PURPOSE: To evaluate the surface anatomy of the central sulcus(CS), precentral gyrus(PrCG) and postcentral gyrus(PoCG) on the basis of sulci pattern on MR images. MATERIALS AND METHODS: The MR images were obtained in the plane 10 degree angled to the orbitomeatal line. The MR images of 120 subjects(6 months to 79 years) with normal anatomy were analyzed and another four subjects with known space occupying lesions were also reviewed. RESULTS: The identification of gyri was feasible on the axial T1WI from anterior to posterior and from upper to lower images. The STS demonstrated symmetric pattern on both sides in 84 of 120 cases (70%), including two cases of prominent STS pattern. The asymmetric pattern was seen in 36 of 120 cases (30%):14 of 120 cases (12%) on the right and 22 of 120 cases (18%) on the left at 4.5 cm above the level of the splenium of corpus callosum. The PrCG and PoCG and CS were identified well in all cases with the use 'of the sulci pattern. CONCLUSION: The identification of the gyri on the basis of the cerebral sulci pattern on MR images is useful and important when locating the space occupying lesion of the brain.

PURPOSE: We experienced a patient with posttraumatic duplication of the sternoclavicular joint causing a protruding deformity, whose major complaint was aesthetic. The patients history, radiologic findings, and surgical treatment are reported. METHODS: A 41-year-old bus driver complained a bony prominence at the left medial clavicle, which had developed after a fracture. The patient was annoyed by the protrusion, which was even visible, when he was wearing a pullover. A three dimensional CT scan showed that the medial head was split into two portions, of which the anterior portion was protruding. In general anesthesia the anterior portion of the medial head was excised. RESULTS: The bony prominence was corrected successfully. Follow up three dimensional CT scans showed that the anterior cortex of the clavicle had regenerated completely at the resection line one year after the operation. CONCLUSION: Surgical interventions for complications after clavicular fracture are usually carried out, only if there is a limitation of function or if it is painful. We report of a patient with posttraumatic bifurcation of the medial clavicular head, most probably caused by malunion. Upon the patient's request, the deformity causing protrusion of the medial clavicular area was successfully resected for cosmetic reasons.

PURPOSE: Lipomas of the skin are one of the most frequently encountered tumors in plastic surgical practice. Huge lipomas of all areas of the body have been described. Large lipomas of the face, however, are not so common. We report on the treatment of a huge lipoma of the forehead causing distortion of the eyebrows. METHODS: A 55 year old man was referred to our department by the neurosurgeons. He was primarily admitted for removal of a meningioma of the left frontal lobe of his brain. More striking was a huge protruding mass of 75x60x30mm covering almost the whole left half of his face's upper third and displacing his left eyebrow downward by almost 1cm. MRI showed a large lipoma, which caused 3cm anterior protrusion of the overlying skin. A meningioma of the left frontal lobe was also seen. The lipoma was removed via an external approach. Before closure of the skin a 3.5 cm wide strip of muscle and skin was resected. The multilobulated specimen was covered by a thin capsule and weighed 95g. The pathologist diagnosed it as benign lipoma. RESULTS: The postoperative course was uneventful. At 11 months after the operation the resulting scar was inconspicuous, the position of the eyebrows was almost symmetric and a symmetric brow elevation was observed. CONCLUSION: We describe the largest facial lipoma reported in the recent literature. By using an open approach, skin excision and redraping, we achieved an aesthetically satisfactory outcome.

