Cardiac lymphangioma is one of the rarest, primary, benign tumor of the heart. We report a case of cardiac lymphangioma, which was diagnosed with CT and MRI in a 50 years old female. Plain chest film showed minimal enlargement and globular shape of the heart. On CT scan, abnormal fluid density mass lesion was noted within pericardial sac. The signal intensity was lower on T1-weighted image and hgher on T2-weighted image than that of the myocardium and located along the left atrioventricuar groove. Several small low signal spots representing hemorrhage were seen within this lesion.

PURPOSE: To evaluate the treatment outcome for Type A2 or above intertrochanteric fractures in elderly patients using cementless bipolar hemiarthroplasties incorporating a standard (tapered, rectangular) stem. MATERIALS AND METHODS: We retrospectively reviewed the records of 37 patients who had undergone bipolar hemiarthroplasty between February 2006 and February 2010 in our hospital, and who had received follow up evaluation for more than two years after the surgery. The mean patient age was 73.5 years (range 65-88 years), and 16 patients were male and 21 were female. We evaluated the the results of their treatment by analyzing the operation duration, volume of bleeding, measured results for the recovery of walking capability, and any complications and radiologic findings. RESULTS: The mean operation duration was 75.3 minutes(50-185 minutes). The average total volume of bleeding was of 755.5 cc(75-1,400 cc). Upon the final follow-up visit, 27 patients(72.9%) had recovered more than 80% of their pre-injury Barthel index values(72.8+/-15.1). Complications included one case of deep infection, one case of acetabular erosion, and 3 cases of greater trochanter non-union. There were no cases of revisions due to prosthesis loosening or for other reasons. CONCLUSION: Cementless bipolar hemiarthroplasty using a tapered, rectangular stem is a viable alternative treatment for type A2 intertrochanteric fractures in elderly patients which supports rapid patient mobilization ability.

Adult intussusception is rare involving of only 1% of the causes of bowel obstruction. We report a case of a 39-year-old female with intussusceptions due to inverted Meckel's diverticulum. She visited our hospital for diffuse abdominal pain during 1 week and aggravated abdominal pain for 2 days. Vital signs were stable, and there was periumbilical tenderness. She had no history of abdominal operation. CT scan showed a 3.7x2.1 cm of fatty mass with focal intussusception in the distal ileum. When the emergency operation was performed, the patient was found to be suffering from ileocolic intussusception. A manual reduction of intussusception showed inverted Meckel's deverticulum at 65 cm proximal to the ileocecal valve, and the segmental resection of small bowel including a Meckel's diverticulum was performed. Pathologic examination revealed a Meckel's diverticulum containing a 0.6x0.6 cm sized aberrant pancreas.

PURPOSE: The purpose of this study was to measure the buccal bone thickness and angulation of the maxillary incisors and to analyze the correlation between these parameters and the root position in the alveolar bone using cone-beam computed tomography (CBCT). MATERIALS AND METHODS: CBCT images of 398 maxillary central and lateral incisors from 199 patients were retrospectively reviewed. The root position in the alveolar bone was classified as buccal, middle, or palatal, and the buccal type was further classified into subtypes I, II, and III. In addition, the buccolingual inclination of the tooth and buccal bone thickness were evaluated. RESULTS: A majority of the maxillary incisors were positioned more buccally within the alveolar bone, and only 2 lateral incisors (0.5%) were positioned more palatally. The angulation of buccal subtype III was the greatest and that of the middle type was the lowest. Most of the maxillary incisors exhibited a thin facial bone wall, and the lateral incisors had a significantly thinner buccal bone than the central incisors. The buccal bone of buccal subtypes II and III was significantly thinner than that of buccal subtype I. CONCLUSION: A majority of the maxillary incisor roots were positioned close to the buccal cortical plate and had a thin buccal bone wall. Significant relationships were observed between the root position in the alveolar bone, the angulation of the tooth in the alveolar bone, and buccal bone thickness. CBCT analyses of the buccal bone and sagittal root position are recommended for the selection of the appropriate treatment approach.

Imaging Science in Dentistry 2022;52(4):415-419
A central odontogenic fibroma is a rare benign tumor composed of mature fibrous connective tissue with variable amounts of odontogenic epithelium. It appears at similar rates in the maxilla and mandible. In the maxilla, it usually occurs anterior to the molars. Radiographically, central odontogenic fibroma commonly presents as a multilocular or unilocular radiolucency with a distinct border. This paper reports a case of an aggressive central odontogenic fibroma involving the right posterior maxilla of a 53-year-old man. Radiographs showed an extensive soft tissue mass involving the entire right maxilla with frank bone resorption. The patient had a history of 2 operations in the region, both more than 2 decades ago. Although it was impossible to confirm the previous diagnoses, it was presumed that this case was a recurrent lesion.

