Two cases of urachal anomaly (1 urachal cyst and 1 patent urachus) are reported in a neonate and an eleven-year old boy, respectively. In case 1, the patient was born after an uncomplicated pregnancy to a mother who had taken progesterone during the first trimester. Because of breech presentation, cesarian section was elected to deliver a male baby weighing 2.3 kg who showed abdominal distension. The patient died of respiratory difficulty several minutes after birth. At autopsy, there was a large cyst in the midpoint of the abdominal and pelvic cavity. This round cyst was composed of two components, urachus and urinary bladder. No area of umbilicocystic fistula was present. The lining epithelium was chiefly of transitional type. Assocaited anomalies were segmental stenosis of posterior urethra, absence of abdominal musculature, bilateral polycystic kidney of Potter type IV, hydroureter, and hypoplasia of lungs. Low set ears, micrognathia and club foot were also present. In case 2 the patient was 11-year old boy. He had suffered from intermittent urinary dribbling from umbilicus since early infancy, whenever the abdominal pressure was increased. The patency of urachus was confirmed by fistulography. And the urachal anomaly was surgically removed. Histopathologically the resected patent urachus consisted of pseudostratified columnar to transitional epithelium resting on fibrous stroma mixed with well formed smooth muscle bundles.

Encapsulated papillary carcinoma (EPC) is an uncommon breast malignancy that is known to be indolent and associated with an excellent prognosis. However, there is a rare possibility of locoregional relapse or metastasis. Here, we present a case of recurrent EPC in the ipsilateral internal mammary lymph node (IMLN) that was detected in the postoperative magnetic resonance imaging with abbreviated protocol (AB-MRI). AB-MRI could facilitate the early detection of recurrent disease in the IMLN and may provide prognostic gain for such patients.

The aim of this case report is to draw the attention to the occurrence of cystic fibrosis (C.F.) in a Korean infant and thus increase the awareness for the diagnosis. The male infant was presented with a history of recurrent bronchiolitis manifested by severe cough, wheeze and dyspnea from three weeks of age, in whom the diagnosis of C.F. was clinically suspected and was confirmed by demonstration of two elevated sweat chloride levels (97 mEq/L and 99 mEq/L) in the patient. The diagnosis was delayed because the main manifestations of C.F. were the same as the main symptoms of common diseases such as cough, diarrhea and failure to thrive. C.F. is probably underdiagnosed in Korean population both because the diagnosis is not considered since the disease is thought to be uncommon or even not to occur and because diagnostic facilities including the quantitative iontophoresis sweat test are lacking.

PURPOSE: To evaluate the changes and normal ranges of the artery-bronchus ratio (ABR) during respiration MATERIALS AND METHODS: We analyzed HRCT of 10 healthy adults. The HRCT findings of ten healthy adults were analysed. CT scanning was performed with 1 mm collimation at 3 mm intervals during full inspiration and full expiration, with a range during inspiration from 2 cm to 4 cm above the carina and from 4 cm above to 2 cm below the right hemidiaphragm. The range during expiration was from 1 cm to 3 cm above the carina and from 4 cm above to 2 cm below the right hemidiaphragm. ABiR (defined as the diameter of pulmonary artery divided by the inner diameter of the bronchus), ABoR (defined as the diameter of pulmonary artery divided by the outer diameter of the bronchus) and BLR (defined as the inner diameter of the bronchus divided by the outer diameter of the bronchus) were measured on the display console. RESULTS: The mean inner diameter of the bronchi was 2.04+/-0.73 mm during inspiration and 1.68+/-0.51 mm during expiration, while the mean diameter of the arteries was 3.95+/-1.03 mm during inspiration and 4.37+/-1.09 mm during expiration. The diameters of the bronchi were thus seen to increase during inspiration, and the diameters of the pulmonary arteries, to decrease. The mean thickness of the bronchial wall was 1.07+/-0.19 mm during inspiration and 1.06+/-0.24mm during expiration; thus, no change in thickness was seen during respiration (p<0.05). Mean ABiR was 2.01+/-0.60 (range 1.15-4.58) during inspiration and 2.59+/-0.74(range 1.16-4.9) during expiration, and in all cases the inner diameter of the bronchus was less than that of the accompanying pulmonary artery. Mean ABoR was 0.91+/-0.19 during inspiration and 1.09+/-0.22 during expiration. while for BLR, the corresponding fingures were 0.46+/-0.06, and 0.44+/-0.09. CONCLUSION: HRCT is a useful tool for evaluating changes in the pulmonary arteries and bronchi during respiration.