An upward slant of palpebral fissure is usually said and believed to be a hallmark of Mongolian race. The slant of palpebral fissure is very important in the evaluation and treatment of patients with congenital deformities. And these statistical values of slant of palpebral fissures are very helpful in case of traumatic or congenital lateral canthal deformities and upper face lift or forehead lift. The normal values of slant of palpebral fissures are variable according to races, sex and ages. Even if upward slant of palpebral fissure are one of characteristic features of Koreans, there are a few articles concerning them in Korea yet, unfortunately. So, we have inevitably utilized the Caucasian or Japanese statistical data. Authors measured the slant of palpebral fissure in Koreans, and statistically analyzed them in 996 individuals including 468 males and 528 females. The mean values of slant of palpebral fissure was 8.5+/-2.0degreein males and 8.8+/-2.5degreein females. The mean values of slant of palpebral fissure was greater in female than male. However, there was no statistical difference between males and females. The slant of palpebral fissure reached the peak level at childhood and teenagers in a great portion. After the peak level, the changing pattern of slant of palpebral fissure was decreasing gradually. In summary, we consider 8.65degreeas normal standard value of slant of palpebral fissure when performing lateral canthal surgery in Koreans.

Osteomalacia is a disorder in which the mineralization of the organic matrix of the skeleton is defective. Proximal muscular weakness is a common symptom of osteomalacia. A 27-year-old woman reported the gradual onset of gait disturbance and bone pain in the thigh. Her height shortened during 10 months. On neurological examinations, proximal muscular weakness of the extremities was disclosed. Serum phosphorus was 1.8 mg/dl (normal 2.5~4.5), alkaline phosphatase was 1045 IU/L (normal 70~290), and 1,25 (OH)2 vitamin D3 was 18 pg/ml (normal 20~60). On roentgenography, multiple pseudofracture lines of the rib and erosion of the head of the right femur were demonstrated. A bone scan showed multiple hot spots on the ribs and right femur. She was medicated with calcitriol and phosphorus and she recovered most of her strength and experienced decreased bone pain after 3 months. We report a case that confirms osteomalacic myopathy by an endocrinological test in patients who experienced gradual proximal muscular weakness and bone pain.

OBJECTIVE: To describe normal postoperative MR findings and MR findings of postoperative discitis in patients who underwent operation due to herniated intervertebral disc. MATERIALS AND METHODS: We retrospectively reviewed normal postoperative MR findings and MR findings of discitis in 30 patients(21-61yrs.) (13 cases dignosed as discitis and 17 cases as normal) who previonsly underwent laminectomy and discectomy, or bony fusion. We analyzed signal intensity of end plate and disc, end plate destruction, and enhancement of end plate and disc on T1- and T2-weighted images(WI) of 1.5T MRI. RESULTS: Among 14 out of 17 patients with no evidence of discitis, 7 patients showed high signal of the posterior portion of disc on T1- and T2-WI and 11 patients revealed enhancement at the same sites. In all 13 patients suspected of having discitis, end plate and disc showed low signal on T1-WI, high signal on T2-WI, heterogeneous enhancement, and irregular destruction of end plate. Meanwhile, 3 cases with no evidence of postoperative discitis clinically who underwent bony fusion showed similiar findings to those of the above 13 patients, except for homogeneous enhancement of end plate and vertebral body. CONCLUSION: The MR findings of postoperative discitis were low signal on T1-WI, high signal on T2-WI, and heterogeneous enhancement of and plate and disc, and destruction of end plate.

PURPOSE: The purpose of this study was to evaluate the spectrum of MR characteristics of cystic acoustic neurinomas and to correlate with pathologic findings. MATERIALS AND METHODS: We retrospectively reviewed the MR findings of 12 patients with cystic acoustic neurinomas. The signal intensity and enhancement pattern of the cystic components as well as the location relative to the tumors were analyzed. RESULTS: A total of 30 cysts were found in 15 acoustic neurinomas;28 were intratumoral cysts and the remaining two were extratumoral cysts. The signal intensity of all 28 intratumoral cysts was higher than that of CSF on Tl-weighted images, and isointense to CSF on T2-weighted images, while the signal intensity of the two extratumoral cysts was same as CSF on both Tl-weighted and T2-weighted images. Rim enhancement was seen in 27 of 28 intratumoral cysts but in none of the two extratumoral cysts. CONCLUSION: We concluded that intratumoral cyst was due to tumoral necrosis, hemorrhage or degenerative change and extratumoral cyst due to secondary arachnoid cyst formation.
