PURPOSE: To describe CT findings and differential points of cystic thymic lesions. MATERIAL AND METHOD: We evaluated retrospectively total 19 masses with well marginated cystic lesions at thymic area on CT scans. They were 10 teratomas, 3 congenital thymic cysts, 2 multilocular thymic cysts(associated with thymoma and myasthenia gravis in each), 2 cysts Assciated with thymic Hodgkin's lymphomas an ectopic parathyroid cyst, and an infected thymic cyst. The radiological abnormalities evaluated were thickness of the wall, presence or abscene of septa, mural nodule, solid component, calcification and fat component. RESULTS: All three cases of congenital thymic cysts and an ectopic parathyroid cyst appeared as thin-walled unilocular cyst with homogeneous internal density and without identifiable solid component. In multilocular thymic cyst, there were thick wall and solid components(n=2), thick internal septa and calcifications(n=l). The cysts of teratomas manifested thick walls(n=9), internal septa(n=4), calcifications(n=6), fat components(n=4), and solid components(n=4). Cysts in Hodgkin's diseases appeared as multilocular or unilocular and had thick wall and septa without calcification. infected thymic cyst presented with multilocular cystic mass with identifiable wall and septa, calcification, and solid components. CONCLUSION: The thymic diseases with cystic lesion include teratomas, congenital thymic cysts, multilocular thymic cysts, parathyroid cyst, .and Hodgkin's disease. Congenital thymic cyst and ectopic parathyroid cyst are thin-walled unilocular cystic lesions. Cystic lesions associated with teratoma, Hodgkin's disease, and multilocular thymic cyst are thick-walled cystic lesions with or without solid component.

A 21-year-old woman presented with productive cough and hemoptysis. Chest radiograph shows a large thin-walled cystic lesion with an air-fluid level in medial portion of the left lower lung zone and opacity in paravertebral area of the right lower lung zone. Chest CT scan shows a thin-walled cavitary lesion in the posterior basal segment of left lower lobe with an air-fluid level. Area of consolidation containing air-filled cysts was also observed in medial aspect of right lower lobe. Selective angiogram obtained from aberrant artery arising from descending abdominal aorta showed two main branches of the artery supplying bilateral pulmonary lesions.

The duodenum is the second most common site of diverticula following the colon, but is associated with fewer complications than colonic diverticula. Diverticulitis, cholangitis, pancreatitis, perforation, hemorrhage, and blind loop syndrome may occur as complications of duodenal diverticula. Although nonoperative treatment is an option for patients in good condition without signs of sepsis, surgery is generally required for definitive treatment of complications. There are several surgical procedures for symptomatic duodenal diverticula. We performed laparoscopic duodenal segmental resection and duodenojejunostomy without open conversion in three cases. We believe that this procedure is ideal for cases of symptomatic duodenal diverticula when performed by an experienced surgeon with the goal of definitive treatment.

Primary carcinoma of the female urethra is relatively rare neoplasm. Urethral cancers account for less than 0.02 per cent of all neoplasms occurring In women and 0.01 per cent of all urologic malignancies. The rarity of the disease as well as the changes and improvements in the various treatment modalities have prevented unanimity of opinion with regard to its proper treatment. We report one case of transitional cell carcinoma in female urethra with brief review of the literature.

Deep vein thrombosis (DVT) is a condition that affects hundreds of thousands of patients each year and treated with anticoagulation therapy alone to stop propagation and embolization of venous thrombus but not remove it. Extensive clinical research over the last 40 years has improved the techniques to remove the thrombus from the affected veins and reduce the likelihood of developing post-thrombotic syndrome. These endovascular treatments includes catheter-directed thrombolysis and recently pharmacomechanical thrombectomy to rapidly fragment, lyse, and remove the thrombus from the affected veins resulting in short treatment time, and improved the quality of life of the patients. This article provides an overview of the interventions available for treating DVT.