Imaging Science in Dentistry 2022;52(4):365-373
Purpose:
This study investigated whether the relationship between the maxillary sinus and the root of the maxillary premolar is correlated with the root position and whether there is a difference in the long axis angle of premolars and the buccal bone thickness according to the sinus-root relationship and root position.
Materials and Methods:
Cone-beam computed tomographic images of 587 maxillary first premolars and 580 second premolars from 303 patients were retrospectively reviewed. The maxillary sinus floor-root relationship was classified into 4 types, and the root position in the alveolar bone was evaluated as buccal, middle, or palatal. The long axis angle of the maxillary premolars in the alveolar bone and the buccal bone thickness were measured. The correlation between these parameters was analyzed.
Results:
The maxillary sinus floor-root relationship showed a statistically significant correlation with the root position in the alveolar bone. Most maxillary first premolars were buccally located, and more than half of the second premolars had their roots in the middle. The long axis angle of the premolars was significantly larger in buccal-positioned teeth than in middle-positioned teeth, and the buccal bone was thinner.
Conclusion
When the root of the maxillary premolar was separated from the sinus floor, the premolar was often located on the buccal side. Most of the maxillary first premolars had a thinner buccal bone and larger inclination than the second premolars. It is recommended to evaluate the root position, sagittal angle and buccal bone thickness using CBCT for implant treatment planning.

Imaging Science in Dentistry 2020;50(4):359-363
Ameloblastic carcinoma is a rare odontogenic malignant tumor with the histologic features of both ameloblastoma and carcinoma. It occurs more frequently in the mandible than in the maxilla and it may appear de novo or develop from a preexisting ameloblastoma or odontogenic cyst. Rapidly progressing, painful swelling is the most common symptom, and radiographically, it shows significant bone resorption and cortical perforation. This report described a case of ameloblastic carcinoma in a 45-year-old man who presented with swelling in the left mandible. The lesion showed combined features of benign findings, such as an expansile cortex with a distinct border, and malignant findings, such as a large exophytic mass with frank bone resorption. Excisional biopsy was performed and a final diagnosis of ameloblastic carcinoma was made.

Purpose:
This study investigated correlations between findings on panoramic radiographs and cone-beam computed tomography (CBCT) to assess the relationship between the maxillary sinus floor and the roots of maxillary posterior teeth. In addition, radiographic signs indicating actual root protrusion into the maxillary sinus were evaluated on panoramic radiographs.
Materials and Methods:
Paired panoramic radiographs and CBCT images from 305 subjects were analyzed. This analysis classified 2,440 maxillary premolars and molars according to their relationship with the maxillary sinus floor on panoramic radiographs and CBCT images. In addition, interruption of the sinus floor was examined on panoramic radiographs.
Results:
Root protrusion into the maxillary sinus occurred most frequently in the mesiobuccal roots of the second molars. The classification according to panoramic radiographs and CBCT images was the same in more than 90% of cases when there was no contact between the root apex and the sinus floor. When the panoramic radiograph showed root protrusion into the sinus, the CBCT images showed the same classification in 67.5% of second molars, 48.8% of first molars, and 53.3% of second premolars. There was a statistically significant relationship between interruption of the sinus floor on panoramic radiographs and root protrusion into the sinus on CBCT images.
Conclusion
The presence of root protrusion into the sinus on panoramic radiographs demonstrated a moderate ability to predict root protrusion into the maxillary sinus. Interruption of the maxillary sinus floor could be considered an indicator of actual root protrusion into the maxillary sinus.

BACKGROUND: Women smoker faces increased risk for heart disease, stroke, cancers, and respiratory diseases as well as a number of gender specific risks. Maternal smoking has been linked to harmful effects on their offspring such as increased incidence of premature, stillbirth and sudden infant death syndrome, etc. Recently, the rate of female adolescent smoking in Korea is increasing, and the rate of adult woman is expected to increase. This study is aimed at obtaining basic information about smoking patterns and factors associated with smoking in Korean adult women. METHODS: From May 1995 to April 1999, a self-administered questionnaire was distributed to the female visitors of Health Promotion Center in Seoul National University Hospital. The number of smokers was 492. The control group(984 nonsmokers) was selected by 1:2 age group matched random sampling. Smokers and control group were divided into three age groups-young age(20-39 years), middle age(40-59 years), old age(60 years and over)-and analysed the resalts using SPSS and EpiInfo software. RESULTS: The most frequent amount of cigarette smoking was below 10 cigarettes in all age groups. The duration of smoking was below 10 years in most young and middle age groups. In the old age group the duration of smoking was longer than others. Variables positively associated with smoking included alcohol drinking, being engaged in trade service, being unmarried or divorced or separated or parted for ever, high stress status, dissatisfation of life in young age group. The variable of no exercise was added to them in middle age group. In old age group alcohol drinking, no exercise, no school education were the positive meaningful factors associated with smoking in multivariant logistic regression analysis. CONCLUSIONS: The modifiable variables associated with smoking in Korean adult women included alcohol drinking, high stress status, dissatisfation of life and no exercise.
