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.

CT was done 81 times on 63 proven malignant maxillary sinus tumors for 3 years from Feb.1979 to May 1982 atSeoul National University Hospital. Pre-treatment CT were 54 and post-treatment CT were 31 on 28 patient. Theresult were as follows; 1. The most frequent histopathologic diagnosis was 44 cases (69.8%) of squamous cellcarcinoma. Others were 5 cases (7.9%) of adenoid cystic carcinoma, 3 cases (4.8%) of olfactory neuroblastoma, 3cases (4.8%) of malignant lymphoma, 2 cases (3.2%) of melanoma, 2 cases (3.2%) of malignant fibrous histiocytoma,a rhabdomyosarcoma, a basal cell carcioma, a fibrosarcoma and a metastatic carcinoma from thyroid follicular adenocarcinoma. 2. The CT findings in 54 untreated malignant maxillary sinus tumors were sinus opacification, softtissue mass, and bone destruction in all cases. Other findings were fat plane obliteration (70%),osteosclerosis(59%), bone erosion and displacement (46%), low densities within soft tissue mass (27%), and airdensitis wiithin soft soft tissue mass (27%), and air densities within soft tissue mass(13%). 3. The value of pre-treatment CT in malignant maxillary sinus tumors were outlining the disease process especially soft tissuesuch as orbit, infratemporal fossa, pterygopalatine fossa, nasopharynx, pterygoid fossa and intracranialextension, and CT is the choice of diagnostic modality to determine the prognosis and the therapeutic planning insurgery and/or radiotherapy. 4. Post-treatment CT is also helpful to evalute the change in tumor size andpost-treatment complication.

Authors performed angio-CT(portal &/or arterial CT) in 35 patients with various hepatic masses. We obtained portal CT in 32 and arterial CT in 13 patients. The contrast material was injected into superior mesenteric artery for portal CT and into hepatic artery for arterial CT after transfemoral cathetrization of these arteries. We concluded that portal CT was superior to other imaging modalities highly sensitive in detecting hepatic masses, especially, early hepatocellular carcinomas, daughter nodules, and subclinical metastatic hepatic malignancy, With this method, detection rate of early hepatocelluar carcinomas improved 62% in number of patients and 90% in number of masses. Detection rate of subclinical hepatic metastases improve 60% each in number of patients and in number of masses. It was also useful for the detection of portal vein invasion. Arterial CT was useful in differential of masses and in defining the characteristics of entire or part of the masses because this method revealed hemodynamic patterns more definitely.