Popular use of intravascular catheterization of both diagnostic and therapeutic purposes led to increase in iatrogenic intravascular foreign bodies for which percutaneous removal has been accepted as the treatment of choice. The majority of percutaneously removed intravascular foreign bodies are located in the right side of the heart, large veins, and pulmonary arteries and intraarterial foreign body is rare. We recently experienced a case of intraarterial fragmented catheter which was removed with a basket percutaneously without any complication.

Behcet's disease is a chronic inflammatory disease of an unknown etiology, and it is characterized by recurrent oral and genital ulcerations, eye lesions skin lesions, and other involvement such as gastrointestinal ulcerations and lesions of the central nervous system and major vessels. The vascular lesions include deep vein thrombosis, superficial thrombophlebitis, arterial aneurysm and arterial occlusion. Aortic aneurysm or pseudoaneurysm is a rare complication, but it is one of the most common causes of death in Behcet's disease. We report here on a case of a 43 year old female with Behcet's disease that was complicated by an abdominal aortic pseudoaneurysm, and this was all successfully treated with percutaneous endovascular stent graft insertion, steroid pulse therapy and azathioprine.

OBJECTIVE: Percutaneous vertebroplasty is often complicated by the presence of multiple fractures or non-localizing pain in the patients with osteoporotic vertebral fractures. The purpose of this study is to estimate the value of preoperative radiologic studies in the localization of symptomatic vertebrae and to determine the factors which can influence on the clinical results. MATERIALS AND METHODS: We retrospectively reviewed the clinical and radiologic data of 57 vertebrae in 30 patients underwent percutaneous vertebroplasty for osteoporotic vertebral compression fractures. Inclusion criteria was severe pain(McGill-Melzack score 3, 4 or 5) associated with the acute vertebral fractures and absence of spinal nerve root or cord compression sign. Acute symptomatic vertebral fracture was determined by the presence of signal change on MR images or increased uptake on whole body bone scan. RESULTS: Pain improvement was obtained immediately in all patients and favorable result was sustained in 26 patients(86.7%) during the mean follow-up duration of 4.7 months(5 complete pain relief, 21 marked pain relief). Those who underwent vertebroplasty for all acute symptomatic vertebrae had significantly better clinical result than those who did not. Further vertebral collapse and eventual bursting fracture occurred in 1 vertebra which showed intradiskal leakage of bone cement and disruption of cortical endplate on postoperative CT scan. CONCLUSION: Preoperative MR imaging and whole body bone scan are very useful in determining the symptomatic vertebrae, especially in the patients with multiple osteoporotic vertebral fractures. To obtain favorable clinical result, the careful radiologic evaluation as well as clinical assessment is required. Control of PMMA volume seems to be the most critical point for avoiding complications.

Postpubertal mumps may result in ochitis and permanent testicular atrophy may develop following infection. This present study was initiated to evaluate the preventive effect of interferon-alpha2B on infertilty after mumps orchitis. There were 21 patients with mumps orchitis between May 1990 and June 1997. Patients were randomly distributed into 2 groups: group 1 patients (n=13) maintained therapy with interferon-alpha2B (3x10(6) IU per day) and group 2 were managed by conservatively. All of the patients were evaluated with testis size measurement, mumps virus titer, hormone level, and if possible semen analysis. For group 1 patients symptoms disappeared within 2 to 3 days and the volume of testis returned to normal within 11 days and testis atrophy was not observed in all patients in follow up. But asthenospermia was continued in 4 patients (unilateral 2, bilateral 2). For group 2 patients symptoms disappeared within 5 to 6 days and the volume of testis returned to normal within 10 days and testis atrophy was observed in 3 patients (unilateral 2, bilateral 1) in floow up. Asthenospermia was continued in 4 patients (unilateral 2, bilateral 2). Sperm count and morphology were recovered all the recover in group 1, 4 patients had persistent reduced sperm count and morphology in group 2, respectively. These observations suggest that systemic interferon-alpha2B treatment is highly effective in preventing infertility as well as testicular atrophy after mumps orchitis.
