The CT can image both bone and soft tissue structures of paranasal sinuses and face and so CT has added animportant new dimension to radiological evaluation of disease of paranasal sinuses and face. CT is more accuratemethod of staging of tumors and essential for therapeutic planning. The author studied 25 cases of proven tumorsof paranasal sinuses and face during the period from Oct. 1977 to Aug.1980 in Kyung Hee University Hospital. Theresult were as follows; 1. Among 14 females and 11 males, their age range was form 14 years to 65 year. 2. Thedistribution of tumors were mucocele, squamous cell carcinoma, metastatic carcinoma, meningioma, angiofibroma,Masson's hemangiosarcoma, fibrous dysplasia, neurogenic sarcoma, Schwannoma, hemangioma, epidermoid, transitionalcell carcinoma and unknown. 3. Determination of location and extent of mucocele was easily done by CT. Thus in allcases of esthmoid mucocele, chief complaint of exophthalmos could be easily explained by identification of itsextension into peripheral fat space of orbit. 4. It is our belief that CT was useful method to determine stagingof tumors of paranasal sinuses and was essential in choosing appropriate treatment modality. 5. The contrastenhancement is generally not helpful in pathologic diagnosis of tumors but intracranial extension of tumors areclearly defined by contrast enhancement.

Tinea barbae is one of the relatively rare chronic dermatophytosis of adult male, developing on the beard and moustache area of the face. We observed in a 50-year-old male patient who showed atypical clinical findings of tinea barbae. Initially, we impressed sycosis vulgaris, due to diffuse multiple pustular nodules with swelling on the beard area and both cheek of the face. We had treated him by antibiotics anri no improvement was noticed. On the 20th day from first visit, Trichophyton mentagrophytes was identified, and histopathologic exam revealed many spores and hyphae on the hair follicle. His skin lesions were almostly cleared after injestion of 5 months period of griseofulvin.

Aberrant left-sided pulmonary artery(pulmonary artery sling) is an uncommon anomaly, which may cause significant respiratory abnormality. We report a case of pulmonary artery sling which is combined with persistent left superior vena cava and dextrocardia. This case was identified by esophagogram and CT and confirmed by MRI and angiography. We consider that MRI is a valuable new method for the diagnosis of aberrant left-sided pulmonary artery.

Internal hernia is an unusual cause of the intestinal obstruction. The advances of CT make the diagnosis more easier than in the past. We report one case of internal hernia with herniation of the ileum into the lesser omenturn. The diagnosis could be made when abdominal radiographs showed fixed clustering of the small bowel loops in upper abdomen medial to the stomach. CT and ultrasound showed characteristic interposition of the ileum between the left hepatic lobe and the stomach.

The most common causes of conjugated hyperbilirubinemia after the first or second week of life are neonatal hepatitis and biliary atresia. Since these entities represent variable expressions of same pathologic process and have similar clinical, biochemical, and histologic features, differential diagnosis is extremely difficult. We prospectively studied 28 jaundiced infants by sonography and hepatobiliary scintigraphy. Final diagnoses included 12 biliary atresia and 16 neonatal hepatitis. Visualization of a normal-sized common bile duct or gallbladder was compatible with the diagnosis of neonatal hepatitis. Non-visualized or atrophic gallbladder no sonography coupled with non-visualization of bowel activity on scintigraphy was highly suggestive of biliary atresia. We believe that sonography plays valuable role in the initial evaluation of the infants with persistent neonatal jaundice. The combined use of sonography and hepatobiliary scintigraphy provides the most valuable in formation in suspected biliary atresia for prompt surgical treatment.

We report a case of giant M llerian duct cyst in a 6 month-old-boy with urinary tract infection. A mass displacing the bladder and prostatic urethra anteriorly was found on the voiding cystourethrogram, and it was a oval shaped retrovesical anechoic cyst on the abdominal ultrasonogram. On MRi, it was a tear-drop shaped cyst of isosignal intensity with a projection toward the prostatic urethra and located in the midline of vesicorectal space. Grossly, the cyst had communication with prostatic urethra and both vas deferenses were drained to the cyst. Pathologically it was confirmed as a M~'llerrian duct cyst lined with squamous epithelium.

The utilization of CT-guided fine needle aspiration biopsy of bone has been the subject of considerable interest, since the introduction of the CT scanning. The CT-guided needle biopsy of 11 consecutive patients with avariety of "Etiology Unknown Spinal Disorders" resulted in a 100% yield of positive tissue diagnosis without significant complicaitons. The main advantage of CT guidance is the continuous direct observation of the needletip position in relation to the target volume, the more precise sampling from smaller and deeper lesion is another advantage. We are confident that localization of pathology by CT is the most accurate method for perform ingbiopses, and thus replaces the conventional ways of approaches and this could be utilized on the other organbiopsy in the future.
