Most subdural hematoma with significantly differed attenuation from that of adjacent brain tissue can beaccurately diagnosed by CT. Difficulty arises when the hematoma is isodense that is exhibited similar attenuationto that of brain. Unilateral isodense subdural hematoma can be identified by indirect sign such as mass effect.Occasionally, the use of intravenous contrast material to aid in identifying isodense subdural hematomas has metwith variable success. Moreover, bilateral isodense subdural hematoma may be more difficult. We therfore considerdit of interest to evalute the diagnostic efficiency of CT in isodense subdural hematomas. We have analysed 13cases surgically provened cases of isodense subdural hematoma examined at Korea General Hospital from Oct. 1981 toApril. 1982. The resuls were as follows; 1. One hundred twenty seven cases of subdural hematomas were studied byCT, 13 cases (19.2%) of which were isodense. 2. The age distribution was from 29 years to 69 years and mean agewas 52 years. The sex ratio was 11 male to 2 female. 3. Seven(53.8%) of 13 cases has a history of head trauma. 4.The time interval which subdural hematoma became isodense was from 1 week to 4 months and peak time interval wasfrom 1 week to 3 weeks. 5. The precontrast CT of isodense subdural hematoma appeared shifting of midlinestructure, compression and deformity of the ventricles in all 13 cases, effacement of cerebral sulci in 10 cases(76.9%) and dilatation of contralateral ventricles in 4 cases (30.8%). 6. The postcontrast CT scan demonstratedenhancement of the medial margin of the lesion in 4(30.8%) of 13 cases and displacement of cortical vein away fromthe inner table of the skull in 3 (23.1%) of 13 cases. 7. Bilateral isodense subdural hematomas were 2 (15.4%) of13 cases.

Paranasal sinus CT is known as the most effective imaging modality in the evaluation of inflammatory sinonasal diseases and can depict the distribution, causative lesions obstructing main drainge route, and associated findings. Recently, functional endoscopic sinus surgery has been widely used for the evaluation and treatment. Before operation, PNS CT has been routinely used to evaluate the paranasal sinuses and mucociliary drainage route. The authors analyzed the PNS CT findings of 3156 cases in 1578 patients with chronic sinusitis symptoms. Sinonasal inflammatory diseases were categorized into 5 patterns according to the obstruction sites. They were 1) infundibular (10%, 316/3156), 2) ostimeatal unit (41%, 1294/3156), 3) sphenoethmoidal recess (12%, 379/3156), 4) sinonasal polyposis (30%, 946/3156) , and 5) unclassifiable (6%, 190/3156) patterns. The main causes for infundibular obstruction in order of frequency were inflammatory mucosa, enlarged ethmoidal bulla and Haller's cell. With respect to the middle meatus obstruction, is main causes in the order of frequency were polypoid lesion, inflammatory mucosa and medially deviated uncinate process. In particular, sinonasal polyposis showed one or more of the characteristic associated findings of infundibular enlargement, air-fluid level, ethmoidal sinus was bulging and bony deossification or sclerosis as well as sinonasal polypoid change. In conclusion, the inflammatory sinonasal diseases were classified into five patterns, and the causative lesions or anatomic variations were efficiently detected by the PNS CT. Furthermore, it could provide a guidance for proper management of the sinusitis including functional endoscopic sinus surgery.

Calcific tendinitis of the shoulder joint is common disease causing acute pain, mainly involving the supraspinatus or infraspinatus muscle, and less frequently the teres minor or subscapularis muscle. This study reports on the satisfactory arthroscopic removal of calcium deposits as well as infraspinatus and supraspinatus muscle repair without relapse via minimal incision using suture anchors. This was a case of atypically extensive calcific tendinitis involving the infraspinatus muscle, with a bursal side partial rupture of the supraspinatus muscle in a 61-year-old female whose chief complaint was chronic pain of the right shoulder exacerbated by limited movement.

The Farnsworth-Munsell 100 Hue Test is very useful clinical color discrimination test for detecting color deficient person in quantitative and qualitative diagnosis. In this study 45 subjects were examined by the F-M Test and of these 22 were diagnosed as normal and 23 as color anomalous. The 23 anomalous persons were composed of 6 deutans, 9 protans and 8 unclassified red-green defects. These 23 color anomalous subjects were examined by the three kinds of pseudoisochromatic plates), Ishihara (15 plates), Dvorine (15 plates) and Ao H-R-R (20 plates), and their results were compared with the results of the Farnsworth-Munsell test.
