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.

Trichofolliculoma is a benign tumor of hair follicle and is intermediate in differentiation between a hair nevus and a trichoepithelioma. It is a rare dermatosis first described by Fessler in 1924. Clinically, asymptomatic 4-5 mm sized solitary tumor usually occurs on the scalp, head and neck in the adultnood, This tumor may be clinically suspected if occurs as a small domeshaped nodule with a central umbilication showing small wisps fimmature hairs. Microscopically, the turnor shows one or several keratinfilled cysts in the dermis which are surrounded by spuamous epithelium, and contain horny meterial and birefringent fragments af hair shaft. These are primary hair follicles. And there are small secondary hair follicles which appear to radiation from the pimary hair follicles and have fine hair. The surrounding squarnous epithelium of primary follicles form epithelial strands, and interconnection the secondary hair follicles. We presented here a case of trichofolliculoma with typical clinical and histopthological findings in a 41 year-old male patient.

Bizarre parosteal osteochondromatous proliferation was first described in 1983, when Nora and his collegues reported 35 examples of a proliferative lesion involving bones of the hands and the feet. In 1993, Meneses reported 65 cases of this condition. A fourth of all the reported cases involved the long bones. It is important to identify the clinical, roentgenographic, and histologic characteristic to seperate it from other entities because it is a benign lesion with atypical microscopic features with a tendency to recur. Roentgenograms show a calcific mass attached to the underlying cortex having a broad base. Histologically, the lesion exhibites proliferative activity, irregular bony cartilaginous interfaces, and enlarged, bizarre, and binucleated chondrocytes. We reviewed the bone tumors, diagnosed in the KyungHee University Hospital, dated from 1984 to 1994. Five cases were revised to Nora's lesion, all of which were previously diagnosed as osteochondroma. The ages of the patients ranged from 12 to 57 years (median, 19 years), and all of them were males. Two cases involved the bones of hands and feet (metacarpal and talus), and 3 cases involved the long bones (humerus, fibula, and ulna). One lesion involving the humerus has a recurrence. No metastasis had been reported.

Although obstruction of the carotid artery after head trauma or non-penetrating injuries of the neck had been well known, reports of occlusion of middle cerebral artery following closed head trauma are rare. Up to now Jacque, et al, have found only 22 cases of posttraumatic middle cerebral artery occlusion including their own one case in the world literatures since DeVeer and Browder reported the first case in 1942. We report a case of posttraumatic middle cerebral artery occlusion. The patient developed right hemiplegia, aphasia and mental confusion 2 days following closed head trauma. Left cerotid angiograms revealed complete occlusion of the horizontal portion of the left middle cerebral artery distal to the origin of the lenticulostriate branches. Previously reported cases are review and possible pathophysiological mechanisms discussed.
