Fifty two cases of displacecd supracondylar fractures were divided into three groups according to the methods of fracture stabilization. Cast immobilizations without pin fixation were included to the group 1 (12 cases), fixation with lateral pins to the group 2 (22 cases), and lateral and medial cross pins to the group 3 (18 cases). In each group we attempted a radiological analysis for the stabilization failure through measurements of the horizontal rotation and the mediolateral tilting in their preoperative, postoperative and follow-up X-rays. Stabilization failure during the follow-up period was presumpted to be present in those cases that show (1) a development or increase of the horizontal rotation in follow-up lateral X-ray, and (2) accompanied change in Baumann's angle of more than 5 degrees. The failed stabilizations were in three cases (25%) in the group 1. In the group 2 the horizontal rotations after initial fixation were developed in four fractures. However, only two (9%) of the four cases accompanied significant changes in the Baumann's angle. Loss of the initial fixation in the cross pin group was found in one case. These results demonstrate that the cross pin fixation is the most stable form. Fixation in only lateral side sometimes shows rotational instability, but this method seems to be still useful because singificant coronal tilting develops in only a few occasions of those with horizontal rotation.

Intraventricular cysticercosis is the rest form of cerebral cysticercosis and almost all are within the fourthand third ventricles. Authors have experienced a case of pathologically proven giant intraventricular cysticercalcyst involving the lateral ventricle, studied by conventional CT and metrizamide CT, and report with brief reviewof literature.

The diagnosis of ovarian tumor has been mainly dependent on manual pelvic examination and ultrasonography. Butin case of malignant ovarian tumor, CT has more advantages over ultrasonography in assessing anatomic details,relationships to bowel loops, precise extents of tumors and follow-up examinations after surgery. Authors analyzedCT features of 46 cases of patholgocially proven ovarian tumors for recent 4 years at keimyung University DongsanHospital. The results were as follows: 1. The msot common tumor was serous cystadenocarcinoma(9 cases:20%),followed by metastases(8 cases: 17%), mucinous cystadenocarcinoma(7 ases:15%), mucinous cystadenocarcinoma(5cases:11%), teratoma(5 cases:11%), lymphoma(3 cases: 7%) and dysgerminoma(2 cases:4%). 2. The ovarian tumors werevariable in size from 2.5cm to 33cm in diameter. Most of the solid tumors were smaller than 10cm in diameter andmost of the cystic tumors were larger than 10cm in diameter. Usually mucinous tumors were much larger than seroustumors. Mucinous cystadenomas were the largest tumors. 3. Unilateral tumors(left 19,right 13 cases) were morecommon than bilateral tumors(12 cases). Bilateral tumors were seen in serous and mucinous cystadenocarcinoma,metastases and lymphoma. 4. CT features of mucinous cystadenomas were smooth margins and thin wall of the tumormasses and multiloculated cysts with internal septa in all 7 cases. 5. In contrast, CT demonstration ofbilaterality, irregular margin, thick wall, enhancing solid lesions, septal irregularity, adhesion to adjacentstructures, peritoneal/omental implantation, ascites and hydronephrosis were signs suggesting malignancy. CTfeaturs of the serous cystadenocarcinoma were mostly solid to mixed nature(83%), irregular margin(75%), enhancingsolid lesion(67%), papillary growth (75%), internal septa(58%), multilocularity (58%) and calcification (25%) indescending order of frequency. 6. On CT, mucinous cystadenocarcinoma were irregular-marginated, thick-walled,cystic tumors with enhancing solid lesion, septal irregularity and signs of metastasis, although there were somecases having similar features of benign. 7. Among the extrapelvic CT findings of malignant epithelial ovariantumor, peritoneal/omental implants(11 cases:79%) and ascites(10 cases:71%) were the most common, and indistinctuterus(6 cases:43%), bowel adehsion(5 cases:36%) and pseudomyxoma peritonei (2 cases) were descending order offrequency. 8. CT features of teratoma were diagnostic having at least three more of different tissue densitiesamong fat, water, soft tissue and calcific densities. Also there were thick wall (4 cases) and fat-fluid level(1case). 9. In 8 cases of ovarian metastases, there were solid type tumor smaller than 10cm in 4 cases and hugecystic in 2 cases. The site of primary cancer were stomach in 4 cases, colon , cervix, endometrium and unknown ineach one case. 10. In 3 cases of malignant lymphoma, the CT featurs were solid in appearance, smaller than 10cmand accompanied by lymphadenopathy in all cases.
