We found multiple aneurysms in the intracranial arteries and abdominal aorta of an 87-year-old Korean female cadaver, whose cause of death was reported as "cholangiocarcinoma." An abdominal aortic aneurysm was observed in the infrarenal aorta, where the inferior mesenteric artery arose. The intracranial aneurysms were found in the A3 segment of the anterior cerebral artery and at the bifurcation of the middle cerebral artery. This case provides an example of the very rare association of peripheral intracranial aneurysms with an abdominal aortic aneurysm. Clinicians as well as anatomists should recognize the potential association between these two aneurysm types.

PURPOSE: To compare the detectability and conspicuity of focal hepatic lesions among conventional spin echo techniqueniques and fast scanning techniqueniques in MR imaging. MATERIALS AND METHOD: 36 patients (24 men and 12 women, mean age of 54 years) with suspected liver mass on CT scan and US underwent MR imaging at 1.5 T system. Conventional spin echo T1, T2 weighted imaging, T2 weighted fast spin echo, T1 weighted fast multiplanar spoiled gradient recalled(FMPSPGR) imaging and Gd-enhanced FMPSPGR(Gd-FMPSPGR) were performed. 16 cases of hepatocellular carcinoma, 13 cases of hemangioma, 3 cases of metastasis, 3 cases of cholangiocarcinoma, and 1 case of lymphoma were included. Lesion conspicuity and number of detected hepatic masses were compared among the MR sequences. RESULTS: Overall 63 hepatic lesions were detected in 36 patients. Lesion detection' was 63(100%) with Gd-FMPSPGR, 62(98%) with non-enhanced FMPSPGR, 58(92%) with SE T2WI, 56(89%) with SE T1WI and 54 (86%)with FSE. For solid tumors, the contrast to noise ratio was greatest on Gd-FMPSPGR which was significantly higher than any other sequences. For hemangiomas it was greatest on SE T2WI and was significantly higher than SE T1WI. In the qualitative assessment, Gd-FMPSPGR was preferred for both solid mass lesion and hemangioma. FSE was inferior to SE T2WI for lesion detection and conspicuity without statistical significance. CONCLUSIONS: For the evaluation of focal hepatic lesions, breath-hold FMPSPGR with and without contrast enhancement may replace the conventional SE T1WI. Because FSE was inferior to SE T2WI when the later is used with respiratory compensation in some cases, it is difficult to replace the SE T2WI with FSE. But FSE, FMPSPGR and Gd-FMPSPGR images, when combined, may replace SE T1WI and SE T2WI.

Mauriac syndrome consists of a triad of poorly controlled diabetes, profound growth retardation and hepatomegaly. We experienced a case of Mauriac syndrome in an 18-year-old girl who had poorly controlled diabetes mellitus, short stature, hepatomegaly and central obesity. Also at the time of examination, she had complications of diabetic cataract and nephropathy. Fourteen years prior to admission, she was diagnosed as diabetes mellitus at a hospital. Thereafter, she had been managed with irregular insulin injection. On physical examination at admission, her height was 135cm(<3 percentile) and her weight was 39kg(<3 percetile). She was short and obese. The liver was 5 cm palpable below the right subcostal margin. Her sexual maturation was Tanner stage I. On ophthalmologic examination, the cataracts were observed on both eyes and diabetic retinopathy was absent. Diabetic nephropathy could not be confirrned by kidney biopsy due to her mother's refusal. We studied the hormonal, radiographic and histological abnormalities. The hormonal study was normal and the bone age was by delayed as much as 10 years. The liver biopsy revealed glycogen accumulation in hepatocyte. She was consistent with Mauriac syndrome. She was managed by strict diabetic control with insulin therapy, diabetic diet and intensive education. She was discharged with well controlled blood glucose. Five months later, growth acceleration and sexual maturation have not been observed, but hepatomegaly subsided. (J Korean Pediatr Soc 2000;43-837-841)

Studies in animals indicate that aconitine or aconite has toxic effects in the visual system of a rabbit model. Such a toxic effects causes myelo-optic neuropathy in the visually evoked cortical potential(VECP) and histopathologic studies. Whether the administration of intravenous high-dose of methyprednisolone(MP) in the myelo-optic neuropathy caused by aconitine(1.5ml/kg, equivalent to 0.7mg/kg of aconitine) is experimentally effective remains uncertain. The group treated with MP(daily 30mg/kg X 2 for 3 days followed by 15mg/kg for 3 days) in addition to aconite was compared with the aconite alone group and the normal control group. In the MP treated group, increased recovery of onset latency, peak latency, and amplitude in VECP in comparision with the aconite alone group was recorded at 2 weeks (p<0.05). The MP treated group in comparision with the normal control group showed a significant delay in onset latency at 1 month and 2 months(p<0.05). But, the amplitude in both the MP treated group and the aconite alone group increased at 2 months and did not show a significant difference in comparision with the normal group(p<0.05). In histopathologic study, pathologic findings of myelin sheath in the MP treated group were less severe than in the aconite alone group generally. The true benefit of high-dose MP was at least clear within 2 weeks. The authors conclude that treatment with intravenous high-dose MP immediate after aconite injection may have some beneficial effects in recovery of neurologic function although such a treatment do not have the definite recovery in aconite induced myelo-optic neuropathy.
