PURPOSE: To evaluate further the right minor and major fissure on thin-section narrow-interval CT scans with particular emphases on orientation, degree of completeness. MATERIALS AND METHODS: Thin section CT scans from 10 mm distal to carina to the proximal basal segmental bronchus were obtained at 5 mm invervals in 50 consectutive subjects. Orientation, degree of completeness, and the relationship of the minor and major fissure on thin-section CTscans were analyzed. RESULTS: Four principal types of the minor fissure could be identified according to the highest point of the upper surface of the middle lobe. At bronchus intermedius level, the major fissure appeared with its medial end anterior to lateral end in 45 subjects. The minor fissure was complete in only 10 subjects (20%). Completely absent minor fissure was noted in four subjects (8%). The major fissure was incomplete in 17 subjects (34%) at bronchus intermedius level. the minor and major fissure intersected each other in only 27 subjects (54%). The hig best point of intersection was variable. CONCLUSION: There are much more variations in the fissural complex in our study than in previous reports and these variations can be visualized well on thin-section CTscans.

The CT findings were reviewed in two patients with injuries to the gallbladder following blunt trauma. In one patient high attenuation of intraluminal blood clot within the gallbladder and associated hemoperitoneum were identified. Another patient was represented hemoperitoneum and bile leakage into the peritoneal cavity due to laceration of the fundus of the gallbladder which appeared contrasted.

Radiofrequency ablation has been frequently performed on intra-hepatic solid tumor, namaly, hepatocellular carcinoma, metastatic tumor and cholangiocarcinoma, for take the cure. But, the reports of radiofrequency ablation for intrahepatic simple cysts are few. In vitro experiment of animal and in vivo treatment for intrahepatic cysts of human had been reported in rare cases. We report 4 cases of radiofrequency ablation for symptomatic intrahepatic cysts.

The UGI studies had been performed to 238 patients below the age of 15 years during the period from Jan. 1979to Jul. 1983 in SCH hospital. The results are as follows; 1. Among 238 cases, 48 cases revealed peptic ulcers ofstomach or duodenum (20.2%). The ulcer was in 31/37 cases of male patients(22.6%), and in 17/101 cases of female(16.8). Below the age of 5 years, ulcer was noted in 9 cases among 61 cases (14.8%), whereas above 5 years, in 39cases among 177 patients (22.0%). 2. In the age group below 5 years, mostly the objective symptoms were discovered(8/9), but above 5 years, complained of subjective symtoms (30/39). 3. The predominant site of peptic ulcer wasgastric antrum in the age group below 5 years (7/9), whereas duodenal bulb above 5 years(33/43). 4. Gastric antrumor duodenal bulb deformity was revealed in 13 cases and most of them were in the age group above 5 years. 5. Alllesion so peptic ulcers in this study were benign in nature. 6. In follow up study after 1 or 2 months, ulcer wasdecreased in size strikingly(9/11).

To present CT and clinical features of active tuberculomas, we analyzed retrospectively CT findings of 14 tuberculomas (n=14) in 13 patients which appeared as solitary pulmonary nodules on plain radiographs and evaluated the response of tuberculomas to antituberculous chemotherapy. Nine tuberculomas (64%) were ovoid in shape and 10 (72%) showed smooth margin. Twelve(86%) tuberculomas were shown as low density lesions on unenhanced or enhanced CT scans. Calcification and cavitation were noted in three (21%) and eight (57%) tuberculomas respectively. Seven (50%) tuberculomas were accompanied by satellite nodules. Acid-fast bacilli (AFB) was positive in all tuberculomas in sputum, lavage fluid, or percutaneous transhoracic needle aspiration (PTNA). Smear and culture of lavage fluid and PTNA aspirate were superior to the detection of AFB than sputum examination. Follow-up study with antituberculous chemotherapy in 14 tuberculomas resulted in complete disappearance in three, decrease in size in seven, and no visible change in the remaining four. These observations suggest that tuberculomas are well-defined, ovoid, and low-density nodules containing calcifications and/or cavitations. Tuberculomas are relatively indolent even with threatment.

