoma, well-differentiated liposarcoma and leiomyoma with fatty change. We review the histologic characteristics of previously reported myolipoma and describe essential points of differential diagnosis.

Renal angiomyolipomas are uncommon benign neoplasms composed of mature adipose tissue, thick walled blood vessels and smooth muscle in varying proportions. Accurate preoperative diagnosis of renal angiomyolipoma is essential if conservative resection or angiographic embolization is to be used. In recent years, abdominal computerized tomography (CT) and renal ultrasonography have resolved the diagnostic dilemma, making detection of angiomyolipomas possible in almost all cases. Recently, we performed selective renal angioembolizations in 3 patients (2 females, 1 male). After followup period of 6 months to 1 year, all patient got better in clinical symptoms. In two of them the lesions decreased in size on followup CT but one patient showed suspicious malignant change and we performed the exploration to rule out renal malignancy. In our opinion, it is appropriate to perform the selective renal angioembolization for initial treatment of renal angiomyolipomas.
