Positron emission tomography (PET) with 2-[F-18]-Fluoro-2-deoxy-D-glucose (FDG) was performed in ninteen patients who had benign musculoskeletal tumors in order to determine if there was a relationship between histologic grade of tumor and FDG uptake of tumor. These patients had been evaluated previously with computed tomography (CT) or magnetic resonance (MR) imaging or both. The diagnoses were confirmed with incisional or excisional biopsy or by radiographic follow-up. Generally high-grade tumors had significantly greater uptake of FDG than low-grade lesions . Benign lesions such as giant cell tumor, fibrous dysplasia, and osteofibrous dysplasia showed significant elevation of SUV (Standardized Uptake Value) above 4.0. On the contrary. The current studies suggest the utility of FDG-PET imaging as an adjunct to CT or MR imaging in the evaluation of benign tumors. And results of PET suggest benign tumors with high SUV are histologically active lesion and tend to be locally aggressive.

Bile duct necrosis and liver abscess are rare complications after transcatheter hepatic arterial embolization (THAE) of hepatocellular carcinoma. Authors report bile duct necrosis and liver abscess occurred in 2 cases as a complication of THAE of hepatocellular carcinoma. In these two patients, lipiodol emulsion mixed with adriamycin and mitomycin was used more than three times as chemoembolic materials.

PURPOSE: Choroid Plexus papilloma is a rare intracranial neoplasm that is most commonly found in the trigone of the lateral ventricle in children or in the fourth ventricle in adult. Extraventricular extension of choroid plexus papilloma has been rarely reported within the cerebellopontine angle (CPA) cistern. Authors report two cases of choroid plexus papilloma in the posterior fossa seen on magnetic resonance imaging (MRI). MATERIALS AND METHODS: MRI findings of two cases of choroid plexus papilloma in posterior fossa were retrospectively reviewed. RESULTS: In the first case, the tumor was in the fourth ventricle and extended to the left CPA cistern via the foramen of Luschka. In the second case, the tumor presented as an expansile mass of the of fourth ventricle and right lateral recess. Multiple signal voids of low intensity due to prominent feeding vessels and calcifications within the tumors were noted. CONCLUSION: This report demonstrates MR findings of choroid plexus papilloma in the posterior fossa with the brief review of the literatures.

Magnetic resonance imaging (MRI) was used to study Mayer-Rokitansky-Kuster-Hauser (MRKH) syndrome in two 21-year-old women. In one case MRI revealed that fluid filled an area of the uterus measuring about 4 x 4cm, but that the ovaeies were normal ; in the other case, a rudimentary uterus and normal ovaries were seen. MRI is useful both in the planning of surgical management and in evaluating the details of pelvic anatomy and uterine morphologic characteristics.

Sclerosing encapsulating peritonitis is a well recognized, but uncommon, complication of chronic ambulatoryperitoneal dialysis, I report a case of sclerosing encapsulating peritonitis in which percutaneous catheterdrainage was performed preoperatively. Ultrasonography(US) and computed tomography(CT) showed a largemulti-septated cystic mass which occupied nearly all the peritoneal cavity. Percutaneous drainage with two 8.5French catheters was preoperatively performed under fluoroscopy and about 2100ml of bloody fluid was drained for20 days. On follow-up CT, the size of the cyst had significantly decreased and an operation was performed. It isconsidered that percutaneous catheter drainage is useful in the preoperative decompression of sclerosing encapsulating peritonitis.
