Pinealoma is an uncommon from of intracranial neoplasm, but is relatively common in oriental We have usually used positive contrast ventriculography for diagnosis of the tumor rather than angiography. However, verbebral angiography has become increasing precise, accurate and detailed. For the evaluation of diagnostic value and angiographic characteristics, we reviewed the radiologic feature of 10 cases of pinealoma which were diagnosed at Severance Hospital, Yonsei University College of Medicine from Jan. 1970 to Sept. 1977. Result as follow: 1. Peak age incidence is 2nd decade and the male: female sex ratio is 9 : 1 reflecting the usual male predominance in pinealoma. 2. Major symtomatic manifestrations are headache (10/10), nausea and vomitting (8/10) and visual distrubance (8/10). Eye signs are main feature. Of 10 cases, 8 cases showed Parinaud syndrome, 7 cases papilledema and 3 cases disturbance of light reflex. Two cases showed cerebellar sign and one case showed precoci us puberty. 3. In plain skull x-ray, 8 cases showed findings of increased ICP and four pincal calcification. 4. Radionucleide brain scan is little helpful. Only one in 7 cans showed abnormal finding. 5. Ventriculography using positive contrast was performed in 8 patients. 6 cases showed classic filling defect in posterior part of 3rd ventricle, 5 cases foward and downward displacement of the Aqueduct of Sylvius which become narrowed and obstructed and in all cases hydrocephalus finding. 6. The change of posterior choroidal artery measured by Pachtman's maneuver in 3 cases is as follow. One showed posterior displacement of posterior choroidal artery with seperation of interchoroidal artery. The other showed no specific change. The remained one showed approximation of interchoroidal distance without descent. The change of vein is also demomstrated. Elevation and posterior displacement of internal cerebral vein is observed in 3 cases out of 9. Posterior and superior displacement of vein of Galen is noted in 3 cases out of 6. In 6 cases, 2 cases showed equivocal change of basal vein. Pineal vein changes were observed in 2 cases which showed open claw of a crab figure.
