In a study of intracranial metastases, 46 cases having satisfactory clinical, oprative and histological proofs were analyzed by computerized tomography at Presbyterian Medical Center from May, 1982 to February, 1986. The results were as follows : 1. The male to female ratio intracranial metastases were 67:33. the 5th decade group (34.8%) was the most prevalent age group, followed by the 6th decade (21.7%) and 7th decade(21.7%). 2. The number of lesions was found to be : single -25 cases(54.3%) ; multiple-21 cases(45.7%). 3. The source of intracranial metastases found to be : lung 15 cases(32.6%) : unknown 12 cases (26.0%) ; chorioca 3 cases (6.5%) : liver 3 cases(6.5%) : stomach 2 cases(4.3%) : parotid , breast, kidney, prostate, melanoma, rectal ca, rhabdomyosarcoma, nasal ca, lymphoma, testicular ca, cervix, each 1 cases(2.2%). 4.The location of the intracranical metastases were as follows : Cerebral hemisphere 37.7% in parietal region Cerebral hemisphere 15.9% in frontal r gion Cerebral hemisphere 13.4% inoccopital region Cerebral hemisphere 10.5% in temporal region Cerebral hemisphere 3.2% Cerebellopontine angle 3.2% Intraventricular 4.8% Meninges 4.8% Skull vault 6.5% 5. Peritumor edema was found to be : Grade-II17 cases(37.05) : Grade III-14 cases(30.45) : GRadeI-8cases(17045) : Grade0-7 cases(15.2%) in that order. 6. The chief complains of intracranial metastases on admisson , were as follows : Headache 30 cases(65.2%) : Vomiting 11 cases(23.95) : deteriorated mental state 10 cases state (21.7%) : Hemiplegia 7 cases(15.2%) : visual disturbance 6 cases(13.0%) : hemiparesis 4 cases(8.7%) : seizure 4 cases (8.7%) : other symptoms were less frequent. 7. On pre-contrast scan, hyperdense lesions were present in 18 cases (69.1%) : hypodense lesions in 15 cases(32.65) mixed density in 8 cases (17.4%) : isodensity was present in 5 cases(10.9%). On-post-contrast scan, ring enhancement was seen in 19 cases (41.3%) : nodular enhancement in 17 cases (375) ; mixed ring-nodular enhancement in 8 cases(17.4%) : only hypodense 2 cases(4.3%)
