A case of clear cell adenocarcinoma arising in the female urinary bladder, which is accompanied by endometriosis of the urinary bladder and the uterus, is reported. The carcinoma protruded into the vesical lumen as a fungating mass, and had a tubulocyotic pattern. The tumor cell had intracytoplasmic glycogen and electron microscopically short microvilli on their surface, resembling clear cell acenocarcinoma of the female genital tract including ovary. This is the fourth case report of clear cell adenocarcinoma complicating vesical endometriosis, and may support the view that clear cell carcinome arises from endometriosis which, in turn, from the Mullerian remnant.

A case of xanthogranulomatous oophoritis is presented in a patient who had a 3-month history of intrapelvic mass protruding into the vagina. The sonographic findings are a well defined mass shadowing lower echogenicity than the echo of the uterus at the posteosuperior aspect of the uterus. The CT findings are an enhancing solid mass with central necrosis containing a multiseptated cystic component.

Secondary osteoarthritis of hip joints is a common disease and is frequently followed by chronic sublexation and dislocation. Twenty four case of the secondary osteoarthritis associated with chronic subluxation and dislocation of the hip joints were evaluated with plain radiography and computed tomography. We retrospectively analyzed 1) the ossification and calcification of the acetabular labrum, 2) the thickeness of the quadrilateral plate of the ilium, and 3) anteroposterior diameter of the acetabulum. The changes of the hip joints in subluxation (n=14) revealed ossification of the acetabular labrum in 12 cases (86%), thickening of the quadrilateral plate of the ilium in 11 cases (78%) but anteroposterior diameter of the acetabulum was not changed. The changes of the hip joints in dislocation (n=10) revealed no evidence of the ossification of the acetabular labrum, thickening of the quadrilateral plate of the ilium in 10 cases (100%) and decreased anteroposterior diameter of the acetabulum. We conclude that CT findings of subluxation and dislocation of the hip joints can be helpful in the evaluation of the secondary osteoarthritis of the hip joints.

PURPOSE: Pigmented villonodular synovitis (PVNS) is a rare soft tissue tumor, which usually arises in larger joints, such as the knee. It has a high recurrence rate after surgical treatment. The purpose of this study is to evaluate and analyze the clinical results of diffuse-type pigmented villonodular synovitis cases that were treated with open total synovectomy. MATERIALS AND METHODS: Between 1994 and 2006, 21 patients who had diffuse-type pigmented villonodular synovitis were selectively reviewed. Among the 21 cases studied, 14 patients presented at the knee, 5 at the ankle, and 2 at the shoulder and elbow. The mean follow up period was 5.5 years (range, 36-157 months). The average age of the patients was 34 years consist of 7 men and 14 women. Clinical outcomes were analyzed retrospectively, including range of motion and complications. RESULTS: Open total synovectomy and adjuvant electrocautrization were done in all cases except one. During the regular follow-up period after the surgery, two patients showed symptoms of recurrence. After re-operation, only one case was pathologically confirmed as a recurrence. The patient who had partial synovectomy and the other patient who had second operation due to recur rence received additional radiation therapy. Clinical outcome scores were improved in every aspect (p<0.0001). 2 out of 14 Patients who had pigmented villonodular synovitis at the knee developed stiff knee after the surgery. CONCLUSION: After the open total synovectomy with electrocautrization, a low recurrence rate and satisfactory clinical outcome was achieved, observed in a minimum of 3 years of follow-up.

The magnetic resonance images (MRI) of 30 patients with surgically or biochemically confirmed pituitary adenomas (20 macroadenomas, 10 microadenomas) were retrospectively evaluated. Ten patients had hyperprolactinemia, another eight had acromegaly, another eight had nonfunctioning adenoma and four had Cashing disease. The examination were performed at a 1.5-T superconducting MR system using a multisection spin-echo technique with 3mm-thick sections and a 256×224 matrix. TI weighted sagittal and coronal images were obtained before and within 30 minutes after the administration of Gd-DTPA (0.1mmol/kg). Analysis of the MRI was focused on the signal intensity and enhamcement patterns of the pituitary adenoma before and after Gd-DTPA administration. Compared with endocrinologic diagnosis, macroadenoma showed heterogeneous enhacement in 55%, rim enhancement in 35% and homogeneous enhancement in 10%, Conclusively, the enhancement patterns of the pituitary adenoma did not correlate with the subtypes made according to hormone production.

Paroxysmal nocturnal hemoglobinuria(PNH) is a rare, acquired disease involving multiple hematopoietic lines. Characteristics of PNH are intrinsic hemolytic anemia, iron deficiency anemia and venous thrombosis. report a case of PNH with characterostoc MR and CT findings. The signal intensity of renal cortex was lower than that of medulla on both T1- and T2- weighted MR imaging. On T2 weighted MR images, the liver showed very low signal intensity but the signal intensity of the spleen was normal. On precontrast CT the attenuation of renal cortex was higher than that of renal medulla and the attenuation of liver was higher than that of the spleen. These findings of MR imaging and CT were the result from the deposition of hemosiderin in the cells of proximal convoluted tubules and transfusional hemosiderosis of liver.

PURPOSE: The aim of study was to review the results of open surgical repair (OSR) of chronic juxtarenal aortic occlusion (JRAO). MATERIALS AND METHODS: We retrospectively reviewed the results of OSR performed in 47 patients (male, 92%; mean age, 59.9+/-9.3 years [range, 44-79]) with chronic JRAO during the past 21 years. In order to reduce intraoperative renal ischemic time (RIT), we excised a portion of the occluded segment of the infrarenal aorta without proximal aortic clamping. We then performed suprarenal aortic clamping with both renal arteries clamped, removed the proximal aortic thrombus cap, confirmed both renal artery orifices, and moved the suprarenal aortic clamp to the infrarenal aorta to allow renal perfusion and standard aortoiliac reconstruction. We investigated early (<30 days) postoperative surgical morbidity (particularly renal function), operative mortality, and longterm patient survival. We conducted risk factor analysis for postoperative renal insufficiency. RESULTS: The mean intraoperative RIT was 10.7+/-5.5 minutes (range, 3-25), including 6 patients who underwent concomitant pararenal aortic thromboendarterectomy. Postoperatively, five (11%) patients had transient renal insufficiency, one had pneumonia, and one patient had an acute myocardial infarction. However, there was no operative mortality or newly developed dialysis-dependent renal failure. Postoperative follow up was available in 36 (77%) patients for a mean period of 6.3 years (range, 1 month-17 years). Kaplan Meier calculations of patient survival at 5 and 10 years after surgery were 91.2% and 83.6%, respectively. CONCLUSION: We have experienced short RIT, acceptable early postoperative results and long-term survival after OSR of chronic JRAO.
