It is well established that the computed tomography (CT) is an essential part not only in screening primary brain tumors, but also in staging known malignancy. This paper reports various CT findings demonstrated in 12 cases of choriocacinoma with brain metastasis. The CT findings such as the number, location and density of the metastatic lesions, the degree of brain edema, mass effect and effect of contrast enhancement are reviewed as well as the episode of stroke syndrome and survival duration after neurologic symptom attacks. The results were as follows: 1. Ten of these cases showed solitary metastatic lesion and remaining 2 cases were multiple lesion. 2. One was isodense density and the others were hemorrhagic increased density by CT. 3. All of these showed mass effect to the surrounding structures along with moderate to marked brain edema. 4. The position of the metastatic lesion were located at the supratentorially in all cases. Most of them were at the unilateral frontal or parietal area or both of them. One which noted multiple metastatic foci showed at the bilateral occipital regions. 5. Nine cases showed ring enhancement after contrast infusion, One which noted isodense density on the noninfusion scan showed also ring enhancement after contrast infusion. 6. Nine cases showed positive stroke syndrome. One of them was performed emergency craniotomy. The remaining'3 cases noted progressive neurologic symptoms. 7. Two cases were noted only brain metastasis but the others also had various degree of pulmonary metastasis and 2 of latter had hepatic metastasis, too. 8. Most of the cases were treated with CHAMOCA regimen, and one of them was taken whole brain irradiation (3000 rads/2 weeks). Another one case revealed marked regression of not only metastatic brain lesion but the pulmonary lesion after the 8th course of CHAMOCA regimen and still alive for over 460 days.
