The primary malignant melanoma arising in the leptomeninges of the central nervous system is extremely rare. We report a case of malignant melanoma, apparently thought to be originated from leptomeninges, with diffuse neoplastic process widely spreaded over the leptomeninges of 42 years old man, who had suffered severe headache, nausea and left hemiparesis. This patient is free of the symptoms for six months after operation. The literature on this subject is briefly reviewed.

Meningioma is generally regarded as benign and extracranial metastasis of intracranial meningioma is rare. About 60 cases of distant metastasis of meningioma have now been reported. Angioblastic meningioma, although a rare type, shows rapid growth and sarcomatous change frequently, and has higher incidence of metastasis than other types of meningioma. The authors report a case of malignant angioblastic meningioma arisen in left olfactory groove with multiple metastasis to skeletal system. The available literature regarding these tumors is reviewed.

Existing methods of stereoacuity testing need specific glasses or optical device for use. We have designed a new stereoacuity test for the digitalized, random-dot stereogram and researched its clinical usefulness. A digitalized, random-dot, stereoacuity test card was created with a computer program that used a preferred symbol and the designed system was tested along with the Randot preschool stereoacuity, Titmus-fly and Lang tests to compare their sensitivity and specificity. The mean success rate of the digitalized, random-dot test was 98.2%, while the rates of the Randot preschool stereoacuity, Titmus-fly and Lang tests were 89.3%, 74.2% and 86.1%, respectively. Sensitivity and specificity of the new test were 100% and 95.3%, respectively, which were not that different from those of the Randot preschool stereoacuity, Titmus-fly and Lang tests. We found that the digitalized, random-dot, stereoacuity test has a high success rate and can be appropriately used in medical examinations and follow-up tests for strabismus patients.

Endoscopic suspension of bladder neck by Stamey's procedure is a successful technique of correcting female stress urinary incontinence. We treated 27 patients complaining of urinary incontinence with Stamey operation from February, 1988 to March, 1994. The results was as follows l. Patients was distributed in age from 31 to 63 (mean; 48.8) years. All patients except one were multiparous, average 3.6(2-6)times of deliveries 2. Severities of incontinence were Grade I in 2 patients, Grade II in 20, Grade III in 5. 3. On preoperative lateral cystourethrogram, bladder base was descended about 1.1+/-0.57cm in resting, 2.63+/-1.24cm in straining from SCIPP(Sacrococcygeal-inferior point of pubic bone) line. Preoperative average PUVA(Posterior urethrovesical angle) was 142.2+/-53.27 degree, and average functional urethral length was 2.84+/-l.36cm. 4. Postoperative times of catheterization was 5.8 days, the amount of residual urine was lO5+/-10.3cc after removal of catheter. 5. Incontinence was completely disappeared in 24 patients(88.9%), but 3 patients were recurred due to break of suture material.

PURPOSE: To compare foveal shapes in Koreans according to age and gender using spectral domain optical coherence tomography (SD-OCT). METHODS: This study included 230 eyes of 115 healthy adults. The subjects were divided into three groups: group 1 (20-39 years of age), group 2 (40-59 years of age) and group 3 (60-79 years of age). Using spectralis OCT, we measured central foveal thickness (CFT), regional maximal retinal thickness (MRT), pit diameter and pit depth and compared the differences between the groups. RESULTS: The MRT of the superior, inferior and nasal sides in group 1 was higher than in groups 2 and 3 (p < 0.05). No significant difference was observed in the MRT of the temporal side. Regarding differences based on age, no significant differences in CFT, pit diameter and pit depth were observed. Regarding differences in gender, the temporal regional MRT of males in group 3 was significantly lower than in group 1 and the pit depth of males in group 1 was significantly higher than in groups 2 and 3. Therefore, differences were observed according to gender. CONCLUSIONS: In the present study, differences in foveal shape were found according to age and gender which should be considered when foveal diseases are evaluated.

Neurilemmoma is well-encapsulated tumor of Schwann cell origin. The majority arise in peripheral nerve or cranial nerve, and rare in retroperitoneum. Although it is incidentally detected by the advances in diagnostic procedures, especially in ultrasound and computed tomography, it is confirmed by pathologic findings. The treatment is surgical excision. We report a case of retroperitoneal neurilemmoma arising from adjacent to adrenal gland, in 45 years old female.
