One hundred eighty-six cases of ovarian common "epithelial" tumor including 28 endometriosis were reviewed, from the pathology file of the department of pathology of the National Medical Center during a period of 8 years and 6 months from January 1976 to June 1984. The study consisted of 14 cases(77.4%) of benign tumor including 28 cases of ovarian endometriosis, and 21 cases(11.3%) of borderline malignancy and 21 cases(11.3%) of invasive malignant tumors. Among benign common "epithelial" tumors, mucinous cystadenoma(69 cases) was the most frequent tumor, followed by serous cystadenoma (42 cases) and Brenner tumor (5 cases). Of borderline tumor, borderline mucinous tumor (18 cases) was more frequent than serous tumor (3 cases). Serous cystadenocarcinoma(9 cases) was the most frequent malignant tumor, followed by mucinous cystadenocarcinoma(6 cases), endometrioid carcinoma(3 cases) and undifferentiated carcinoma(3 cases). Most ovarian common "epithelial" tumors were prevalent during the reproductive age, but malignant tumors were more prevalent after the age of 40. Although right side was more frequently found (85 vs. 67) there is no significant site predilection. Bilaterality was the most common in undifferentiated carcinoma(66.7%), followed by serous cystadenocarcinoma(44.4%) and Brenner tumor(40%). The size of tumor tended to be larger in malignant tumor than benign. Mucinous tumor were usually larger than serous tumor. There were 7 intrauterine and 1 ectopic tubal prognancy which were associated with ovarian common "epithelial" tumors. Three cases of tumors were excised during Cesarian section. In summary these findings are comparable to other reports in Korea and English literatures. Histologic analysis of borderline and malignant epithelial tumor was done to emphasize their biologic behavor. Further study is required to compare their histological grading and clinical staging with thier survival rate.

Cytomegalovirus(CMV) is the most common cause of congenital viral infections. CMV infection occurs in 0.4% to 2.4% of all live births. CMV causes thin cerebral cortices, diminished volume of white matter, and delayed myelination, bringing on encephalopathy, which may be manifested as seizures in some cases. CT findings in CMV encephalopathy present as irregular intracranial calcifications of the periventricular area. Recently, there are increasingly more reports about MRI findings in CMV encephalopathy and common findings of the encephalopathy are periventricular cysts and dilated lateral ventricles. We experienced a case of congenital CMV encephalopathy with patchy, nodular lesions of the periventricular area on magnetic resonance imaging(MRI). We report this case with a review of associated literature.

Malignant rhabdoid tumor (MRT) is a rare and highly aggressive neoplasm of infancy and childhood. Although it was originally described and most frequently reported in the kidney, it may occur in various extra-renal sites such as the liver, thymus, and soft tissue. In the last decade primary central nervous system (CNS) MRTs have been reported in both the supra- and infratentorial compartments. Patients with CNS MRT were generally below the age of two and reports in adults are extremely rare. This is a case of primary cerebellar MRT in a 24-year-old woman, who had presented with intermittent headache, vocal cord palsy, and cerebellar dysfunctions such as abnormal finger to nose test and tandem gait. By magnetic resonance imaging scan, a well-enhancing solid mass was demonstrated at the posterior fossa filling the 4th ventricle, which extended into the medulla and cervical cord via the foramen of Magendie. Histologically, the monotonous polygonal tumor cells were arranged in diffuse sheet with occasional hemorrhagic necrosis. The nuclei were vesicular and eccentrically located due to eosinophilic, PAS-positive, intracytoplasmic inclusions with prominent nucleoli. They were diffusely or focally immunoreactive for vimentin, neurofilament, cytokeratin, GFAP, synaptophysin, and smooth muscle actin, while epithelial membrane antigen and desmin were negative. Ultrastructurally, the polyhedral tumor cells were densely packed with primitive intercellular junctions. Scanty fibrillar intermediate filaments were intermingled with cellular organelles. Postoperatively, craniospinal irradiation and systemic chemotherapy have been done and she has been free of tumor recurrence during the 13 months' follow-up periods.
