It is diffidult to distinguish benign from malignant, ulmonary nodule by conventional roentgenologic examination. But CT makes it easier to evaluate adjacent parenchymal invasion, pleural or mediastinal extension, or early metastasis to intra- or extrathoracic lymph node as well s distant organs, although only a solitary peripheral pulmonary nodule is seen on plain radiograph. Authors reviewed CT of 22 cases of histopathologically confirmed primary lung cancer seen as a solitary peripheral pulmonary mass from May 1980 to September 1984 at Dongsan Medical Center, Keimyung University. The results are as follows: 1. The incedence was most common in the 6th decade(36%). Male to female ratio was 10:1 and 2 females all had bronchioloalveolar cell carcinoma. 2. The distributions of histologic cell type were as follows: squamous cell carcinoma 40%, adenocarcinoma, small cell carcinoma, bronchioloalveolar cell carcinoma and unclassified carcinoma 14% in each cases, and adenoid cystic c rcinoma 4%. 3. The computed tomographic findings were as follows: a) Superior and posterior basal segments of both lower lobes were most frequently involved(68%). b) The mean diameter of the mass was 48mm, and most common in the range of 30-49mm in the greatest dimension(46%). c) The mean CT attenuation value was 57 H.U., and most common in the group of 41-70 H.U.(64%). d) Lymph node metastasis was found in 13(59%) of 22 cases, and the involved nodes were as follows: hilar nodes 10 cases, paratracheal nodes 8 cases, subcarinal nodes 7 cases and extrathoracic nodes 3 cases. In 2 of 3 cases with small cell carcinoma, diffuse multiple lymph nodes were involved. e) Distant metastasis was seen relatively early in 3 cases: cerebral metastasis in 1 case of squamous cell carcinoma, right adrenal metastasis without intrathoracic lymph node metastasis or invasion of adjacent structures in 1 case of bronchioloalveolar cell carcinoma, and liver and bone metastases in 1 case of unclassified carci oma. f) Adjacent pleural or mediastinal invasion was found in 7 cases(32%): pleural invasion alsong chest wall in 4 cases, and invasion of adjacent mediastinal pleura in 3 caes of 2 squmous cell carcinoma and 1 unclassified carcinoma. g) Calcifications within the mass were found in 5 caes(23%), and most common in squamous cell carcinoma(3 caes). In all cases, a few granular calcifications were seen along the peripheral margin of the mass. h) Tumor necrosis was seen in 4 cases(18%), and 3 cases were squamous cell carcinoma, and one of them showed irregular central cavitation. i) The margins of tumor were irregularly lobulated with radiating spiculations in all except one of adenoid cystic carcinoma, which revealed oval shaped, smooth clear margin. j) In 9(41%) of 22 cases, some enlargement of pulmonary vessels with perivascular linear infiltrations were found in the adjacent lung parenchymes of the mass, which were thought to be retrograde perivascular lymphangitic spread along pulmon ry vessels.

The localized intraabdominal bile collection or biloma has recently been diagnosed in increased frequency due to the wide spread use of US, CT, DISIDA scintigram, and radiologically guided percutaneous needle aspiration with or without subsequent catheter drainage. The underlying cause of biloma is trauma or iatrogenic injury which includes abdominal surgery, percutaneous drainage or PTC. We experienced 20 patients with 22 biloma diagnostically confirmed by DISIDA scan, image-guided needle aspiration, percutaneous catheter drainage and/or operation. Of the 22 biloma, 7 were intrahepatic and 15 were extrahepatic, Of the 15 extrahepatic biloma, 7 were in partially hepatectomized bed, 3 were subhepatic, 3 were right subphrenic and 1 was subcapsular. We were able to determine the infectivity in 16 biloma and of these 12 biloma were found to be infected. Percutaneous drainage was performed on 20 biloma in 18 patients : by a needle aspiration with irrigation on 2 patient and by perc taneous catheter drainage on 18bilomas. Overall success rate of the drainage was 90%. Cause of the two failures were CHD stone with choledochoduodenal fistula and recurrent hemobilia with acute cholecystitis. We describe the processes in reaching the diagnosis of biloma, propensity of biloma to purulent intrahepatic or perihepatic abscess formation, and the necessity of percutaneous radiologic catheter drainage as an optimal management.

