Imperforated hymen, vaginal atresia or high transverse vaginal septum are caused by incomplete vaginal canalization. The infant may be present with distention of the vagina and the uterus with glandular secretions stimulated by maternal estrogens, known as hydrometrocolpos. We report two cases of hydrometrocolpos. In the first case, distal vaginal atresia with cystovaginal fistula was revealed by a contrast fluoroscope through the percutaneous catheterization. In the second case, urogenital sinus was detected by a fistulogram through a single orifice in the genital area. We decompressed the cystic mass by ultrasonogram guided aspiration, promptly at birth, then achieved the transient drainage of cystic fluids by percutaneous catheterization.

In a 43-year-old Korean man who underwent radical gastrectomy due to a malignant stromal tumor, was found to have an enlarged Iymph node at transverse mesocolon. The Iymph node exhibited histologically necrotizing eosinophilic granuloma formed around a track containing sections of a nematode larva. The well preserved nematode sections revealed polymyarian muscle cells, Y-shaped lateral cord, a large excretory gland cell, intestine and eosinophilic cuticle. The nematode sections were identified as a larva of Anisnkis species In Korea, thIns is the first case of elrtragas trio into stinal anisakiasis.

Abdominal tumors that can grow through vascular lumen and spread to the right heart are rare. Intravenous leiomyomatosis is a rare tumor that originates from the uterus and spreads through the vessels. Although histologically benign, tumor extension with mechanical obstruction of the inferior vena cava, right cardiac cavities, or even the pulmonary artery, may occasionally result in fatal outcome. The best treatment is complete surgical resection of the entire tumor using cardiopulmonary bypass and total circulation arrest, We report a case of intravenous leiomyomatosis of the uterus that showed intravascular growth up to the right atrium. The patient underwent successful resection of the tumor by one-stage cardiotomy with laparotomy.

Inflammatory pseudotumors (IPTs) are uncommon, mass-forming lesions, predominantly involving the lung and orbit. Although the incidence of IPTs is rare in the abdomen and pelvis, they can be encountered as enhancing, soft-tissue lesions, mimicking malignancy or fibrosclerosing disease. Generally, they exhibit a wide range of nonspecific imaging features in various organs. Preoperative imaging diagnosis of IPTs in appropriate clinical settings may help determine proper patient management. In this article, we review radiologic findings of IPTs in the abdominopelvic cavity, including the liver, spleen, kidney, gastrointestinal tract, mesentery, pelvis, and retroperitoneum.

We report the case of a girl with peritoneal tuberculosis (Tb) who presented with mimicking features of ovarian cancer including massive ascites, elevation of CA-125 and ovarian masses. These ovarian masses cannot be ruled out malingnacy with image study. Gram stain, acid-fast stain, bacteriological and mycological culture of centrifuged ascites cells were negative. Tumor markers revealed an elevated CA-125 level of 112 U/mL and adenosine deaminase level were significantly high with 118 U/L. Diagnostic laparoscopy was done. The histology of the peritoneum and the ovary showed multiple granulomatous nodules with epithelioid cells and multi-nucleated giant cells. And there were no evidence of malignancy. Furthermore acid-fast bacilli (AFB) was identified in this specimen. Peritoneal Tb was difficult to diagnosis in our patient because it mimicked ovarian cancer. And this is the first case of abdominal Tb mimicking ovarian cancer in children in Korea.

A 13-year old, female Maltese dog was presented due to a five-month history of episodic syncope. A diagnosis of sick sinus syndrome (SSS) with mitral valve endocardiosis (MVE) was made based on history takings, physical and cardiac examination, complete blood count (CBC), serum chemistry profiles, radiography, electrocardiography (ECG), atropine response test, hormonal assay, and echocardiography. In this case, SSS was definitely diagnosed by evaluation of ECG recording following atropine administration. Clinical signs were improved with medical management of theophylline (THEOLAN, KunWha Pharm, Seoul, Korea, 20 mg/kg, PO, BID). After 10 more month survival, the dog, died of respiratory distress and shock during the operation of abdominal mass removal in local animal hospital. Unfortunately, we were not able to perform necropsy after death due to owner's decline. This case demonstrates that theophylline can be used in management oF dog with SSS.

Purpose : Renal cystic diseases comprise a mixed group of heritable, developmental and acquired disorders. Recently the use of imaging modalities such as ultrasonography and radionuclide scanning has increased the detection rate of renal cystic diseases. We studied to review the clinical features and treatment of renal cystic diseases in children. Methods : This study was performed in 95 children with renal cystic diseases in the Department of Pediatrics, Asan Medical Center from October 1989 to June 2001. Results : In 95 patients, there were 55 cases(58.0%) with multicystic dysplastic kidney(MCDK), 19 cases(20.0%) with simple renal cysts, 13 cases(13.7%) with hereditary polycystic kidney diseases( 7 with autosomal recessive type, 5 with autosomal dominant type, 1 with undetermined), 6 cases(6.3%) with renal cysts in tuberous sclerosis and 1 case(1.0%) with medullary cystic disease. All MCDK patients had no renal dysfunction and hypertension during the follow-up period. Three out of 13 with polycystic kidney diseases had progressed to end-stage renal disease during the follow-up period. One case with a simple cyst underwent laparoscopic malsupialization for decompression. Conclusion : Renal cystic diseases have diverse clinicopathologic features and variable prognosis. We emphasize that routine follow-up should be performed to prevent and to detect early treatable complication in renal cystic diseases. Therefore, their natural history and treatment need further investigation and long term follow-up is required.
