A 59-year-old male was admitted to our clinic for further examination of the calcified renal cyst discovered incidentally on medical workup elsewhere. CT showed a left renal cyst associated with calcification. Ultrasound-guided puncture of the renal cyst was not successful because of thickness of the cystic wall. Renal angiography showed hypervascularity of the cystic wall. Association of renal cell carcinoma could not be ruled out, therefore the exploration was performed. Histological examination revealed benign renal cyst with calcification. A 27-year-old male presented with the chief complaint of left flank pain. Following examinations by US, CT and MRI, a renal cyst associated with renal cell carcinoma was highly suspected. Subsequent exploration revealed cluster of cysts with a yellowish lesion a few mm in diameter. Frozen section revealed no malignancy, and cystic fluid was not hemorrhagic. Therefore as many cystic walls as possible were removed without nephrectomy. Histological examination of the permanent specimen revealed renal cell carcinoma. Renal cyst associated with renal cell carcinoma was regarded as rare clinical entity, but such cases are reported in increasing number in recent years. We report such cases and review the pertinent literature in this paper.

Renal AML are rare benign tumors of the kidneys consisting of fat tissue intermixed with thick-walled blood vessels and smooth muscle. Due to the easy access to modern imaging techniques more and more AML are detected incidentally during diagnostic evaluation of common urological disease before getting symptomatic (mostly flank pain, hematuria). The presence of a highly echodense renal mass on ultrasound and the detection of even small amounts of fat in CT usually allows to establish the diagnosis of AML. If these procedures give still equivocal results, angiography and MRI may become necessary. When report a case of a patient with AML where all the imaging techniques including magnetic resonance were nonconclusive. The correct diagnosis could only be established by histological examination after surgical resection. Indeed, the presence of a large hematoma had masked all the characteristic features of AML in this case.

In a 54-year-old patient who entered the hospital because of flank pain of the left side, a prevesicular urethral calculus was found. On further investigation hypercalcaemia and hypophosphataemia were detected, possibly indicating hyperparathyroidism. When an ultrasound of the abdomen was made to exclude hydronephrosis, a tumor in the pancreas was found. The result of the fine needle biopsy of this tumor showed a neuroendocrine tumor. The examination of neuroendocrine parameters was without any reference to an active secreting process. On suspicion of a multiple endocrine neoplasia, a MRI of the hypophysis was made which showed no adenomatous alterations. The examination of the neuroendocrine parameters were without any reference to an active secreting process of the hypophysis, too.

The patient, a 45-year-old male, complained of left flank pain and fever. CT revealed bilateral adrenal tumors, in which MRI disclosed inhomogeneous signal intensity with low signal intensity rim. Arteriography demonstrated bilateral adrenal tumors with moderately rich tumor vessels.

A case of bilateral renal angiomyolipoma without tuberous sclerosis is reported. A 49-year-old woman was admitted to the general practitioner with a sudden onset of severe left flank pain. An excretory urogram and ultrasonogram revealed an enlargement of the left kidney. She was subsequently referred to our clinic for further investigation and treatment. Computed tomographic scan and magnetic resonance imaging using Tl-weighted image showed several tumors with a fatty, dense area in the bilateral kidney. An arteriogram demonstrated a hypervascular renal mass with aneurysms in her left kidney. Diagnosis of bilateral renal angiomyolipoma was confirmed by percutaneous needle biopsy. Superselective embolization of the tumor was successfully performed, preserving normal renal tissue. Gelatin sponges containing Carboquone (CQ sponge) were used as embolic material. Angiomyolipoma has become relatively easy to diagnose by CT, ultrasound, MRI and so on. However, there are some cases of angiomyolipoma which are indistinguishable from renal cell carcinoma using these modes of testing. Therefore, in selecting a conservative management, we indicated that percutaneous biopsy or open biopsy should be done to confirm the results of the above procedures. Moreover, therapeutic embolization for angiomyolipoma was concluded to be very useful.

Renal fossa heterotopic splenic tissue is characteristically asymptomatic and is usually an incidental finding that has been reported to mimic renal or adrenal tumors. However, symptoms related directly to the splenic tissue do occur. We present an unique case with simultaneous occurrence of an accessory spleen and splenosis which were diagnosed following intentional radiological investigations conducted to evaluate flank pain which was probably related to the presence of the heterotopic spleens. CT complemented by isotopic liver-spleen scan is the radiological modality of choice in the diagnosis of renal fossa splenosis. However, MRI may significantly contribute to the evaluation by accurate delineation of blood supply and surgical separation planes.

A 48-year-old male experienced sudden pain in the right flank and macrohematuria with subsequent repeated episodes of painless macrohematuria. In the radiological work-up, CT was interpreted as inflammatory enlargement of the right kidney and MRI diagnosed renal vein thrombosis. There was some suspicion that there might be a malignancy. Five months later the patient had to be admitted to the hospital, because of increasing flank pain, desiccation and general signs of inflammatory disease. Radiological changes compatible with pulmonary metastases were found. Biopsy of enlarged mediastinal lymph nodes revealed undifferentiated carcinoma. Because of the expression of Cytokeratin primary urothelial carcinoma was suspected. The patient then deteriorated rapidly. No further specific therapy could be carried out. Death was chiefly caused by respiratory insufficiency 5 months after the first episode of pain and 1 month after admission. Autopsy revealed a poorly differentiated urothelial carcinoma of the right renal pelvis, with extensive carcinomatous angiomatosis and metastases to the left kidney, lungs, and regional and mediastinal lymph nodes. Independently of the carcinoma, both kidneys also showed interstitial nephritis, papillary necrosis and capillarosclerosis, compatible with analgesic-user kidney ("phenacetin kidney") in the absence of a corresponding history.

A 73-year-old man was admitted to Toyama Red Cross Hospital, because of productive cough and right flank pain. His chest X-ray film and computed tomography (CT) showed pleural effusion and a mass shadow in the right lung area. On CT vessels and bronchi were seen curving toward the mass (comet tail sign), suggesting rounded atelectasis. Transthoracic lung biopsy under CT and echo guidance revealed suppurative pleuritis. MRI also showed the comet tail sign. Moreover, in the lesion, curling hypointense lines were observed on various slices. We describe how MRI facilitates the diagnosis of rounded atelectasis.

A 79-year-old female with hepatocellular carcinoma with portal invasion and right adrenal gland metastasis was treated by low dose UFT (200 mg/day). Two months after the initiation of UFT administration, CT scan revealed marked contraction of the primary liver tumor and right adrenal metastasis. Serum AFP and PIVKA-II were also reduced, and right flank pain disappeared. Six months later, CT scan and MRI study were performed. The findings of liver and metastatic lesion were the same as in the earlier study, and the liver function and the patient condition were well controlled. This case is probably rare, but suggestive in the choice of treatment for advanced hepatocellular carcinoma.

A patient is described in whom retroperitoneal fibrosis manifested itself by bleeding from ruptured varices and pain in the left flank and lumbar region. The clinical diagnosis was confirmed by axial computerized tomography and MRI, while the histology from a mesenteric biopsy taken during splenectomy was considered insufficiently consistent with the diagnosis of retroperitoneal fibrosis. Treatment with prednisone resulted in relief of lumbar and flank pain a well as in prevention of further digestive tract hemorrhage. A review of the literature since 1966 shows 16 articles describing the association of retroperitoneal fibrosis and portal hypertension manifesting itself by hemorrhage from bleeding varices.