CT is useful for the elderly patient in whom the diagnosis of periappendiceal abscess has not been suspected clinically due to an atypical clinical presentation. CT findings and its clinical applicability of periappendiceal abscesses were reviewed retros-pectively in 11 patients older than 40 years. The correct diagnosis was possible clinically in 4 patients(36%) The CT findings were mainly cystic (45%) of mixed (36%) masses which were located inferomedially to cecum(55%) or medially to right-sided colon (27%) The common associ-ated findings were adjacent peritoneal and intestinal thickenings mesenteric and/or omental ated findings were adjacent peritoneal and intestinal thickenings. mesenteric and/or omental infiltrations in most of the cases and retroperitoneal extensin of the inflammatory process(55%) . However there we five false-positive diagnoses in patients with a fluid-filled cecum a noncomplicated acue appendicitis and three chronic inflammatory diseases of the pericecal area. CT has the potential advantage of directly imaging the periappendiceal inflammation with a full assessment of the nature localization and extension of the abscesses and may guide percutaneous drainage of abscesses as an alternative to surgical drainage.

Pseudomyxoma peritonei is characterized by mucinous ascites and implants throughout the abdominal cavity. The disseminated intraabdominal neoplasm has been associated with both benign and malignant mucus secreting tumors in men and women. There are several reports on the CT and sonographic features of pseudomyxoma peritonei, suggesting the correct diagnosis preoperatively. Authors reviewed the CT and Us findings of 10 cases of seven patients of pseudomyxoma peritonei, and the results were as follows: All cases are females and the age distribution shows from 48 to 75 years old. The common clinical symptom is markedly distended abdomen. The primary tumors of seven patients are mucinous cystadenoma 5, mucinous cystadenocarcioma 3 in ovaries, and mucocele 3, mucinous adenocarcinoma 1 in appendices and 4 cases arise from both the ovaries and the appendices. The CT findings of pseudomyxoma peritonei(n=9) are a. extensive ascites(9/9), with septation 2 cases b. scalloping of the liver margin (5/9) c. scalloping or indentation of bowel loops (8/9) d. intraabdominal cystic mass (5/9) e. peritoneal nodules (6/9) f. omental mass (5/9) g. posterior fixation of bowel loops (4/9) h. visceral invaeion (1/9) The US findings of pseucomyxoma peritonei(n=4) are a. septated, dirty ascities (3/4) b. peritoneal nodules (2/4) c. omental mass with tiny cyst (2/4) d. echogenic intraabdominal mass with numerous tiny cysts (1/4) In all cases, US and CT features were able to suggest the correct preoperative diagnosis.

Purpose: To evaluate retrospectively whether it is possible to predict the transarterial chemoembolization(TACE) result with the pre-TACE dynamic CT findings. Materials and Methods: The dynamic CT findings of 33 patients with 35 nodular and 8 massive hepatocellular carcinoma(HCCs) who was taken follow up CT after TACE, were reviewed retrospectively. After excluding the diffuse or infiltrative HCCs, the mass was classified into two groups of nodular and massive types. The size, location, degree of enhancement, pseudocapsule, portal vein(PV) thrombosis and arterioportal(AP) shunt were evaluated on the dynamic CT scans. The vascularity, multiple or parasitic blood supply, AP shunt and the possibility of superselection were considered on the angiography. After TACE, the pattern of lipiodol uptake and residual enhancing nodules were evaluated on the follow-up CT scans. Results: The good TACE results could be obtained in 18 of 35 nodular HCCs with dynamic CT findings of small size(mean=2.94cm), peripheral location, hyper-or iso-enhancement, and absence fo PV thrombosis, with angiographic finding of possible superselection, but the pseudocapsule did not give important effect on the result. Most of the massive HCCs had poor TACE results. Conclusion: The prediction of the TACE results of nodular and massive HCCs was possible with dynamic CT findings. If the good prognostic factors were not observed on the pre-TACE dynamic CT, the multiple TACE and/or combination therapy with percutaneous ethanol injection(PEI), surgical resection or others should be considered for the effective control of the HCCs.
