PURPOSE: To evaluate MR imaging findings of degenerating parenchymal neurocysticercosis and to determine the characteristics which distinguish it from other brain diseases. METHODS: MR imagings of 19 patients (56 lesions)of degenerating parenchymal neurocysticercosis were retrospectively evaluated, focusing on the size and locationof lesions, signal intensity patterns of cyst fluid and wall, the extent of the surrounding edema and features of contrast enhancement. RESULTS: Degenerating parenchymal neurocysticercosis was located in gray or subcortical white matter in 89.3% of 56 lesions(50/56); most of these (98.2%) were smaller than 2cm in diameter. Cyst fluidsignal was hyperintense relative to CSF on T1 and proton density weighted images (92.9%). A hypointense signal rimof the cyst wall was noted in the lesions on proton density (92.9%) and T2 weighted (98.2%) images. Surrounding edema was mostly mild. Peripheral rim enhancement was noted in all lesions, and this was frequently irregular and lobulated (67.9%) with a focal defect in the enhancing rim (41.1%). CONCLUSION: Findings which could be helpfulin distinguishing degenerating parencymal neurocysticerosis from other brain diseases are as follows : small, superficial lesions ; hyperintense signal of the cyst fluid on T1 and proton density weighted images ; hypointense signal of the cyst wall on proton density and T2 weighted images ; relatively mild extent of surrounding edema,and peripheral rim enhancement which is frequently irregular and lobulated with a focal defect in the enhancingrim.

Cyclopia is rare congenital craniofacial anomaly, in which the eyes are fused together and located in a single orbit. It is consistently associated with severe holoprosencephaly, which is the failure of cleavage of the prosencephalon with a deficit in the midline facial development. chromosomal study revealed 47, X( ), +13 (Patau syndrome).

Pituitary abscess is a rare condition of the pituitary gland. We report MR imaging findings in two cases of surgically-confirmed pituitary abscess occurring in women aged 39 and 28. In both a peripheral rim enhancing lesion, similar to abscesses in other areas of brain, was seen in the pituitary fossa.

Desmoid tumor (fibromatosis) is a histologically benign fibrous neoplasm showing locally infiltrating growth. This type of tumor commonly occurs in the abdomen, but intrathoracic desmoid tumor is uncommon. To date, 12 cases of intrathoracic desmoid tumor protruding into the pleural cavity, radiologically mimicking pleural masses, have been reported. Here, we report on a case of intrathoracic desmoid tumor protruding into the pleural cavity, and partially covered by parietal pleura. The main preoperative differential diagnoses included pleural solitary fibrous tumor, inflammatory pseudotumor or malignant mesothelioma. A near-total mass excision was performed. Pathologically, the tumor was composed of a paucicellular arrangement of spindle-shaped cells with fibromyxoid stroma. The resection margin was partially involved with spindle cells present. On histochemical staining, the spindle cells were strongly positive for vimentin and negative for CD34, consistent with a desmoid tumor. The patient was stable without further adjuvant treatment during 6-years of follow-up.

Gastric leiomyomas, which arise from smooth muscle tissue, are the most common non-epi- thelial tumors occurring in the stomach. This tumor is most commonly found incidentally at surgery or autopsy. The incidence of the leiomyoma is about 1-3% of all gastric tumors and sex distribution is equal. We have recently experienced a 59-year-old housewife who had epigastric pain and soreness of one month's duration. Physical examination disclosed tenderness with palpated mass in the left upper quadrant. Gastrofiberscopic finding revealed esophageal diverticulum in the mid-esophagus and 2 x 2 x 1 cm sized submucosal intramural mass with centrally depressed umbilication through ulcerative change on the greater curvature of lower body. Within the umbilication, there were food materials and blood clots. The sleeve segmental resection of stomach was performed. The histopathologic and post operative findings were atypical leiomyoma, perforated with abscess formation to the omentum.