PURPOSE: To evaluate the extrahepatic spread of peripheral cholangiocarcinoma with CT. MATERIALS AND METHODS: We retrospectively reviewed CT findings of extrahepatic spread in thirty-six patients with peripheral cholangiocarcinoma confirmed adenocarcinoma at surgery(n=5) or percutaneous biopsy(n--31) without primary leion in other organs, and analysed the frequency and distribution of enlarged lymph nodes, direct invasion of adjacent solid organs, and thrombosis of major vessels. RESULTS: Among the 36 cases, enlarged metastatic lymph node was noted in twenty-four(66.7%), direct invasion into adjacent organs in six(16.7%), portal and inferior vena caval thrombosis in five(13.9%). Enlarged lymph nodes were seen in hepatic nodes(n=16, 44.4%), portocaval nodes(n=15, 41.7%), interaortocaval nodes (n=10, 27.8) and celiac nodes in two(5.6%). Direct invasion was detected in the greater omentum(n=6), gallbladder(n:3) and stomach(n=2). Portal vein thrombosis(n:5) and thrombosis of inferior vena cava(n=2) were noted. CONCLUSION: Lymph node metastasis was seen in 67% in patients with peripheral cholangiocarcinoma. Direct invasion to adjacent organs and thrombosis in portal vein or inferior vena cava were occasionally associated.

Retroperitoneal duodenal rupture is rare and is often difficult to diagnose on the plain abdominal x-ray. From a review of the plain abdomen films of 21 cases with retroperitoneal duodenal rupture, confirmed by operation, pneumoretroperitoneum was revealed in 16 cases; Air in the peritoneum was manifested as a bubbly shadow in 12 cases, a renal halo in 9 cases, air shadow along the right psoas margin in 2 cases, air along the diaphragmatic crus in 2 cases and air in the right properitoneal fat in 2 cases, US and CT also revealed air bubbles and fluid collection around the right kidney. We recommend the plain abdomen as a useful diagnostic method for detection of pneumoretroperitoneum.

Bone scan using 99m Tc-MDP is the most accurate and reliable method for the early detection of fracture, andgive the most accurate in formation about the healing process of fractured bone. Recent days, the medicolegalproblem about the injured time is frequently provoked in vertebral fracture patient by trauma. The authorsanalyzed the bone scan of vertebral fracture patients from March to Dec. 1983. The authors obtained results asfollows: 1. The minimum time for a fracture to return to normal on a bone scan was 4 month in cervical spine. 2.It was 12 month in thoracic spine. 3. It was 6 month in lumbar spine. 4. Surrounding soft tissue injury was healedwithin 10 days after trauma in our cases. 5. Focal hot uptake is persisted in case of callus deposition on plainfilm, although very small in amount. 6. Healing time is delayed in case of severely compressed vertebral body,belowed the half than normal height. 7. With bone scan it is possible to differentiate the fresh fracture from oldhealed, impossible by plain film. 8. Healing time is delayed in old age.

Gastritis cystica polyposa(GCP) is a polypoid cystic lesion showing all the histological features of the hyperplastic polyps and the cysts penetrating through the mucularis mucosae. Most reported GCP lesions were developed at gastraenterostomy stomas. It is rare that GCP develops without history of previous gastroenterostomy. In 1990, however, Kim et al reported a GCP presenting as a submucosal tume-like lesion in a 69-year-old man. Recently, we had experienced two consecutive cases of GCP diagnosed by endoscopic polypectomy. The first case was 49-year-old housewife without history of previous gastric surgery. Esophagogastroduodenoscopy(EGD) showed a 2.0x1.5x1.5cm sized lobulated polypoid lesion with a broad stalk on the anterior wall of the distal antrum. The second case was 45-year-old woman without history of previous gastric surgery. EGD revealed a 1.0 x 1.0 x l.0 cm sized polypoid lesion with a pedicle on the greater curvature aspect of the upper body and two duodenal ulcers with pseudodiverticulum formation. These lesions were endoscopically polypectomized and diagnosed as GCP by the histologic examination.