Systemic infections of campylobacter fetus are rare in human beings. Only 22 cases(including our case) of C. fetus infection have been reported in Korea. We are presenting a case of subdural empyema caused by C. fetus. The patient was a 71 year old man of chronic alcoholism.

PURPOSE: To evaluate the effect of respiration on the sizes of intrathoracic vasculature, and the trachea,and the main bronchus. MATERIALS AND METHODS: Seventeen volunteers (10males aged 20-39 years and 7 females aged20-39 years) underwent spiral CT, between the apex and lowest base of the lung, collimation was 10mm, pitch was 1,and images were obtained at breath hold forced end-inspiration and breath hold forced end-expiration. Crosssecional areas or diameters were measured in each respiration state at the aorta (ascending, descending, lowerthoracic) and great branches, the IVC (thoracic, abdominal), the SVC, pulmonary artery (right main, leftdescending) and the tracheobronchus (trachea, left upper bronchus). Changes in the size of vessels and airwaysbetween the respiration states were evaluated and compared between inspiration and expiration. RESULT: Duringbreath-hold forced end-inspiration CT, the ascending, descending, and lower thoracic aorta and itsbranches(brachiocephalic, left common carotid, left subclavian) as well as the thoracic IVC and SVC and the rightmain and left descending pulmonary arteries decreased in size: during breath-hold forced end-expiration CT, thesize of all these vessels increased. For the trachea, left upper lobe bronchus and abdominal IVC, the situationwas reversed. Statistically significant changes(p<0.05) were noted in the ascending aorta and descending aorta,the lower thoracic aorta, the thoracic and abdominal IVC, the SVC, the right main and left pulmonary arteries, andthe trachea. CONCLUSION: During respiration, changes in the size of the thoracic vasculature and airways isprobably due to changes in intrathoracic pressure. In the measurement and diagnosis of stenosis or dilatation inthe intrathoracic vesculature and airways, respiration states should therefore be considered.

A human case of intestinal metagonimiasis that was incidentally found during the histological examination of a resected segment of jejunum was described. The small adults trematode of Metagonimus yokogawai were found free in jejunal lumen as well as impacted in intervillous spaces. Histologically intestinal lesions were massive lymphoplasmacytic and eosinophilic infiltration in stroma, erosion of neanby enterocytes, goblet cell depletion and occasional villous edema. Scanning electron microscopy revealed the worm of spatulate appearance with rake-shaped tegumental spines. By transmission electron microscopy, the syncytial integument with dense discoidal bodies, basement membrane muscle cells and subtegumental cells were observed. Characteristic junctional complex was demonstrated between subtegumental and parenchymal cells as well as between parenchymal cells.

There have been an increasing number of reports of intraductal papillary mucinous neoplasms (IPMNs) of the pancreas since its first report by Ohhasi et al. in 1982. Most IPMNs arise from Wirsung's duct or its branches, whereas IPMNs arising from Santorini's duct are rare. Pancreas divisum is a common congenital anatomical anomaly characterized by the lack of fusion of the ventral and dorsal parts of the pancreas during the eighth week of fetal development. Although clinical significance of pancreas divisum has been the subject of debate for many years, there seems to be little doubt that in certain patients there is a causal relation between pancreas divisum and pancreatitis. Also, it is occasionally accompanied by a pancreatic tumor. Herein, we report a case of IPMN arising from Santorini's duct in patient with complete type of pancreas divisum.
