Two cases of intracranial venous and sinus thrombosis without demonstrable causative factor in adult male were reported.

Case 1,38 years old male had sudden loss of consciousness with generalized tonic convulsion, and then complained of headache and motor weak-ness of right limbs. Blood examination and other routine examination revealed no abnormal datas. Examination of the CSF showed elevated protein and increased cell count in mild degree. Carotid angiography gave slowing of the circulation, cork-screw like appearance to the venules, occlusion of the superior sagittal sinus and bilateral tributary veins, also drainage to the deep or basal venous channels as well. Craniotomy was performed and thrombosed cortical vein was examined micro-scopically. The wall of vein was thined and the lumen contained partly organized thrombus which were mainly formed by thrombocytes. Any in-flammatory cells were found in venous wall and its lumen or subarachnoid space.

Case 2,23 years old male suffered from severe headache with nausea and vomiting for several weeks. Neurological examination revealed no ab-normalities except moderate papilledema. Exami-nation of the CSF revealed elevation of pressure and protein, but cell count was remained within normal range. Carotid angiography showed oc-clusion of superior sagittal sinus and bilateral tributary veins the same as shown case 1. Micro-scopical findings of the thrombosed cortical vein taken by craniotomy were also similar to case 1.

From these pathological findings of the affected cortical vein were dinied thrombophlebitis but suggested phlebothrombosis-so-called idiopathic intracranial venous and sinus thrombosis of un-known origin.
