Subretinal neovascular membrane in the macula is a major cause of central visual loss. We reviewed the clinical records, fundus photography, fluorescein angiography of the 172 eyes of 166 patients in order to disclose the causes and clinical characteristics of subretinal neovascular membrane and performed argon and krypton photocoagulation in 22 patients. The common causes of subretinal neovascular membrane are idiopathic neovascular membrane, myopic and senile macular degeneration in order(27.1, 26.5, 22.3% aa). There was no significant difference in changes of visual acuity and extent of subretinal neovascular membrane between treatment and non-treatment groups.

Accurate preoperative CT staging of renal tumor affects the therapeutic approach and aids the urologist in planning the appropriate procedure. CT staging were compared in 33 patients with pathologically confirmed stage of renal tumor. The overall accuracy of CT staging in renal cell carcinoma is 87.0%. The overall accuracy of CT staging in renal pelvis tumor is 80.0%. The major role of CT was in the evaluation of renal capsule, perirenal fat, Gerota's fascia, renal vein, inferior vena cava and lymph node for invasion. We conclude that at the present time CT is the optimal technique to stage renal tumor.

Two cases of association of brain tumor and intracranial aneurysms are reported. One case is association of pituitary adenoma with anterior communicating artery aneurysm. The other is association of acoustic neurinoma with multiple aneurysms and it is exceedingly rare reviewing the available literature. Various pathogenesis for association of brain tumor with cerebral aneurysm have been postulated.

Defects in the dura mater can be result from craniocerebral trauma, neoplastic or inflammatory destruction surgical removal and congenital absence. Materials used for closure of dural defects were variable. Of these, autogenous fascia lata have been used for a long time. It seems interesting to study the histologic fate of the autogenous grafted fascia lata in the dural defects. After autogenous fascia lata graft to dural defect in 18 rabbits, the histologic fate of the autogenous grafted fascia lata was observed microscopically. The results are as follows: 1) The adhesions among the grafted fascia lata, arachnoid, pia mater and brain cortex were usually mild. This result may be due to either short period of observation or autogenous substitutional material. 2) The grafted autogenous fascia lata was revealed minimal inflammatory response and was ultimately reabsorbed. 3) The grafted autogenous fascia lata was replaced by granulation tissue and fibroblast originated from the host mesenchymal tissue.

Craniopharyngiomas are usually considered to arise from the pituitary stalk and upper aspect of the pituitary gland. However, they very rarely develop from the floor of the third ventricle or the lamina terminalis, and are intrinsically confined to the third ventricle ; about 40 cases have been reported in the literatures. We have recently experienced a case of intrinsic intraventricular craniopharyngioma with the density a little higher than cerebrospinal fluid on the brain CT.

Topographic electroencephalographic study(CME) is a newly developed method using a microcomputer system that displays the scalp topograph as the square roots of the average power spectra over each EEG frequency band on a color television screen. CME were applied to thirty patients, Fifteen patients out of them with focal neurologic deficit were analysed about CT scan and conventional EEG. The results of the study were as follows : 1) Comparing the results of CME and conventional EEG reading, CME revealed to be slightly more sensitive in detecting asymmetrical depression of background activity than the conventional reading of the EEG. 2) Topograph EEG study was more accurate than conventional EEG in lateralization of the lesion. 3) CME is very useful in topographic and objective diagnosis of functional lesion, although the source of the data is the same as that from the conventional EEG.

Software modules for interactive display, manipulation and retrieval of medical images have been designed for a Picture Archiving and Communications System (PACS). The target of these modules is not for a high-end diagnostic workstation for radiologists, but for a PC-based low cost clinical workstation for a referring physician. This software is constructed based on a concept of an object-oriented language which is designed to be modular and expandable. It consists of several functional modules: (a) a communication module for image retrieval, (b) a standard module for the interpretation of the DICOM images, (c) a user interface module for the non-computer oriented clinicians and (d) a tool module for viewing and manipulating images as well as editing the annotation.

Intracranial arachnoid cysts are uncommon congenital lesions of considerable interest and importance, the origins and exact nature of which remain uncertain. They account for about 1% of all intracranial space-occupying lesions4). Its predilection sites are in the sylvian fissure, the interhemispheral fissure, the cerebral convexity, the base of the brain, and over the midline of the cerebellum in the posterior fossa6)11). We are reporting a case of arachnoid cyst, developed in the left sylvian fissure in a ten years old male patient.
