PURPOSE: We evaluated the frequency of detection of small hepatic cystic lesion(SHC) on abdominal CT films and its significance in patients with extrahepatic malignancies. METHODS AND MATERIALS: We retrospectively reviewed the abdominal CT films of a total 1112 patients to determine the frequency of detection of SHC, and 62 patients who had both extrahepatic malignancies and SHC were selected. A total 106 SHC determined as benign or malignant in 40 patients was analyzed according to the size(< 1 cm, 1 2cm), the number(1, 2 4, >4), the margin(well-defined, iil-defined),and the location(central, peripheral) of individual cystic lesions. The findings of follow-up CT and ultrasonography and the results of biopsy were also reviewed. The frequency of combined renal cyst was also considered. RESULT: SHC of those 62 patients were classified as benign(27 patients, 43.6%), malignant(13 patients, 20. 9%), or undetermined(22 patients, 35.5%) by the follow-up CT, ultrasonography, and biopsy. Most benign SHC (74.4%) measured under 1 cm, but 75% of the malignant SHC were in 1 -2cm in size. The percentage of the malignancy in one and two to four SHC was 37.5% and 40%, respectively. The margin of SHC was ill-defined in 67.9% of the benign and 64.3% of the malignant lesions. SHCs were mainly located at the periphery of the liver(benign :62.7%, malignant: 64.3%). Coexisting renal cyst was rare. CONCLUSION: SHC is not uncommon finding(13.2%) in patients with extrahepatic malignancy and has a high probablity of metastasis when it is larger than 1 cm, which should be closely followed and intensively studied further.

OBJECTIVES: In order to standardize the CRP, ESR and WBC count after three types of spinal surgery and get clinical usefulness from these laboratory dadas after spinal surgery and clincal usefulness of laboratory datas. MATERIAL AND METHODS: Three groups of patients(microdisectomy, anterior and posterior fusion) were chosen for the study. CRP, ESR and WBC levels were prospectively determined before surgery and at days 1-5, 10, 14,21 and 42 after surgery. RESULTS: In all patients, preoperative normal CRP level(<10mg/L) increased, reaching peak levels on the second day after anterior fusion(84.6mg/L), and at the third day after microdiscectomy(54.5mg/L) and posterolateral intercorporal fusion(152.2mg/L), with normalization in 5-10 days. Preoperative normal ESR level increased to peak level on the forth day after microdiscectomy(33.0mm/hr), and increased double peak levels after anterior(postoperative days 2&5) and posterolateral intercorporal fusion(postoperative days 3&5). ESR followed by a slow and irregular decrease, and at 42 days after surgery often remained elevated. WBC increased to variable peak level within normal limit in all patients. CONCLUSIONS: The rapid decline in CRP will probably be interrupted by a second rise or persisting elevation if infection occurs. CRP is presumably a better test than ESR for early detection of postoperative infection.

OBJECTIVE: The purpose of this retrospective study was to report the outcome of the endovascular treatment of eight patients with eight saccular posterior inferior cerebellar artery (PICA) aneurysms. MATERIALS AND METHODS: Over the last seven years (1999-2006), eight consecutive patients with saccular PICA aneurysms were treated by endovascular methods. Five of the aneurysms were presented with subarachnoid hemorrhaging, whereas three were discovered incidentally. Four of the aneurysms (3 ruptured and 1 incidental) were treated by intrasaccular coiling, whereas the remaining four (1 ruptured and 3 incidental) were treated by vertebral artery (VA) occlusion. RESULTS: Of the four aneurysms treated by intrasaccular coiling, three were completely packed with coils and one was partially packed. In three of four patients who underwent vertebral artery occlusions, follow-up digital subtraction angiographies demonstrated thrombosed aneurysms and PICA. No procedure-related morbidity occurred and no re-bleed was encountered during a follow-up examination (mean; 31 months). CONCLUSION: As a result of this study, we found that the endovascular management of saccular PICA aneurysms should be considered as safe and effective.

PURPOSE: The staging of bladder carcinoma is a major determinant of operative management. CT of bladder carcinoma has been widely used to diagnose external extension (pT3b and over), but tumors confined to the bladder wall (from pT1 to pT3a) are poorly delineated. The authors describe CT findings of the superficial bladder carcinoma (below T1, stage A) in thin section CT with air insufflation technique (air insufflation-CT) to facilitate early detection and to aid correct staging of the superficial bladder carcinoma. MATERIALS AND METHODS: The materials consisted of proved 24 cases (1'9 patients, single tumor: 16 patients, multiple tumors :3 patients) of stage A bladder carcinomas. Air insufflation-CT was performed by the infusion of approximately 200 mL of air into the bladder via a Foley catheter. After the routine pelvic CT, bladder tumors were re-scanned with 1.5 to 5 mm thickness and intervals. RESULTS: The superficial bladder carcinomas were detected as nodular(5 cases, 20.8%), papillary(15 cases, 62.5%), pyramidal(2 cases, 8.3%), and domed(2 cases, 8.3%) forms on air insufflation CT. These tumors were classified into three types according to the size of the tumoral neck:type I(pedundulated polypold tumor:4 cases, 16.6%), type II(polypid tumor with short neck :13 cases, 54.2%), and type Ill(sessile tumor :7 cases, 29. 2%). The mean size(tumoral width x height x base o, neck/stalk) of the tumors was 22 x 20 x 16mm. The average tumoral sizes according to each type of the superficial tumors were type 1:22 x 25 x 6mm, type 11:23 x 22 x 18mm, and type III :18 x 15 x 18mm. The mean width of the type I--II tumoral necks was 15mm. The mean length of the type I tumoral neck(pedicle) was 2.5mm. Papillary fronds of the tumors were seen in 10 cases(41.7%) of 24 superficial tumors. Outer margin of the involved bladder wall was smooth in all cases. CONCLUSION: Thin-sectin CT with air insufflation technique for bladder carcinoma was useful in tumoral demonstration, and characteristics of the superficial bladder carcinomas were small polypold tumors had a short neck mostly and smooth outer wall of the involved bladder wall.

Diffuse large B cell lymphoma (DLBCL), being one of the major subtypes of non-Hodgikin’s lymphoma, is marked by extranodal involvement. In patients with DLBCL, the stomach and gastrointestinal tract are commonly involved, but few cases have reported the involvement with the middle ear cavity and temporal bone. The present study reports a patient diagnosed with DLBCL characterized by middle ear cavity involvement. We also reviewed other similar cases in the literature.

Fibrovascular polyps are rare benign intraluminal tumors that usually arise from the cervical esophagus. These often present as very large sized pedunculated polyps and cause symptoms including dysphagia and respiratory distress. Generally, large polyps are surgically excised, while endoscopic resection is limited to smaller polyps. Herein, we present a giant fibrovascular polyp of the esophagus treated successfully by endoscopic resection.

Adirect intracranial operative approach with clipping the neck of the aneurysm is generally considered to be the ideal treatment for the intracranial arterial aneurysms. Several strategies exist for treating unclippable aneurysms. Intravascular techniques, proximal occlusion of the parent artery or trapping of the aneurysm, microsurgical bypass of the involved arterial segment, and reinforcement or wrapping of the aneurysmal wall are frequently used. The authors report a case with long term(6 years) follow-up results of the circumferential wrapping with sutures-reinforcement for giant fusiform aneurysm of the internal carotid artery. The giant fusiform aneurysm and ideal wrapping materials were discussed with review of literature.
