The carotid stump is a known source of cerebral embolisms. Direct ultrasound sonographic visualization of a thrombus in the common carotid stump after development of a cerebral infarction is rare. We report a case of a 69-year-old man who presented with acute ipsilateral ischemic stroke with occlusion of the left common carotid artery, forming a stump proximal to the carotid bifurcation. Carotid duplex sonography revealed a mobile thrombus in the stump. An ipsilateral microembolic signal was observed by transcranial Doppler imaging.

OBJECT: To analyze clinical'data about the patients presenting with altered consciousness in the emergency room and to plan adequate evaluations and managements. BACKGROLTND. Clinical analysis of comatose patients is necessary. We have a few reports but they don't give enough clues to evaluate the patients rapidly and systematically. METHOD: We included the patients with altered consciousness on the base of the daily reports of emergency room, and reviewed the medical records of the patients. We analyzed the age, sex, visiting date, the patterns of discharge of emergency room, underlying causes, and consequences of the patients. The validity of the contents of daily reports was tested by pilot study. In pilot study, we examined all patients entering emergency room for a week, and compared contents of daily reports with the data acquired from direct examination. RESULTS: The pilot study revealed that the method of patient selection had no problem statistically. The nwnber of patients with altered consciousness entering emergency room, was 594 for one year. The causes of altered consciousness consisted of metabolic problem (35.4%), hemorrhagic stroke (21.2%), malignancy (9.26%), nonhemorrhagic stroke (8. 1%), and others. The causes of metabolic coma werehepatic encephalopathy (69.5%), glucose and electrolyte problem (12.9/o), drug intoxication (6.67%), uremic encephalopathy (6.19%) and alcohol related illness (4.76%). Metabolic coma patients showed better prognosis than others, and hemorrhagic stroke and malignancy showed poor prognosis. The ischemic stroke patients were older than others. Considering the age of the patients, the younger men had better clinical courses than elderly. Significant seasonal variation was notfound. CONCLUSION: The patients visitmg emergency room with altered consciousness had various causes. The most common cause was metabolic origin followed by hemorrhagic stroke. Under the influence of the improvement of socioeconomic status and longevity, the distributions of the underlying disease have changed. The prognosis and consequence of them relied on underlying diseases and age.

The purpose of this study was the presence of accessory tendon and its anatomical variation of insertion of the abductor pollicis longus and extensor pollicis brevis. 1. Among 46 cases, all had one or more accessory tendon except one which inserted into the base of the first metacarpal bone on its anterolateral surface with a single tendon. 2. Among 45 cases (which had one or more accessory tendon), the abductor pollicis longus tendon inserted into the trapezium in 30 cases(66.6%), and thenar muscles in 38 cases (84.4%). 3. Among 46 cases, the extensor pollicis brevis tendon inserted into the proximal phalanx in 30 cases(65%) and into the distal phalanx with extensor pollicis longus in 8 cases (18%) and into both in 8 cases (18%). 4. Among 22 cadavers, symmetry of insertion of the abductor pollicis longus noticed in 16 cases (88 and extensor pollicis brevis in 21 cases (95%).

BACKGROUND: We attempted to see if acute MRI can expand the time window of thrombolytic therapy in acute stroke. METHODS: We performed MRI protocol including diffusion-weighted image (DWI) and MR angiogram (MRA) for patients with stroke within 6 hours after symptom onset. We selected 58 patients who had occlusion of middle cerebral artery (MCA) on the initial MRA. Thrombolytic therapy was done only when the patients showed more severe neurological deficits than expected with DWI findings. We analyzed demographic features, initial and follow-up NIH stroke scale scores, recanalization, and hemorrhagic transformation after thrombolytic therapy in 2 groups which were classified according to time to check MRI (within or beyond 3 hours). We measured the initial and follow-up lesion volume detected by DWI. RESULTS: Thrombolytic therapy was done in 38 patients. Twenty-four patients underwent MRI within 3 hours, and 14 patients underwent MRI between 3 and 6 hours. There were no significant differences in baseline characteristics, recanalization rate, ratio of marked clinical improvement, and hemorrhagic transformation rate between 2 groups. Young age was a significant predictable factor for good clinical outcome (p<0.05), but the interval from onset to imaging time and treatment modalities were not. CONCLUSIONS: It is suggested that patients' age and DWI findings are more appropriate factors affecting the clinical outcome after thrombolytic therapy than time interval itself at least when the therapy is considered within 6 hours.

Leber's hereditary optic neuropathy (LHON) is an important cause of bilateral optic neuropathy in youth and occasionally associated with other neurological abnormalities (Leber's plus). The authors recently found out one family of LHON and another patient of Leber's plus with mitochondrial DNA (mtDNA) 11778 mutation. The presence of a point mutation of mtDNA was investigated by restriction length fragment polymorphism. Among 14 patients who had mtDNA 11778 mutation in the family, only two men had bilateral optic neuropathy. The other was a man of optic neuropathy with myelopathy. The age at onset of visual loss ranged from 14 to 25 (average 19.7). The time delay between involvement of the two eyes was I to 3 months Central visual field defect was observed in each of all affected eyes and worse in the earlier affected. The brain MRI and CSF studies revealed no abnormality. This study showed that the clinical manifestations and genealogical features of LHON in our patients are similar to those of previously reported cases in other countries.

Herpes simplex encephalitis (HSE) is the most common form of encephalitis, with predilection for the temporal lobes and insular cortex. The presence of RBCs is a characteristic finding of CSF analysis and hemorrhagic transformation of the lesions on CT or MRI is not a rare, because the hemorrhagic necrosis is an important pathologic finding of HSE. However, intracerebral hematoma is rarely reported. We report a case of PCR proven HSE with hemotomas in both the medial temporal lobes, which has not been reported.

Inflammatory demyelinating diseases are usually diagnosed based on characteristic clinical and radiological findings. However, some demyelinating diseases have been presented as growing large mass-like lesions, and it is difficult to differentiate those demyelinating lesions from brain tumors. We report three cases of demyelinating diseases mimicking brain tumors. These cases suggest that the inflammatory demyelinating diseases have a wide spectrum and they can present with the same radiological features of brain tumors.
