Urinary tract complications, manifesting as leakage or obstruction, generally occur in 3.0~13% of renal recipients. Most complications occur at the ureterovesical anastomosis and are secondary to technical causes and ureteric ischemia. Ultrasound and computed tomographic images are described in a recipient who underwent oversea deceased donor renal transplantation and presented with recurrent ureteral obstruction and hydronephrosis secondary to combination of unusually located transplant kidney, long-coiled ureter, ureteric compression and ischemia of the transplant ureter.

Tufted angioma is a rare benign vascular neoplasm that usually occurs in children. It appears as an erythematous, purplish, indurated papule or plaque on the trunk or neck. Although it can have variable clinical manifestations, the annular or serpiginous configuration of lesions resembling tinea infections has rarely been reported. A 47-year-old woman presented with an erythematous plaque enlarging by peripheral extension to form polycyclic or serpiginous figures on her left chin and buccal cheek for 7 months without any subjective symptoms. Tinea faciale was considered as the initial clinical diagnosis, but repeated KOH tests were all negative; therefore, skin biopsy was performed. Histopathology revealed discrete circumscribed foci of capillaries scattered throughout the dermis showing a cannon ball appearance, compatible with tufted angioma. Clinical features showed considerable improvement after 2 sessions of intense pulsed light and pulsed-dye laser (5 repetitions) without any complications. Herein, we report a rare case of polycyclic variant of tufted angioma, which developed in a woman in her 5th decade.

PURPOSE: To evaluate the radioloic findings of malignant retroperitoneal fibrosis. MATERIALS AND METHODS: Post-contrast CT (n=9) and urographic (n=7) findings of nine patients with malignant retroperitoneal fibrosis were retrospectively analyzed. Primary tumors were found to be advanced gastric cancer (n=6), early gastric cancer (n=1), breast cancer (n=1), and cervical cancer (n=1). We analyzed CT findings with regard to the site of soft tissue lesion, ureteral involvement, the presence or absence of hydronephrosis, and distant metastasis. The level and length of ureteral involvement, presence or abscence of ureteral stenosis, and ureteral displacement as seen on urography, were analyzed. RESULTS: On CT scans, enhanced soft tissue lesions (mass, 5 cases; plaque, 4 cases) encircling the abdominal aorta and IVC were noted in all cases. Thickening of the ureteral wall (n=8), hydronephrosis (n=9), and enlarged lymph node (n=5) were also seen. On urography, irregular stenosis and medial displacement of ureters from level L2 to S2 were noted in all cases. The length of ureteral involvement was 4-6.5cm. CONCLUSION: The common CT findings of malignant retroperitoneal fibrosis were enhanced soft tissue lesion encircling the abdominal aorta and IVC, hydronephrosis, and thickening of the ureteral wall. On urography, ureteral stenosis and medial displacement were seen.

PURPOSE: To determine the value of high resolution ultrasonography (US) for the detection of hepatocellular carcinoma in the HBx transgenic mice. MATERIALS AND METHODS: Forty-two HBx transgenic mice aged 8-20 (mean, 14) months underwent high-resolution ultrasound using a 10 -12 MHz linear transducer. US findings indicating the presence or absence, number, size and echogenicity of each hepatic tumor were analyzed, and inaddition, color or power Doppler US was used to analyse tumoral vascularity. In each animal, sacrificed less than five hours after US examination, sonographic and pathologic findings were correlated. RESULT: On gross pathologic examination, 20 hepatocellular carcinomas measuring 1.5 -15 (mean, 4.7) mm in diameter were found in 16 mice; US revealed that 17 of the tumors were homogeneous hypoechoic nodules. With regard to tumor detection, sensitivity was 85%, specificity 96%, positive predictive value 0.944, negative predictive value 0.897, and overall accuracy 90%. Doppler US revealed that in three nodules, intratumoral vessels were present. Inthe other 26 mice, gross examination showed that no mass was present; microscopically, however, four nodules measuring 0.3 -1.2 mm were found in four of these animals. Tumoral vascularity detected by color Doppler US corresponded to the intratumoral vessel within the nodules. One peritoneal nodule, confirmed as a metastatic tumor, was found at the greater omentum. CONCLUSION: In HBx transgenic mice, high-resolution US is valuable for the detection of hepatocellular carcinoma.
