PURPOSE: The purpose of this study was to determine the role of CT and MR imagings in the diagnosis aortic dissection and differentiation between the true and false lumen. MATERIALS AND METHODS: We retrospectively studied forty patients with aortic dissection(AD) diagnosed imagings or surgery. Of the forty patients, 19 were examined with only CT, 14 with CT and MR, and 7 with MI~: Our points of view were(1) the classification of AD according to configuration of intimal flap by cross-sectional imaging, (2) differentiation between the true and false lumens, (3) the course of the false lumen, and (4)! detectability of the origin of major branch vessels of the abdominal aorta. RESULTS: The classification by corss-sectional imaging were crescentic(65%), circumferential(15%), flat(12%), and irregular(8%) type, in which false negative diagnosis was made in 1 case of crescentic and circumferential type, respectively. In 2 case of flat type and 1 case of irregular type, the differentiation between the true and false lumen was impossible with CT. The course of the false lumen in descending thoracic aorta revealed countrclock wise rotation(66%), clockwise rotation(5%) or fixed(29%) apperance. MR imaging was superior to CT in the detection of the origin of major branch vessels of the abdominal aorta. The determination of the origin of major branches of abdominal aorta arising from the true and false lumen were impossible in 2 cases in which only CT was done. CONCLUSION: Diagnosis of crescentic and circumferential types of AD with narrow and thrombosed false lumen was problematic in both CT and MR with no difference of diagnostic accuracy between the two modalities. The differentiation between the true and false lumen was difficult in flat and irregular types with only CT. Therefore, when surgical treatment is considered as in type B aortic dissection, MR imaging is recommended in order to determine the origin of major branch vessels.

BACKGROUND: It has been well known that absolute and interpeak latencies of brainstem auditory evoked potentials (BAEP) are usually prolonged in diabetics. However, Its etiology is still controversial. We tried to identify whether the cause is structural or metabolic in origin by performing BAEP and brain MRI in the diabetic patients. METHODS: BAEP were performed in both the diabetic patients (DM) group (16 males and 15 females) and the normal control group (25 males and 33 female). A brain MRI was performed in the DM group on those who showed abnormal BAEP and com-pared the results of BAEP of the DM group with those of the control group. RESULTS: 7 patients (22.6%) showed abnor-mal BAEP (male; 6, female; 1, unilateral; 4, bilateral; 3) when abnormal BAEP was defined as being larger than two and a half standard deviations of the control group BAEP results. Two males of the DM group who showed abnormal structural lesions of the pons in their brain MRI were not included in the statistical analysis. The remaining 14 diabetic male patients (mean age: 58.7 +/-9.1 years, mean disease duration: 6.1 +/-4.7 years, mean hemoglobin (Hb) A1C: 7.7 +/- 2.0%) and 15 diabetic female patients (mean age: 60.6 +/-10.8 years, mean disease duration: 5.4 +/-5.1 years, mean HgA1C: 7.8 +/-2.1%) were stastistically analyzed. Interpeak latencies of I-III, III-V, and I-V were found to be signifi-cantly prolonged in the DM group. The prolongation of interpeak latencies of I-III and I-V were found to be signifi-cantly correlated with the disease duration only in the diabetic female patients, but not with age and HbA1c. CONCLUSIONS: These findings suggest that both metabolic derangement and structural lesion contribute to prolonging the central conduction time on BAEP pathway in diabetics.

