Fractures of the femoral neck in children are rare and usually severe violence to occur, which accounts for the high frequency of associated injuries. Since the femoral neck in children has many anatomic and physiologic differences, not only are there many difficulties during the treatment period, but complications such as post-traumatic coxa vara, avascular necrosis of the femoral head, and premature epiphyseal closure may occur, sixty-two cases in sixty patients of fractures of the femoral neck in children which were treated at Severance Hospital, Yonsei University College of Medicine from Jan. 1971 to Dec. 1987 and at Young-Dong severance Hospital, Yonsei University college of Medicine from May. 1983 to Dec. 1987 were analyzed both clinically and radiologically. The following results were obtained: l. Of the 62 cases, the ratio of boys to girls was approximately 2:1 and the highest incidence was between 4 to 6 years old. 2. The main cause of fracture was traffic accidents, which occurred in 33 cases(53.2%). 3. According to the classification of Delbet and Colonna, the cervicotrochanteric fracture was the most common type(41.9% of the cases) and 29 cases(46.8%) were displaced fractures. 4. Thirty two cases(51.6%) were treated by conservative treatment and twenty eight cases (45.2%) by closed reduction and internal fixation. 5. Common associated injuries were genito-urinary tract injury, soft tissue injury, long bone fracture and pevic bone fractures. 6. All cases were followed for from 14 months to 15 years, average 8 years. 7. The results were analyzed according to Ratliff's assessment and 41 cases(66.1%) showed good results. 8. The total number of cases with complications was 33(53.2%). The most common complication being coxa vara and premature epiphyseal closure(32.2%). 9. Secondary treatment was done in 7 cases and correction osteotomy was done in 4 cases which had showed a good results. The authors found that for the treatment of type IV fractures, closed reduction followed by plaster of Paris immobilization was adeguate but for type I, II, III after early closed reduction, internal fixation was performed as soon as possible using threaded pins as the internal fixation device. The results were poor in type I and type II, fractures with severe displacement, and in cases in which the treatment was delayed due to associated injury.

6.Huge Hepatic Angiomyolipoma Mimicking Low Grade Hepatocellular Carcinoma

A 41-year-old man was diagnosed with a huge symptomatic liver mass and was referred to our hospital for liver biopsy and further evaluation. He presented with right upper quadrant tenderness. Enhanced abdominal computed tomography and magnetic resonance imaging revealed a 12.5-cm relatively well-defined heterogeneous enhancing mass in the right inferior liver with a large exophytic component containing a fat component and progressive delayed enhancement. The patient underwent right inferior sectionectomy. The pathological diagnosis was confirmed as angiomyolipoma, 12.3×9.2×5.0 cm in size, with tumor necrosis in 20% of the tissue. Hepatic angiomyolipoma is known as a benign tumor, but in our case, because of the large tumor size and coagulative necrosis, this tumor had malignant potential; surgical resection was deemed to be appropriate, and close follow-up monitoring was essential postoperatively.

Meckel diverticulum is the most common congenital abnormality of the small intestine. The condition occasionally involves invagination of the bowel lumen, leading to intussusception. We report a case in which intussusception secondary to an inverted Meckel diverticulum, together with an ectopic pancreas, occurred in an adult, and describe the associated radiologic, clinical and pathologic findings.

PURPOSE: To analyse the MR imaging characteristics of the soft tissue hemagiomas of the extremity. MATERIALS AND METHODS: We retrospectively reviewed histopathologically proven 18 cases of hemangiomas of the extremity including 15 cavernous hemangiomas, 2 venous hemangiomas and 1 capillary hemangioma. The lesions were frequent in female and low extremity. We analyzed the site, extent, margin, signal intensity, enhancement pattern, the homogeniety of internal architecture, and abnormal vessels near the lesion. RESULTS: The extensive lesions involving multiple muscle and tissue layers were more frequent than localized lesions (12/18). Twelve cases had ill defined margin. In most cases, the lesion was heterogeneous mass composed of nodular and septal components. The nodular component showed intermediate signal intensity in T1WI and hign signal intensity in T2WI. The setal component showed mixed inconstant signal intensity. One case of capillary hemangioma showed relatively homogeneous signal intensity than cavernous hemangioma and the main portion of 2 venous hemangiomas had mutilple tubular signal voids. At least some portion of the lesion was enhanced in all enhanced cases. CONCLUSION: The soft tissue hemangiomas of the extremity showed characteristic MR findings and MRI would be an useful method in the diagnosis of the soft tissue hemangiomas of the extremity.
