Cystadenoma of the liver is a rare neoplasm. Although many cystadenomas are asymptomatic, symptoms can include abdominal pain, postprandial epigastric discomfort, and nausea. Dramatic changes in hepatic imaging techniques have been helpful for diagnosing cystic lesions of the liver, such as simple cyst, hydatid cyst, cystadenoma, cystadenocarcinoma, and metastatic neuroendocrine tumors. However, it remains difficult to differentiate cystadenoma from cystadenocarcinoma for multiseptated cystic hepatic lesions with papillary projection on computed tomography (CT) and magnetic resonance imaging (MRI). Here we report the case of a 47-year-old woman with several months of postprandial discomfort and abdominal fullness. CT and MRI revealed multiseptated cystic lesions with papillary excrescences. A left hemihepatectomy was performed. Histology showed a benign mucinous cystic tumor with ovarian-like stroma.

BACKGROUND: Respiratory depression with high dose of propofol during induction is one of the major complications. We studied the effects of midazolam as premedicant on frequency and duration of apnea and frequency of loss of consciousness in relation to single dose of propofol. METHODS: We selected 194 adult patients who had clear consciousness and no depression of respiration. We allocated patients randomly to control group and midazolam group. In midazolam group, we injected 0.06mg/kg of midazolam intravenously 10min before induction, and in control group, we did nothing. Under mask oxygenation with 100% oxygen, we administered a bolus of propofol (1, 1.5, 2 mg/kg to subgroup 1, 2, 3 respectively) intravenously. The change of respiration and loss of consciousness were observed. RESULTS: The frequency and duration of apnea increased with the dose of propofol in both control and midazolam group. But there were no difference between groups except frequency of apnea with 1.5 mg/kg of propofol. In control group, frequency of loss of consciousness increased with the increasing dose of propofol. But in midazolam group, nearly all the patients was slept without difference by the dose. CONCLUSIONS: Premedication with midazolam reduce the sleeping dose of propofol to induce anesthesia, so the frequency and duration of apnea which is caused by high dose of propofol can be decreased.

True congenital saccular aneurysms of distal posterior inferior cerebellar arteries are rare. We describe a 29 year-old female patient with subarachnoid hemorrhage in whom a nonmycotic saccular aneurysm arising from the tonsillomedullary segment of the left posterior cerebellar artery was demonstrated. This aneurysm was successfully clipped with good postoperative result. Brief review of the literature is also presented.

Sclerosing cholangitis is cholestatic disease, characterized by progressive fibrotic inflammation and obliteration af intrahepatic bile ducts and extrahepatic bile ducts and sometimes associated with ulcerative colitis. The pathogenesis of this disease is not understood well. In this disease, however, have been proposed infectious agent, endotoxin of bacteria and immunological event. In Europe and U.S.A., the incidence of sclerosing cholangitis associated with ulcerative colitis was between 2,4 and 4.0 percent. The association is strongest in patients with pancolitis, with a prevalenee of 5.5 percent, compared with patients with disease confined to the distal colon, with a prevalence of 0.5 percent. But, in Korea, it has not been reported sclerosing cholangitis associated with ulcerative colitis. A 30-year old man was diagnosed as an ulcerative colitis 9 years ago and has been followed up, intermittently. Recently, he has experienced hematochezia and dizziness. Colonoscopy showed active ulcerative colitis(pancolitis), blood chemistry elevated alkaline phosphatase and y-GTP. ERCP and liver biopsy specimen revealed sclerosing cholangitis. we concluded that this case was a sclerosing cholangitis as a complication of ulcerative colitis and the first case report of primary sclerosing cholangitis with ulcerative colitis in Korea, Hence, we reported a case of primary sclerosing cholangitis with ulcerative colitis with a review of literatures.

This study was designed to evaluate the potential applications of magnetic resonance imaging for the diagnosis of early and sequential changes of acute renal ischemia. Renal isehmia was induced in seventeen rabbits by surgical ligation of the left renal artery. Magnetic resonance imaging(MRI) was performed with a 2.0T super conductive MR system and s pin-echo technique was used with echo times(TE) of 30 and 80 msec and repetition times(TR) or 0.5 and 2.5 seconds. Kidneys were evaluated before and up to 48 hours after left renal artery ligation, and the spin echo images were analyzed for intensity difference and T1, T2 relaxation times between the cortex and the medulla of both kidneys. After one, and one and half hour following ligation of the left renal artery, the kidneys showed a 4-20% decrease in the left cortex compared to the right cortex contrast uptake(CCC) (P<01). There was a 14-29% decrease in left medulla to right medulla contrast uptake(MMC) (P<01). A 29-147% increase in contrast uptake was noted when the left cortex was compared to the left medulla(P<05). There was a 51-68% decrease in CMC of the right kidney (P<05) on three different spin echo images. In the cortex of the left kidney, T2 relaxation time decreased 14% (P<01). CCC and MMC showed more prominent changes than CMC, and sequential changes of CCC and MMC were most prominent on T2 weighted images with TR = 2.5sec and TE=80msec when compared with T1 weighted and proton density weighted images. Twelve hours after renal arterial ligation. T2 relaxation time, CMC, CCC, and MMC returned to normal values and these findings were believed to be due to congestion and collateral blood supply. In renal ischemia, the most useful MRI findings for diagnosis were fund to be changes of CCC and MMC on T2 weighted image, and T2 relaxation time of the cortex in the ischemic kidney.
