A 6(1/2)-year-old girl developed recurrent cholangitis following hepatic portoenterostomy for biliary atresia. Computed tomogram showed an ovoid cyst (4.5 x 4.0 cm in size) in the left hepatic lobe and another tubular dilatation (2.0 x 0.8 cm in size) in the right hepatic lobe. Percutaneous transhepatic cholangio-drainage (PTCD) with cystogram showed an ovoid cyst in the left hepatic lobe (Tsuchida type A), measuring 6.6 x 5.0 cmin size. She became afebrile and anicteric with aid of PTCD and parenteral antibiotics. However she continued to drain 45-150 cc of bile per day via the tube for over 2 weeks. Then she successfully underwent intrahepatic cystojejunostomy with guidance of intraoperative ultrasonography. This case illustrates relapsing cholangitis caused by Tsuchida type A intrahepatic cyst, which was successfully managed with PTCD followed by internal drainage procedure.

This paper includes our 9-year experience of 34 infants with biliary atresia with introduction of a new non-invasive diagnostic method, that is, ultrasonographic "triangular cord" (TC) sign. TC sign was defined as visualization of a triangular or a band-like echogenicity just cranial to the portal vein. Ultrasonographic TC sign seemed to be a simple, non-invasive, time-saving and useful tool in the diagnosis of biliary atresia, representing 84% sensitivity. Active bile excretion was restored in 90% of the patients who were treated between 31-60days, 78% of those between 61-90 days, and 33% of those being 91days or older. The incidence of postoperative cholangitis was 36%, and construction of antireflux valve in the Roux-en -Y loop did not affect the incidence of postoperative cholangitis (P=0.18). As for the surgical outcome, of 34 infants with biliary atresia, 23 (68%) are alive for 2-102 months period, and 12 of them are alive for more than 5 years . Five-year estimate survival by Kaplan-Meier method was 66 %.

PURPOSE: The purpose of this study is to evaluate the gadolinium-enhanced MR imaging findings of cerebral venous angiomas, and to compare those findings with those of cerebral angiography. MATERIALS AND METHODS: We reviewed the findings of gadolinium-enhanced MR images of 11 cases with angiographically proved cerebral venous angiomas. We obtained Tl-and T2-weighted images with gadoliniumenhanced Tl-weighted images at a 0.5 T MR imager with a spin-echo technique. We analyzed the location and signal intensity of the lesion, pattern of contrast enhancement, the distribution of draining veins and medullary veins before and after contrast enhancement, and then compared with the findings of cerebral angiography. RESULTS: The characteristic central tubular signal void structure showed low signal intensity on Tl-weighted images and high signal intensity on T2-weighted images in all cases. After gadolinium enhancement, we could find a characteristic enhancement of all medullary and central veins in 7 cases. CONCLUSION: Gadolinium-enhanced MR image was useful in the diagnosis of venous angiomas especially in the detection of medullary veins. The invasive cerebral angiography could be replaced by this technique in this disease.

Intercellular adhesion molecule-1 (ICAM-1) and vascular cell adhesion molecule-1 (VCAM-1) are weakly expressed in normal glomerular cells and vascular endothelial cells, but not in tubules. Granzyme B is a cytotoxic granule present in activated cytotoxic T cells and natural killer cells. To determine the effect of ICAM-1 and VCAM-1 expression and granzyme B-positive cells on histologic grade of rejection, we performed the immunohistochemical study on 19 renal biopsy specimens and one nephrectomy specimen from 14 patients with acute renal allograft rejection using monoclonal antibodies against theses proteins. According to severity of rejection based on Banff classification, three biopsies were classified as borderline, 4 grade I, 12 grade II, and 1 grade III. In all the cases with acute rejection, ICAM-1 and VCAM-1 were expressed in the tubular epithelial cells. The numerical score of ICAM-1 in the tubular epithelial cells was 1.0 in borderline cases, 1.3 0.4 in grade I cases, 2.2 0.8 in grade II cases, and 3.0 in grade III case. The staining intensity of ICAM-1 in the tubular epithelial cells was increased in accordance with histologic rejection grade (P<0.05). The staining intensity of ICAM-1 and VCAM-1 in the renal tubular epithelial cells was increased in accordance with the number of T lymphocytes in the renal parenchyme (r=0.46; P<0.05, r=0.61; P<0.01). The number of granzyme B-positive cells was 6.4 1.6/HPF in borderline cases, 8.1 2.5 in grade I cases, 19.6 11.7 in grade II cases, and 53 in grade III case. The number of T lymphocytes and granzyme B-positive cells was also increased in accordance with histologic rejection grade (P<0.05). These results suggest that ICAM-1 and granzyme B-positive cells may play an important role in the induction of renal allograft rejection and that the grading of severity of these parameters may be useful to predict the prognosis of renal allograft.

Primary segmental volvulus (PSV) of the ileum in neonate occurs rarely but shows an aggressive clinical course. Thus, early diagnosis is important to prevent necrosis and perforation of the intestine. We report a case of PSV of the ileum in a 2-day-old female neonate whose clinical features and radiologic findings appeared to be meconium plug syndrome.
