We report a case of pulmonary infarction probably related with Henoch-Schönlein purpura, which presented with purpura on both lower extremities in a 27-year-old woman. The purpura had developed 4 days previously and it had no itching or tend'erness. She complained of mild fatigue, chest tightness, but no dyspnea or hemoptysis. On routine examination, chest radiography showed a poorly defined nodular opacity on the left lung field, and it was diagnosed by a follow up chest CT as a pulmonary infarction secondary to pulmonary vasculitis.

The lesions of central nervous system in tuberous sclerosis often calcify, especially those present in the perivascular region, allowing the computed tomography to make early and definite diagnosis, even when patients intelligence was normal, seizures were absent, or clinical findings were not specific, We report three cases of tuberous sclerosis, which showed pathognomic subependymal paraventricular calcification in brain CT.

Trichomoniasis, a common and sometimes distressing condition in women, is caused by infection of the genitourinary tract by the pathogenic protozoan Trichomonris aginalis(T. vaginalis). Men may also be infected, although frequently without any symptoms, and most cases of trichomoniasis are sexually transmitted. The best evidence for an etiologic role for T. vaginalis is in nongonococcal urethritis(NGU). In epidemiologic studies, T,ginalis has been isolated from 1 to 68 percent in men with NGU. The nurnber of NGU is increasing rapidly than gonorrhea in deeloped nations, and in some developing countries, especially in Korea, In view of the difficulties in findng trichomonads by direct microsco by in men, urine culture and serodiagnosis plays an important role in the diagnostic work. Urine culture, indirect fluorescent antibody test(IFAT) and enzyme-linked immunosorbent assay (ELISA) were used to elecect T.vaginalis in 221 patients with male NGU. These patients visited the VD Clinic of ChoongKu Public Health Center in Seoul from May to August, 1989 and from March, 1990 to December, 1991. The results obtained were as follows.: 1. T. vaginalis was grown from only one of the 221 samples on TPS-1 meida. 2. In 208 NGU patients, there were 10(4.8%) positive reactions on IgG antibody in IFAT. 3. In 208 NGU patient, there were 14(6.7%) positive reactions to IgG antibody in ELISA. 4. No statistical significant correlation was found between then sults of IFAT and ELISA in individual patients. In conclusion, 1. Male trichomoniasis in patients with NGU was detected at a, significantly low rate. Due to the small number of patients in the test, further epidemiologic stidies of trichomoniasis in male NGU patient are necessary. 2. Serologic studies (IFAT and ELISA) have detected sorre trichomoniasis in male patients with NGU. These tests seem to be helpful in the diagnosis of male t-ichomoniasis.

Fibrous dysplasia in the orbit and cranial base may involve the optic canal. Although fibrous dysplasia is benign, it may produce a mass effect along the course of the optic nerve which can then induce visual disturbance as well as contour deformities of the skull and facial bone. The treatment of fibrous dysplasia in the orbit and cranial base is to resect the lesion as much as possible and then reconstruct immediately. As well, if there is any evidence of optic canal involvement and disease progression, the treatment of fibrous dysplasia may include optic nerve decompression. It is generally understood that some patients experience improvement of visual function after optic nerve decompression. We performed radical excision and reconstruction by means of autogenous calvarial bone graft and methylmethacrylate in 7 cases. The autogenous calvarial bone was used to reconstruct the orbit. The methylmethacrylate was used to reconstruct bony defect in the temporal area. The orbit was reconstruced into one block which was made of autogenous calvarial bone with a microplate and screw. This method is superior compared to the previous multifragment wiring method with regard to stability, operation time, and appearance. The patients in our series showed satisfactory appearance. In 6 cases, we performed optic nerve decompression. Therapeutic optic nerve decompression was done in 3 cases and prophylatic optic nerve decompression was done in the others. Following therapeutic optic nerve decompression, visual acuity was improved in 2 cases while the others showed a decrease in visual acuity. There was no change of visual acuity and visual field in 1 case after prophylactic optic nerve decompression. However, the others showed decrements in visual acuity or visual field. Therefore, we believe that more attention should be paid during optic nerve decompression procedure and strict indications to that procedure should be applied.

PURPOSE: To characterize the MRI appearance of the peripherally located schwannoma as compared with pathologic findings. MATERIALS AND METHODS: 11 cases of 13 lesions of the schwannoma confirmed by pathology were analyzed, retrospectively. T11 T2 and Gadolinium-enhanced T1 weighted sagittal and axial images were obtained. The signal intensity, contour of lesion, and relationship with surrounding tissue were analyzed. All cases were correlated with MRI and pathologic findings. RESULTS: In 9 out of the 11 cases, schwannoma was connected to the main nerve trunk. Among them, tumors were located centrally in 6 cases and eccentrically in 3 cases. MR findings of schwannoma were iso signal intensity on T1WI(8 cases) with muscle intensity, high signal intensity on T2WI(all cases), strong heterogenous enhancement in all cases. 8 cases showing heterogenous appearance on T2WI, showed mixture of Antoni-A and B area and multifocal hemorrhage. Central low and peripheral high signal intensity on T2Wl(Target sign) was mainly high cellular component in the central portion and diffuse myxoid degeneration at the periphery, pathologically. Reversed target appea.rance(central high, peripheral low on T2WI) revealed central cystic degeneration with low cellular component and hemorrhage in the central portion, and high cellular component at the periphery. Linear band-like low signal intensity on T2WI, suggesting capsule of the schwannoma, was not the true capsule proven by pathology. Thin true capsule was not visualized on T2WI. CONCLUSION: MR appearance of schwannoma was non-specific. The signal intensity on T2 weighted MR imaging was determined by the presence of multifocal hemorrhage, focal cystic and myxoid degeneration, admixture of Antoni-A and B area.

From September 1992 to April 1994, we reviewed 7 patients after arthroscopic surgery for anterior impingement in the ankle, who complained ankle pain and limitation of motion. All patients were mem and main symptoms were severe pain at full dorsiflexion of ankle and limitation of motion. Bony spur was located on the anterior aspect of tibia, and it was possible to resect the tibial bony spur arthroscopically without distraction devices. Mean operation time was 55 minutes. Pain, swelling and limitation of motion were much improved. There was no postoperative complication. Arthroscopic resection of the anterior tibial bony spur is an effective treatment for anterior impingement in the ankle.
