The coracoclavicular joint is a rare genetical anatomic variants. The joint occurs at the junction of a bony projection extending inferiorly form the outer third of the clavicle at the site of the conoid tubercle and a bony projection extending superiorly form the coracoid process of the scapula. In our study we reviewed the radiological incidence of the coracoclavicular joint in Korean adults. The materials consist of 4,625 routine chest films, 9,250 sides. Sex distribution were 3,000 males and 1,625 females. The authors observed coracoclavicular joint on 17 persons (0.37%) and 25 sides (0.26%) and among them, 8 persons (47%) were bilateral and in 9 (53%) it was unilateral. The joint when unilateral occures frequently on left side, and there was no significant sex difference. There were statistically significant differences in the incidence of coracoclavicular joints among Korean, Japanese and Chinese.

The majority of injections intended to be intramuscular are actually delivered into fat in the area of thebuttock in most of the patients having a thick gluteal fat layer. Injections of some drugs can cause tissuenecrosis that ensues in scar formation and often in dystrophic calcifiation giving rise to ring-like densities inantero-posterior radiographs of the pelvis. We studied the incidence and characteristics of calcifications in thebuttocks frequently noted in pelvic radiographs and whether they have any relationship with thickness anddistribution pattern of the fat layer in the buttocks. Pelvic radiograms of 220 consecutive patients (110 malesand 110 females) with the age ranging from 16 to 76 years(average 39) were reviewed. The area of buttock was divided arbitrarily into four quadrants by the vertical line crossing the center of the head of each femur and thehorizontal line connecting the summit of each femoral head, and the upper outer quadrant was further divided into four quadrants(Fig. 1). We measured the thickness of the extraperitoneal fat layer at the level where it cross theiliac crest bilaterally. The results were as follows; 1. Thirty out of 220 cases(14%) showed calcifications in thebuttock. 2. Calcifications in the buttock were much more frequent in female than in male (p<0.01). 3. Theincidence of calcifications increased with age(P<0.01) and with increase in fat layer thickness(P<0.01). 4,Calcifications in the buttock were mostly located at the upper outer quadrant of the buttock (78%). 5. Inconclusion, we assume that calcifications in the buttock are result of fat necrosis after injection into fatinstead of muscle.

Chordoma is relatively rare and slowly growing tumor arising from notochordal remnant. The tumor is locally infiltrative rather than metastatic. Distant metastasis occured in 5% of Gentil & Coley's cases and 43% of Higinbotham et als cases. Usual sites of metastasis sites were lung, liver adrenal gland and lymph nodes. In 1922, Stewart reported first case of extrapulmonary metastatic chordoma in muscle & subcutaneous layer, which was extremely rare. We have experienced a case of wide spread multiple metastasis to muscle & subcutaneous tissue from primary sacrococcygeal chordoma. The case was 26 years old man, who have had multiple metastatic lesions in trunk, upper & lower extremities. They located in muscle and subcutaneous fat layer. In some lesions neurovascular structure was involved. We have treated the metastatic lesions by complete surgical excision, and they were confirmed as soft tissue chordoma by histologic examination.

Visualization of falx cerebri on non-enhanced CT of children with severe head injuries (the falx sign) has been regarded as an evidence of subarachnoid hemorrhage. On the contrary, other authors have reported reverse results. To evaluate clinical significance of the falx sign, authors studied frequency of visualization and CT number of falx cerebri and dural sinuses in 65 children with head injury and 65 children without head injury examined by cranial CT at the Dep. of Radiology, St. Paul's Hospital, Catholic Medical College from March to Sept. 1981. All patients with head trauma were studied within 1 week of the traumatic event. Visualization of falx cerebri was observed at slice in the region of lateral ventricle and slice near to vertex respectively. On the slice in the region of lateral ventricle, falx cerebri was identified in 82% of all of the children examined, of which 92%showed partial visualization of falx cerebri and remaining 8% totally. On the slice near to vertex, falx cerebri was identified in 92% of all the children examined, of which 38% showed partial visualization of falx cerebri and remaining 62% totally. In head trauma group, frequency of visualization of falx cerebri was 78% on the slice in the region of lateral ventricle and 89% on the slice near to vertex; in non-traumatic group, frequency of visualization of falx cerebri was 86% and 94% respectively. The highest numerical value of the falx densities averaged 47 Hounflieds (range, 32-63) in non-traumataic group, averaged 49 Housfields (range, 32-69) in head trauma group. All or a portion of the superior sagittal sinus was visualized in 59% of all of the cases studied, 50% in head trauma group, and 69% in nontraumatic group. The straight sinus was identified in 45% of all of the cases studied, 39% in head trauma group, and 51% in non-traumatic group. In conclusion, there was no distinction between head trauma and non-traumatic group in visualization of falx cerebri and dural sinuses, and we could frequently identify the falx density in normal. Also we could find that frequency for visualization of falx cerebri and drual sinuses increased as the age increased.

