Thirty-five cerebello-pontine angle lesions were diagnosed with simple skull X-ray, CT, and angiography atSeoul National University Hospital from Sept. 1978 through Aug. 1982. The radiographic findings were analysed withemphasis on the differential points of CT among the major three cerebello-pontine angle tumors; acousticneurinoma, meningioma and epidermoid. The results are as follows; 1. Among the 35 cases of cerebello-pontine anglelesions, 19 cases were acoustic neurinoma. 4 cases miningioma, 4 cases epidermoid, 2 cases metastasis, 1 caseschoroid plexus papilloma, 1 case arteriovenous malformation, and 3 cases intra-axial posterior fossa tumors. 2.The characteristic radiographic findings of acoustic neurinoma were windening of internal auditory canal, petrousbone erosion, posterior extension of tumor at the level of internal autidory canal, hypo or isodense mass onpre-contrast CT with high enhancement after intravenous contrast infusion, and cystic change within the mass. 3.Meningioma shows anterior extenstion of the lesion at the level of internal auditory canal, broad base and obtuseangle sign of the lesion with petrous bone, hyperdense mass on precontrast CT. with highly homogeneous enhancementafter intravenous contrast infusion. 4. Epidermoid characteristically shows hypodense mass on precontrast CT withno change after intravenous contrast infusion. 5. The differential points of the major 3 cerebello-pontine tumorswere bone change, mass location, attenuation , degree of attachment to petrous bone, and cystic change.

Phakomatosis pigmentovascularis is characterized by the coexistence of pigmentary and vascular nevi, which are occasionally associated with systemic organ involvement. We report a 12-year-old male, who showed bilateral nevus of Ota on the forehead, periorbital area, sclera and soft palate, nevus of Ito on the scapular area, mongolian spot on the sacral area and widespread nevus flammeus. He was also associated with congenital temporal alopecia on the lower portion of left temporal region since birth.

Myocardial ischemia occurs when myocardial oxygen availability is inadequate to meet metabolic requirements. The common cause of myocardial ischemia is atherosclerotic epicardial coronary arteries. Isoflurane is a potent small vessel-type coronary vasodilator and has the potential for causing regional myocardial ischemia in patients with coronary disease, but it's still controversial. We experienced a case of transient myocardial ischemia during general anesthesia with isoflurane. The patient was a 51 year- old male who underwent a direct clipping of an anterior communicating artery aneurysm. There was no specific abnormality on preoperative laboratory tests except for mild mitral valve regurgitation on the cardiac echocardiogram. He had once experienced several minutes of sudden severe chest tightness just 3 months before admission, but it had subsided without any specific treatment. One hour after beginning of operation, abnormal EKG changes such as ST-T elevation, QRS widening, VPC, ventricular tachytcardia and ST-T depression appeared and then normalized within 2 minutes with stopping isoflurane and using isosorbide dinitrate. He discharged 12 days later without complications. After discharge, Tread-mill test, SPECT and 2D echocardiogram were performed but there was no any evidence of coronary artery disease.
