The authors experienced two cases of cervical epidural AVM resembling that of tumor. It is the purpose of this report to point out by means of two cases the problem involved in establishing the diagnosis. To our knowledge, our two cases of cervical epidural AVM is the first report in Korea.

Recently, transsphenoidal approach is regarded as the principal method for the resection of pituitary tumor. The sublabial transseptal transsphenoidal hypophysectomy is a classical one, but it has certain limitations and postoperative problems. So various modifications of transsphenoidal hypophysectomy have been proposed. The columellar flap is one of such modified approaches.

OBJECTIVE: To investigate the frequency, type and severity of cardiac abnormalities in the patients with ankylosing spondylitis and undifferentiated spondyloarthopathy. METHODS: A history, clinical examination, standard 12 lead electrocardiography, two dimensional, M mode, and Doppler echocardiographies were performed on 19 patients with ankylosing spondylitis, 15 patients with undifferentiated spondyloarthropathy and 21 normal controls. RESULTS: 1) Cardiac abnormalities were detected in 8 patients(42.1%) with ankylosing spondylitis. 2) Cardiac abnormalities were detected in 8 patients(53.3%) with undifferentiated spondyloarthropathy including 2 patients with aortic valve abnormalities(mild aortic insufficiency, aortic valve thickening. 3) Cardiac abnormalities were detected in one (4. 8%) among normal controls (mild tricuspid regurgitation). 4) There were sinus bradycardias on electrocardiography in 2 patients among patients witn anl;ylosing spond!litis and in 1 patient among undifferentiated spondyloarthropathy. But there was no conduction disturbance in both groups. 5) The frequency of cardiac abnormality was higher in patients with ankylosing spondylitis and undifferentiated spondyloarthropathy than in normal controls. 6) The mean age, mean disease duration, presence of uveitis, peripheral arthritis, HLA-B27, enthesopathy, Schober test and chest expansion in the patients with ankylosing spondylitis and undifferentiated spondyloarthropathy with cardiac abnormalities were not different from those in the patients without cardiac abnormalities. CONCLUSION: The frequency of cardiac abnormality was higher in patients with ankylosing spondylitis and undifferentiated spondyloarthropathy than in normal controls. The frequency, type and severity of cardiac involvement in patients with ankylosing spondylitis were not different from those in patients with undifferentiated spondyloarthropathy.

Transpedicular screw instrumentation allows good fixation to the unstable spine after wide laminectomy procedure. The authors experienced 30 cases of transpedicular screw instrumentation in lumbar spine surgery, which had been operated from November, 1989 and had follow up at least for 6 months. We evaluated and reviewed the advantages and problems of transpedicular screw instrumentation through our experiences and literatures.

The authors reviewed computed tomography(CT) findings of spondylolylisthesis which composed of 20 cases of spondylolytic type and 20 cases of degenerative type. In most cases of spondylolisthesis, characteristic changes were seen at the corresponding pars interarticularis defects in spondylolytic type, and apophysial joints in degenerative type, each other.

Diurnally fluctuating hereditary progessive dystonia is a rare movement disorder characterized by marked diurnal fluctuation of symptoms and dramatic response to levodopa. We report two advanced female patients of two families who presented with progressive dystonia and gait disturbance. Both patients have a family history and showed excellent response to levodopa.

There have been limited reports about the prevalence and its characteristics of glaucoma in Korea. To clarify further, we retrospectively analyzed the data of 1482 patients with glaucoma from January 1993 to December 1994. The prevalence of glaucoma was 0.58%. The type of glaucoma consisted of secondary glaucoma 33.9%, primary open angle glaucoma(POAG) in 33.2%, angle closure glaucoma(ACG) 28.0%, normal tension glaucoma 4.0% and congenital glaucoma 0.9%. The mean age of the patients with POAG was 55.2+/-16.5 and that of ACG was 64.7+/-9.2. In POAG, the age group over 40 years old occupied 79.7% while 99.3% was the age group over 40 years in ACG. The incidence rate of men was higher than women in POAG but in women it was 3.6 times higher than men in ACG. Secondary glaucomas due to diseases of uveal tract, neovascular glaucoma, steroid induced glaucoma, and aphakic (or pseudophakic) glaucoma were 37.0%, 18.9%, 16.5%, and 15.7% respectively.

PURPOSE: We retrospectively performed this study to evaluate the characteristic findings of maxillomandibular ameloblastomas on CT and MR imaging. MATERIAS AND METHODS: We reviewed histologically proved 12 cases of ameloblastomas, of which 7 cases were postoperative recurrent tumors. one of twelve cases was presumed ameloblastic carcinoma. Eleven cases were examined with CT and 3 cases with MR. RESULTS: The types were solid in 4, unicystic in 4, and mixed in the rest 4. CT and MRI of 11 ameloblastomas showed concentric expansile mass(n=11), cortical bone thinning and focal bone destruction by the tumors(n=9), well-margined, expansile destruction of surrounding sturctures(n=9), focal bulging of the tumors(n=6) and focal poorly-marginated invasion of tissue planes(n=4). Ameloblastic carcinoma showed ill defined irregular margin, aggressive invasion of surrounding structures and hematogeneous lung metastasis. Unerupted teeth or mural nodules were found in unicystic ameloblastomas. All three tumors examined by MRI showed isointensity to muscle on T1 weighted images and slight hyperintensity on T2 weighted images. The wall, septa and solid portions of the tumors were strongly enhanced on MR imaging. There was no difference in CT or MR finding between primary and recurrent tumors. CONCLUSION: Ameloblastomas showed solid, cystic or mixed pattern, and commonly well marginated expansile contour with local aggressiveness. Presence of mural nodules on CT in unicystic ameloblastoma with unerupted tooth was helpful in distinguishing ameloblastoma from dentigerous cyst.