Background: Brain MRI may unexpectedly display abnormalities in splenium of the corpus callosum
(SCC). However, the clinical implications of this lesion are unclear and are not always consistent
with ischemic infarctions. We performed this study to clarify the clinical and radiological implications
in patients with SCC lesions. Methods: We retrospectively reviewed consecutive patients with MRIreported
SCC changes between 2009 and 2012. We analyzed clinical and radiological findings,
etiologies, cognitive impairment, and clinical outcomes. Results: We found 30 patients (16 females;
mean 50.5 years) who had SCC lesions on MRI. Confusion was the most common clinical finding
in 50% of cases. Cerebral infarction was the most common etiology (50%). The most consistent
SCC changes on MRI were low signal in T1WI, high signal on T2WI and FLAIR, and high signal
on DWI. We classified SCC lesions into in situ SCC lesions (SCC only) and multiple (SCC plus)
lesions for patients with multiple lesions. The clinical symptoms of SCC only lesions were relatively
mild. Cognitive functions were evaluated by Mini Mental State Examination (MMSE) and clinical
dementia rating (CDR) scale at the time of discharge and patients with SCC only lesions showed less
impaired cognition compared with those with SCC plus lesions. Clinical outcomes were evaluated
by the modified Rankin scale at 1 month and patients with SCC only lesions revealed good clinical
outcomes compared with those with SCC plus lesions.
Conclusions: MRI-reported SCC lesions may have heterogeneous etiologies and present with various
symptoms. The clinical course and outcome are relatively good, particularly in small isolated and
oval shaped SCC lesions.

Objectives:
This study investigated the relationship between clock-drawing test (CDT) performance and neuropsychological functions in patients with chronic schizophrenia.
Methods:
Thirty-one patients with schizophrenia and 30 healthy controls participated in this study. The CDT was administered in three conditions and analyzed using both quantitative and qualitative scoring systems. Comprehensive neuropsychological tests were administered.
Results:
The results of the quantitative analysis showed that the schizophrenia group performed significantly worse in all three conditions of the CDT compared with the control group. However, no significant differences were observed between the two groups, when the IQ and educational level were controlled. The qualitative analysis showed that the schizophrenia group exhibited significantly more errors in “graphic difficulty” compared with the control group. In addition, CDT quantitative scores were significantly correlated with visuospatial function, memory, attention and executive functions in patients with schizophrenia. Conversely, each qualitative error type was correlated with specific cognitive domains. Furthermore, “graphic difficulty” and “spatial/ planning deficit” were identified as predictors of depression symptoms in patients with schizophrenia.
Conclusion
The present study demonstrated that the CDT is useful for assessing cognitive dysfunctions in patients with schizophrenia, while qualitative analyses provide more specific information about cognitive deficits compared with quantitative analyses.

Dupuytren's contracture is characterized by a proliferative fibroplasia and contracture of the palmar fascia with resultant deformity of hand and finger. It is most common in those of Scandinavian and Celtic origin but it is very rare in the orientals. We experienced 30 hands of 21 patients from January 1985 to December 1995 in Soonchunhyang University Hospital. Among 21 patients, operative treatment was done in 28 hands of 19 patients. Partial fasciectomy was done in 24 hands and complete fasciectomy was done in 4 hands. The longitudinal straight skin incision was done in 14 cases and the transverse or Zig-Zag incision was done in 12 cases. Average follow-up period was 24 months. The results of the operative treatment were classified by Honner's classification. Excellent result was obtained in 16 cases (57%), good in 8 (29%), fair in 3 (11%), poor in 1 (3%). The complications were 5 cases as follows; recurrence 2, skin defect 1, hypoesthesia 2. In conclusion, partial fasciectomy utilizing longitudinal straight incisions overlying diseased area is suggested as one of the good method for the treatment of Dupuytren s contracture.

Surgical resection is the best treatment for operable metastatic liver cancer. Large metastatic cancer usually has low operability, so a debulking modality of mass is needed to increase operability. Chemotherapy and radiotherapy were commonly used as neoadjuvant treatments. Cyberknife stereotactic radiosurgery systems were only considered as one of the palliative treatment modalities for inoperable or surgically complex tumors. But, in this case, we applied Cyberknife as the preoperative debulking modality for large hepatic metastasis of adrenocortical carcinoma. After Cyberknife treatment 3 cyclex2,700 cGY, tumor size decreased (metastatic liver mass decreased to 15x9 cm from 19x12.5 cm, adrenal mass decreased to 5x3 cm from 7.4x4.5 cm). We could then resect the tumor completely by extended right hemihepatectomy & right adrenalectomy. A preoperative multidisciplinary approach, including chemotherapy and radiation therapy can be considered to increase operability. So, cyberknife can be considered an additional modality as a neoadjuvant radiotherapy.
