PURPOSE: To evaluate the MR appearance of the accessory hepatic veins. MATERIALS AND METHODS: The study included 87 consecutive patients for whom abdominal MR images were obtained. The subjects who had liver lesion or hepatic vascular abnormalities were excluded. Couinaud classified accessory hepatic veins into inferior and middle right hepatic veins. Our major interests were evaluation of the incidence, morphology, and location of the accessory hepatic vein. RESULTS: Inferior right hepatic vein was demonstrated in 43 out of 87 patients(49%). The morphology was linear in 35 patients(80.5%), and V-shaped in 8 patients(19.5%). In 40 patients(93%), the inferior right hepatic vein was located in the posteroinferior aspect of the right lobe. Middle right hepatic vein was demonstrated in 7 out of 87 patients(8%). All were single linear in morphology, combined with the inferior right hepatic vein, and located between the right hepatic vein and inferior right hepatic vein. CONCLUSION: The accessory hepatic vein was demonstrated in 49% among the Korean adult population, and was located in posteroinferior portion of the liver, in 93%.

Glomeruloid hemangioma is a histologically distinctive cutaneous angioma which is rarely de-scribed in patients with POEMS (polyneuropathy, organomegaly, endocrinopathy, M-protein, and skin changes) syndrome and multicentric Castleman's disease. We report an additional case of glomeruloid hemangioma in a 30-year-old Korean woman with multicentric Castleman's disease showing features of POEMS syndrome. Histopathology revealed multiple dermal dilated vascular spaces composed of a conglomerate of capillaries, resulting in structures reminiscent of renal glomeruli. Periodic acid-Schiff-positive and diastase-resistant eosinophilic globules were found within the cytoplasm of vacuolated endothelial cells. The endothelial cells lining the capillary loops showed positive immunostaining for factor VIII-related antigen and CD31.

PURPOSE: To compare the macular choroidal thickness, ganglion cell complex thickness, peripapillary choroidal thickness and retinal nerve fiber layer thickness among normal, primary open angle glaucoma (POAG) and normal tension glaucoma (NTG) patients using RTVue (Fourier-domain optical coherence tomography; Optovue, Fremont, CA, USA). METHODS: A retrospective analysis of 32 normal controls, 32 POAG and 52 NTG patients was performed. Choroidal thickness, ganglion cell complex thickness and retinal nerve fiber layer thickness were compared among normal controls, POAG and NTG subjects. Additionally, the factors influencing choroidal thickness (age, axial length, spherical equivalent, central corneal thickness, mean deviation, nocturnal dip, blood pressure variability) were analyzed. RESULTS: A total of 32 normal controls, 32 POAG and 52 NTG patients were enrolled in this study. Macular and peripapillary choroidal thicknesses were significantly thinner in the NTG patients. In NTG subjects, the significant influencing factors associated with macular and peripapillary choroidal thicknesses were age, axial length, nocturnal dip (diastolic blood pressure), diastolic blood pressure variability and ganglion cell complex thickness. In POAG patients, significant influencing factors associated with macular and peripapillary choroidal thicknesses were age and axial length. CONCLUSIONS: Choroidal thickness was significantly thinner in NTG patients compared with normal controls and POAG patients. Factors influencing choroidal thickness in NTG patients were age, axial length, nocturnal dip (diastolic blood pressure), diastolic blood pressure variability and ganglion cell complex thickness. In POAG patients, significant factors influencing choroidal thickness were age and axial length.

We reviewed clinicoradiologic findings of twenty-one patients with lateral medullary(Wallenberg) syndrome who admitted at Seoul National University Hospital from March, 1983 to February, 1989. The results are as follows: 1. Lateral medullary syndrome was 14.6% of ischemic stroke in vertebrobasilar territory during the same period. The ages ranged from 35 to 69 years and most of them were in 6th or 7th decades. Z. Detected risk factors were hypertension in 17, previous stroke in 8, hyperlipidemia in 7, and diabetes mellitus in 4. 3. The interval which developed maximal characteristic symptoms after onset were within 5 days in all patients and 2 days in 13 patients. 4. Frequent complaints were dizziness in 21, vertigo in 17, nausea or vomiting in 18, swallowrng difficulty in 14, dysarthria in 12, headache in 11, hoarseness in 7, hiccup in 7, and facial pain in 3, 5. Frequent signs were Horner's syndrome in 21, ataxia in 21, crossed sensory change in 19, soft palate sagging in 15, ipsilateral facial weakness in 9, DTR increase in the same side in 7, tongue deviation in 6, transient diplopia in 5, and transient altered consciousness in 4, 6. Disease courses were considerable improvement in 18, recurrence in 1, and discharge against medical advice in 1. Frequent disturbing complaints during the follow-up period were paresthesia or sensory loss in 16 and ataxia in 11. 7 Among the radiologic studies, MRI could define the lesion at corresponding site in 8 of 9, CT in 3 of 21, and TFCA in 3 of 6. These results suggest that MRI is the best rdiologic study to yeild the lesion in lateral medullary syndrome.

The systolic time intervals were measured in 25 normal controls and 23 patients with dilated cardiomyopathy by simultaneous recording of the aortic valve echocardiogram and ECG. These values were compared to corresponding ones obtained from the method using simultaneously recorded phonocardiogram, ECG, and indirect carotid pulse tracings. And we assessed left ventricular function by systolic time intervals in dilated cardiomyopathy. The results were as followings. 1) High degree of correlation(r> or =0.94) was found between the two methods for each intervals, EMS, LVET, PEP, PEP/LVET. 2) In normal controls, PEP/LVET obtained from echocardiographic measurement was 0.31+/-0.02. 3) In the patients with dilated cardiomyopathy, PEP/LVET(0.59+/-0.13) was significantly higher(p<0.001), PEP index was longer(p<0.05), LVET index was shorter(p<0.05) than in normal controls.
