Cavernous hemangioma is the most common primary tumor occurred in adults' orbit. This tumor has symptoms characteristically developing over several years with slowly progressive proptosis, eyeball deviation, hyperopia, diplopia and optic nerve compression. It's removal, necessary when there is progressive exophthalmos and visual deficit, is best performed en bloc to avoid intraoperative vleeding, the risk of residue, and potential further growth. In principle, surgical approach to the orbit must provide maximum safety and optimal visualization. The noncompressibility of the globe imposes greater demand on the need for some removal of the osseous orbit for surgical approach. This also must permit immediate functional and aesthetic reconstruction. The authors have experienced a case of large cavernous hemangioma in the orbit inferomedially. The surgical treatment of tumor was achieved by inferomedial approach combined with inferolateral orbitotomy. This surgical approach allows better visualization of the tumor and greater protection of essential anatomic structures. This also permits immediate functional and aesthetic reconstruction. So we present our case with a brief review of the literature related to orbital cavernous hemangioma.

Many plastic surgeons have been tried to attain ultimate goal lies in restoring the original shape and function of the facial aesthetics, in reconstruction of deformities resulting from facial hypertrophic scar and skin defects. This would require consideration in terms of hanmony in color match, skin texture and thickness. Various forms of skin graft, local flap, distant flaps, free flap and tissue expander have been employed in restoring skin defects and deformities of the cheek and submental area, and the use of large local flaps utilizing the cervicofacial skin flaps or tissue expander have brought about improved aesthetic results. the authers have obtained satisfactory results in treating 2 cases of wide hypertrophic scar of the cheek and submental area with combination of wide cervical flap and intraoperative tissue expansion using foley catheter. the merits of this combined operative methods are as follows : 1. It is not necessory to keep tissue expander for a long period. 2. This technique is able to diminish the cost of multistage operation and using of tissue expander. 3. There is no psychologic problems due to undesirable facial appearance during tissue expansion period. 4. Rapid intraoperative tissue expansion by foley catheter during elevating wide cervical flap can allow to dissect one, preserving the perforators without bleeding in a short time. 5. Wide cervical flap and additional expanded tissue by means of intraoperative tissue expansion could brought into suturing avoiding tension of oral commissure and lip eversion. 6. Preservation of perforators of cervical flap above the platysma muscle raised flap's survival rate and then this result could prevent distal ischemic necrosis after flap coverage.

PURPOSE: To assess the diagnostic usefulness of multimodality study in the diagnosis of breast cancer. MATERIALS AND METHODS: Eighty-one patients between January 1998 to December 1999 were involved in this study, and who underwent mammography, breast ultrasonography, and 99mTc-MIBI scintimammography in all cases the findings were retrospectively reviewed. Each modality was graded by two physicians specializing in nuclear medicine and two radiologists, all unaware of the pathologic results. A four-grade system(1=definitely benign, 2=probably benign, 3=probably malignant, 4=definitely malignant) was applied to those ofbreast ultrasonography and 99m Tc-MIBI scintimammography and BIRADS was applied to those ofmammography. All breast masses were confirmed by surgery (n=67) or FNA (n=14). Findings of grade 3 or 4 the four-grade system, BIRADS category 4 or 5, or positive coincidence in double and triple combination studies were defined as positive results, and on the basis of the data thus obtained, the sensitivity, specificity, positive and negative predictive value and diagnostic accuracy were calculated for each modality and for multimodality studies. RESULTS: The sensitivity, specificity, positive predictive value, negative predictive value and diagnostic accuracy of 99mTc-MIBI scintimammography were 83.6%, 88.5%, 93.9%, 71.9% and 85.2%, respectively. For ultrasonography, the corresponding figure were 94.5%, 65.3%, 85.2%, 85.0%, and 85.2%, and these for mammography, they were 87.3%, 69.2%, 87.3%, 81.8% and 80.2%. For the ultrasonography and mammography combination, the figures were 83.6%, 50.0%, 93.9%, 100.0% and 95.2%, respectively, and for 99mTc-MIBI scinti-mammography and mammography, the corresponding findings were 72.7%, 69.2%, 95.2%, 100.0% and 96.7%. For the 99mTc-MIBI scintimammography and ultrasonography combination, respective findings of were 80.0%, 61.5%, 95.7%, 94.1% and 95.2%, respectively, and in the triple modality study, respective findings of 70.9%, 50.0%, 97.5%, 100.0% and 98.1% were recorded. CONCLUSION: Among multimodality studies, sensitivity was greatest in the ultrasonography and mammography combination, which is thus extremely suitable for the diagnosis of breast cancer. The findings of two series suggest that in equivocal cases, 99mTc-MIBI scintimammography with its higher specificity and positive predictive value, is a useful adjunctive tool.

Heterotopic pregnancy is the coexistency of intrauterine and extrauterine pregnancy. The incidence of heterotopic pregnancy is about 1 to 30,000 pregnancy in a natural cycle. However, the frequency of heterotopic pregnancy has steadily increased because of rising incidence of pelvic inflammatory disease, pelvic surgery and the development of ovulation induction and assisted reproduction. Because heterotopic pregnancy is difficult to diagnose and it has high morbidity and mortality rate, one should always take this into consideration and should conduct careful and thorough gynecologic evaluation. We have experienced a case of heterotopic pregnancy in a 29-year old woman who presented with acute abdominal pain in a natural cycle and report this case with a brief review of literature.

The authors analyzed ultrasonographically the total 45 cases of thyroid disease verified by historicaldiagnosis, functional diagnosis, and morphological diagnosis at the Departement of Radiology, Busan NationalUniversity hospital from June to Sept. 1982. The resuls obtained were as follows; 1. In the sex distributionfemale was 38 cases (84.4%), and male 7 cases (15.6%). 2. Among the total 4 cases thyroid adenoma was 24 cases(53.3%), nodular hyperplasia 8 cases (17.7%), thyroid carcinoma 7 cases (15.6%), diffuse hyperplasia 3 cases(6.7%), Hanshimoto's thyroiditis 1 cases (2.2%), subacute thyroiditis 1 cases(2.2%), tuberculous thyroiditis 1cases(2.2%) in orders. 3. On ultrasonogram, total 24 cases of thyroid adenoma showed a single nodule in 24 cases(100.0%), smooth outer margin in 23 cases (95.8%), capsular echo in 23 cases (95.8%), pure cystic nodule in 4cases (16.7%), and increased echogenicity in 17 cases (85.0%) among the 20 cases excluded the pure cystic nodules.4. Total 7 cases of thyroid carcinoma showed no capsular echo in 4 cases (57.1%), irregular outer margine in 4cases(57.1%), no pure cytic nodule in all cases, and enlargement of metastatic lymphnode in 4 cases (57.1%). 5.Total 8 cases of nodular hyperplasia showed enlargement of thyroid gland and multiple nodule in 8 cases (100.0%),and increased echogenicity in 7 cases (87.5%). 6. Total 3 cases of diffuse hyperplasia showed enlargement ofthyroid gland and increased echogenicity in 3 cases (100.0%). 7. Total 3 cases of thyroiditis showed decreasedechogenicity in 3 cases (100.0%) and enlargement of thyroid gland in 2 cases (66.7%). 8. The cold area visualizedon radionuclide scan could be differentiated from a solid mass and cystic one by utrasonogram.