Thymic size can be affected by both exogenous and endogenous glucocorticoids. Development of the respiratory distress syndrom (RDS) is influenced by adernal cortical function. thus, thymic size in RDS is considered to been larged due to decreased adrenal cortical function. To find whether the presence of RDS correlates with thethymus, the size and shape of the thymus were evaluated in the radiographs of premature infants with RDS, without RDS(control prematurity) and normal infants. The subjects were consisted of chest films of Korean premature infants, 120 with RDS, 60 without RDS, and 60 of normal infants taken at the Departement of Radiology, Our Lady of Mercy Hospital during the period of 62 months since January 1978. Relative size of the thymus was determined bycardiothymic/thoracic ratio(CT/T ratio). Grading and locaiton of the thymic prominence as well as incidence of the shape were examined. And all the relations among the radiographs of RDS, control prematurity and normal infants were analyzed. The results were as follows; 1. The CT/T ratio of premature infants with RDS was significantly greater than that of control prematurity and normal infants (P<0.01). 2. The incidence of bilateral thymicprominence was more frequent in premature infants with RDS than in control prematurity and normal infants(P<0.05).3. The frequency of thymic prominence was greater in the right than left side in all the three groups (P<0.05). 4.As in the shape of the thymus, a rounded type was most frequent, and a triangular type was least frequent in allthe three groups. 5. Incedence of RDS was very low(9.8%) when the CT/T ratio is below 0.3 and it was very high(90.9%) when the CT/T ratio is above 0.49.

PURPOSE: CD24 is a small, heavily glycosylated glycosylphosphatidylinositol-linked cell surface protein that is expressed in hematologic malignancies and in a large variety of solid tumors. It appears to function as a ligand of P-selectin, an adhesion molecule that is present in activated platelets and endothelial cells. We aimed to evaluate CD24 protein expression in adenomas and adenocarcinomas of the colon and to correlate it to clinicopathological data. METHODS: Adenomas and adenocarcinomas of the colon were stained for CD24 immunohistochemically. For statistical analysis, the staining was categorized according to stainability (negative, weakly, moderately, strongly positive) and staining patterns (membranous vs. intracytoplasmic). RESULTS: The present study clearly demonstrated that CD24 was much more abundantly expressed for adenocarcinomas than for adenomas in the colon (P <0.05). A higher significant association of cytoplasmic CD24 expression was observed with adenocarcinomas of the colon than with adenomas of the colon (P <0.05) and with positive nodal status of the colonic adenocarcinoma than with negative nodal status of the colonic adenocarcinoma (P <0.001). CONCLUSIONS: The stainability and the staining pattern of CD24 is an important molecular marker for colonic epithelial neoplasms and may help to define malignant transformation and to predict lymph-node metastasis.

PURPOSE: Sulphomucin is secreted by immature foveolar cells of the stomach and is expressed in gastric adenocarcinomas. Carcinoembryonic antigen (CEA) is well known to be expressed in gastric adenocarci nomas and is correlated with the cellular differentiation of gastric adenocarcinomas. However, at the moment, there are no conclusions about the relationships between the expression of sulphomucin and pathological classifications. METHODS: This study was designed to determine the significance of expression of sulphomucin and CEA in advanced gastric adenocarcinomas. Also, these two factors were compared with established clinicopathological prognostic factors. Thirty-two paraffin-embedded surgical specimens of gastric adenocarcinomas were obtained from January 1993 to December 1995 and were selected for study. The expressions of sulphomucin and CEA were studied by using the Spicer method and immunohistochemical staining with CEA 2-7 monoclonal antibody. RESULTS: The expressions of sulphomucin and CEA were positive in 9 (28%) cases and 25 (78%) cases, respectively. There was a significant correlation between sulphomucin expression and histologic differentiation (p<0.05). However, the expression of CEA was correlated with neither clinopathological factors nor sulphomucin expression. CONCLUSION: These results suggest that expressions of sulphomucin are well correlated with cellular differentiations of advanced gastric adenocarcinomas.
