PURPOSE: To determine the necessity of site-specific bone mineral density(BMD) measurement and the difference between the BMD of the two femora using DXA in the evaluation of osteoporosis. MATERIALS & METHODS: Total BMD and regional BMD(Lumbar spine, femoral neck, Ward's area, intertrochanter area) were measured on seventy-eight healthy persons without previons diseases, and the statistical significance analyzed. RESULTS: Total BMD did not reliably reflect the site-specific BMD. There was a high correlation between BMD in opposing femora. Correlation coefficients between the femoral neck, Ward's area, trochanter area were 0. 939, 0.874 and 0.916 respectively. CONCLUSION: We conclude that a measuremnt of site-specific BMD is necessory because the total BMD can not reliably predict the regional BMD. The measurement of BMD in one femur can predict the BMD of the contralateral femur. If there is no history of femoral neck disease, unilateral BMD measurement is recommended for femoral evaluation.

PURPOSE: To assess the MR findings of Tolosa-Hunt syndrome and to evaluat differential point of cavernous sinus lesions. MATERIALS AND METHODS: Eleven cases of Tolosa-Hunt syndrome were evaluated by MRI with specific regard to the shape of cavernous sinus, signal intensity, and pattern of enhancement. Other associated findings were also anlaysed. RESULTS: Two patients had normal MR features of the cavernous sinus. When compared with the contralateral normal cavernous sinus, the involved cavernous sinus was enlarged in six of the nine patients. The outer dural margin was convex and bulged laterally in 6 cases, flat in 2 cases, and concave in 1 case. Of the nine patients, five had iso-signal intensity and four had low signal intensity relative to gray matter on short TR/short TE. Three had isosignal intensity and 6 were not detectale on long TR/short and long TE pulse sequence. Contrast enhancement was seen in 8 cases ;7 cases showed homogeneous enhancement, 1 case heterogeneous enhancement. CONCLUSION: In the appropriate clinical setting of painful ophthalmoplegia, MR findings of cavernous sinus abnormality that consist of iso to low signal intensity on short TR/short TE images and isointense or undetectale mass on long TR/short TE or long TR/Iong TE images may suggest the dignosis of Tolosa-Hunt syndrome.

Syphilitic granulomatous pancreatitis is an extremely rare condition,and can occur in the generalized acquired syphilitic patient in tertiary or secondary phase. The most serious problem with granulomatous pancreatic lesion is clinical or radiological misdiagnosis as cancer. We experienced a case of syphilitic granulomatous pancreatitis arising in 54 year old female patient. She was treated for syphilis 20years ago. But she and her husband are still strong positive to VDRL and TPHA. On abdominal computed tomography and endoscopic pancreatico- duodenography, there was an obstructive mass of low density in the distal common bile duct or pancreatic head. Under the preoperative diagnosis of pancreatic head carcinoma, Whipple's operation was done. On gross examination, the pancreas was fibrotic, and the common bile duct was well preserved without tumor mass. Microscopically, numerous intralobular noncaseating epithelioid cell granulomas with multinucleated giant cells are identified. They surround thick-walled, small to medium sized arteries and involve vascular wall with luminal narrowing or obliteration, which are characteristic findings of the syphilitic granuloma. The remaining parenchyme shows fibrosis, acinar atrophy or destruction with dense infiltration of lymphohistiocytes, plasma cells with granuloma formation. Although the Warthin-Starry stain reveals no spirochetes, the serologic result and pathologic findings are compatible with syphilitic granulomatous pancreatitis.

Papillary and solid epithelial neoplasm is a rare pancreatic tumor of low-grade malignancy. We report a case of a 23 year old female having solid and papillary neoplasm of the pancreatic tail with mutiple omental and peritoneal metastases. Microscopically, the main tumor showed typical histologic findings including solid and papillary areas with cystic change. But the metastasizing nodules were largely solid and the tumor cells demonstrated increased nuclear pleomorphism, hyperchromasia and an increased mitotic rate. The tumor cells contained considerable amount of intracellular and extracellular eosinophilic inclusions which were ultrastructually zymogen-like granules. These inclusions were more frequently found in the metastatic nodules. By flow cytometric study, the tumor was hyperdiploid. The DNA index was not significant.

On video fluorescein angiogram, it is known that arm-to-retinal circulation(ART)influences retinal macrocirculation and arterio-venous passage time(AVP)influences microcirculation.In diabetic retinopathy(DR), midperiphery involved earlier than posterior pole.However, there has been no study on the circulation of the entire retinal circulation including the peripheral retina. The authors conducted a prospective study by performing fluorescein angiography on 19 controls and 19 DR patients in order to measure the ART, AVP and venous filling time(VFT). The VFT correspond to the circulation of the peripheral retina. In the DR group, the retina circulation time was compared with the existence of proliferative diabetic retinopathy(PDR), distribution of nonperfusion area and beading vessels. There was no significant difference between diabetic group and the control group in the ART.AVP was 1.8+/-0.7sec in the control group and 2.5+/0.7sec(p=0.04)in the DR group and venous filling time was 6.4+/-2.4sec and 8.9+/-1.5sec(p=0.006)respectively. Patients with PDR showed prolongation only in VFT compared to patients with non-proliferative diabetic retinopathy(NPDR). In addition, patients presenting with nonperfusion areas and beading of vessels showed longer prolongation of VFT than of AVP. In conclusion, the VFT is delayed in DR compared to control group and in PDR compared to NPDR. The VFT can be utilized as an indicator of DR to measure the retinal circulation including the peripheral retina.

We analyzed 13 cases of adult intussusceptions, which has been surgically treated, during the period from January 1987 to June 1997. There were 6 benign tumors, 2 malignant tumors and 5 others. The most common presenting symptom was abdominal pain. The types of intussusception were 3 jejuno- jejunal, 4 ileo-ileal, 1 ileocolic, 2 ileo-ileo-colic, and 1 colo-colic, intussusception of the vermiform appendix, and 1 combined type. In the pathlogic findings of the tumors, lipoma was the most common benign tumor and metastatic malignant melanoma was the most common malignant tumor. Other benign conditions were adhesion and granuloma due to tuberculosis. Surgical procedures were manual reduction, small bowel resection and anastomosis, a right hemicolectomy, a partial colectomy, and a polypectomy.

The signal intensity of paranasal sinus mucocele is highly variable, ranging from high to low on both T1 weighted and T2 weighted sequence, This variation is likely due to the combined effects of decreased free water concentration, cross-linking and polymerization of the macromolecular mucus glycoprotein, and increased viscosity. We have experienced three cases of the paranasal sinus mucocele with different signal intensity on Magnetic Resonance Imaging. We describe MR characteristics of the paranasal sinus mucocele and compare with MR characteristics for other paranasal sinus disease.
