Thrity one lymph njodes in thirty follow-up CT studies in 9 patients with a diagnosis of malignant lymphoma were reviewed to determine the efficacy of CT studies for determining response of the therapy. In these 9 patients, CT findings are subdivided to 5 groups by the gross appearances of lymph nodes; (a)complete disappear, (b)multiple strands, (c)decreasd size without changes in internal characteristics, (d)decreased size with central low density, (e)increased size. Clinical correlation preceding the follow-up CT examination was obtained and it's correlation was very excellent. The group (a) to (d)were matched with good clinical course and group (e)was matched with poor clinical course. The appearances of the lymph nodes were not correlated with the histologic cell types and methods of therapy. The CT examination is satisfactory in the post-therapy follow-up of lymphoma patients.

The Chiari IV malformation is a very rare condition which is characterized by severe cerebellar hypoplasia or aplasia. Morphologic findings include aplastic or severely hypoplastic cerebellum, small brainstem and relatively large cerebrospinal fluid space in the posterior cranial fossa. We recently experienced Chiari IV malformation and report radiologic findings of the case.

Purpose: We evaluate the pathway of the stalk of antrochoanal polyp on the coronal and axial computed tomography scans (CT), comparing with operative findings. Materials and Methods: Fourteen patients (7∼40 years old, median= 12.5 years old, ratio of male to female: 8/6) with antrochoanal polyp were examined, who took the orbitomeatal unit (OMU) CT including both coronal and axial scans as well as the operation. The CT findings and clinical findings were analyzed for the pathway of the stalk of antrochoanal polyp, comparing with the operative findings. Results: The antrochoanal polyps were mostly located on the left side (12/14, 85.7%) and equally passed through the natural and accessory ostia (7/14, 7/14) in our cases. Those that were passing through the accessory ostium were located more inferiorly and posteriorly, with preserving the natural ostium on CT scans, comparing to those via the natural ostium. However, those passing through the natural ostium had a larger stalk that eroded the uncinate process widely. So each ostium was hardly discriminated on CT scans. Conclusions: The pathway of the stalk of the antrochoanal polyp could be more specifically evaluated on both coronal and axial OMU CT scans. So, it could be more hilpful in the presurgical planning.

Small cell carcinoma(also known as oat cell carcinoma) of the urinary bladder is an extremely rare malignancy and is derived from neuroendocrine stem cells. It is usually biologically aggressive tumor with early vascular and muscle invasion, so it has poor prognosis. Radiological findings of small cell carcinoma are similar to other malignancies of urinary bladder, therefore it is impossible to distinguish small cell carcinoma from other malignancies. Pathologic study is an only useful method for differential diagnosis of bladder tumor. We report here the case of 74th years old woman presented with painless gross hematuria.

We have experienced a case of presacral ganglioneuroma. So, we report a peripheral ganglioneuroma of sacral origin. The patient is 34-year-old man with intermittent low back pain and right sciatica. Myelographic computed tomography revealed extradural lobulated low attenuated tumor lesion within spinal canal at the level of L5 and S1. Tumor indented the thecal sac to the left side, and extended into the pelvic cavity through the intervertebral foramen between S1 and S2. The mass was surgically excised and turned out to be ganglioneuroma pathologically.

Purpose : To determine the incidence of identifying organism from the diffusely calcified thoracic mass which is ususlly caused by tuberculosis in Korea and has been considered needless to be followed up and, if organisms are identified, to decide whether those patients should be medicated or not. Materials and methods : From consecutive patients who had undergone percutaneous needle aspiration(PNA) of thoracic lesion, we selected patients who met the following criteria : (a) visible calcification in more than half of the lesion volume on CT(b) negative acid-fast bacilli (AFB) in sputum. These included 6 patients with pulomonary nodules and one with a paratracheal lymph node. AFB staining was done of PNA specimen and follow-up radiographs of patients with positive AFB lesion were reviewed after antituberculous chemotherapy. Result : AFB was demonstrated in six(85.7%) and only caseation necrosis in the other one. Antituberculous medication was done in all Among five patients whose radiographs were available during the follow-up period of 1-17 months after medication, only one showed silight decrease in size. Conclusion : Although the effect of antituberculous chemotherapy is doubtful, careful follow-up is needed even to the tuberculous lesion with diffuse calcification because orgainisms are present in those lesions.

We evaluated CT findings of the small cell carninoma, which presented as a solitary pulmonary nodule at the periphery of the lung parenchyma. Of pathologically-proven 45 patients with small cell carcinoma, 10 patients was included in this study, who had a solitary, peripheral lung nodule at distal portion of the subsegmental bronchus. We retrospectively reviewed clinical data and CT findings including size, location, margin, enhancement pattern, lymph node enlargement, metastasis. Peripheral small cell carcinomas were 22.2%(10/45). All masses had well-defined margin and lobulated margin was seen in 7 patients. Mean diameter was 3.8cm (2.5-7.0cm). Enhancement pattern were homogeneous in 3 cases and inhomogeneous in seven. Calcification or air-bronchogram was not present, and focal cavitation was seen in one case. In five, only lung mass was present, and lung mass with lymph node enlargement was seen in one. distant metastasis without lymph node enlargement was noted on two patients and another two patients showed lymph node enlargement and distant metastasis. Peripheral small cell carcinoma is not rare(22.2%). Most frequent CT finding is a well-defined, lobulated mass with inhomogeneous enhancement, these findings would be helpful in differentiating small cell carcinoma from other neuroendocrine tumors when differentiataion is difficult cytologically.

For the study of correlation of ct number and fatty content of the liver, total 35 rabbits were used. The rabbits were divided into one control and three experimental groups according to the amount of carbon tetrachloride, administered 1 ml, 2 ml and 3 ml per kg of body weight respectively. The carbon tetrachloride was administered via intragastric route. CT was performed 72 hours following administration of carbon tetrachloride, and immediately prior to CT scan each rabbit was anesthetized by means of IM injection of ketamine and IV injection of succinylcholine to stop motion and respiration. CT numbers were measurd and histological study for the deposition of fat in the liver tissue was done. Also biochemical analysis of lipid in the blood and in the extraction of liver tissue was performed. Comparison of CT number with biochemical and histological data was done. The results were as follows: 1. In each experimental group, the degree of accumulation of fat in the liver was proportional to the amount of carbon tetrachloride. 2. Degree of decreasing CT number was correlated with the increase in the accumulation of fat in the liver. 3. In the control and experimental (1,2,3) groups, when the amount of carbon tetrachloride increased, the amount of total lipid, cholesterol and triglyceride on biochemical analysis of the liver increased. Also increase in the amount of plasma lipids on biochemical analysis and a great degree of increase in accumulation of fat in the liver on histological examination were seen. But no changes in the amounts of phospholipid and protein on biochemical analysis of the liver were noticed. 4. Increase in the amount of total lipid could make a change in the CT number of the liver remakably (r=-0.63). As the amount of cholesterol and triglyceride increased, the CT number of the liver decreased (r=-0.61 and r=-0-.76 respectively). But there was no significant correlation between the amount of protein and phospholipid and the degree of decrease in CT number. 5. Mean values of CT number in normal, grade 1, grade 2, grade 3 and grade 4 according to the degree of histological changes were 67.46±2.24, 58.53±3.06, 49.43±6.81, 39.49±9.69, 20.62±8.04 respectively. The reduction of CT number was correlated with the accumulation of fat on histological examination.
