ABSTRACT
The increasing use of abdominal imaging has led to a growing incidence of traditionally uncommon pancreatic tumors. These rare tumors have specific imaging features whose knowledge may heighten confidence in characterization and may avoid unnecessary surgical procedures when imaging findings suggest a benign condition. Computed tomography (CT) is the modality with which rare pancreatic tumors are incidentally detected in the majority of cases. Magnetic resonance imaging (MRI) is often performed as a second line examination for further characterization. This review provides an update on CT and MRI findings of rare tumors of the pancreas.

Inflammatory bowel diseases (IBD) are associated with an increased risk of gastrointestinal cancers and more specifically in sites affected by chronic inflammation. However, patients with IBD have also an increased risk for developing a variety of extra-intestinal cancers. In this regard, hepatobiliary cancers, such as cholangiocarcinoma, are more frequently observed in IBD patients because of a high prevalence of primary sclerosing cholangitis, which is considered as a favoring condition. Extra-intestinal lymphomas, mostly non-Hodgkin lymphomas, and skin cancers are also observed with an increased incidence in IBD patients by comparison with that in patients without IBD. This review provides an update on demographics, risk factors and clinical features of extra-intestinal malignancies, including cholangiocarcinoma, hepatocellular carcinoma and lymphoma, that occur in patients with IBD along with a special emphasis on the multidetector row computed tomography and magnetic resonance imaging features of these uncommon conditions.

BACKGROUND AND AIMS: An association between Budd-Chiari syndrome (BCS) and celiac disease (CD) is uncommon. The aims of our study were to investigate the etiology of BCS and to search for a particular HLA Ag pattern among patients. PATIENTS AND METHODS: BCS diagnosis was based on Doppler ultrasound and CD diagnosis on duodenal biopsy, transglutaminase (TGAb) and gliadin antibodies (GAb). Patients were screened for prothrombotic disorders and seven had a PCR-SSO test for HLA genotypes. Patients were treated with anticoagulants and gluten-free diet. RESULTS: Nine patients were included; mean age 27 years (20-42); sex ratio (F/M) 2; mean follow-up duration 31 months (6-54). All patients had endoscopic and histological features of CD. GAb/TGAb were found in 78 % (n=7). Ag HLA found were HLA DQß1(*)02 (n=6) and DQß1(*)03 (n=3). Prothrombotic conditions identified were latent myeloproliferative disorder (n=1), protein C deficiency (n=1), probable factor V Leiden (n=1) and oral contraceptive use (n=1). No prothrombotic state could be identified in the five other patients. CONCLUSION: The BCS-CD association is relatively frequent in our country. Underlying prothrombotic conditions were absent in more than 50 % of cases, suggesting CD plays a role in the occurrence of thrombosis. HLA alleles found are strongly associated with CD, without any particular pattern for the BCS-CD association.

INTRODUCTION: In the absence of cadaveric grafts, a living donor liver transplant program was started in Algeria in February 2003. The aim of this study is to report the preliminary results. PATIENTS AND METHODS: From February 2003 to September 2004, eight adult-to-adult living related liver transplantations were performed. The donors were six women and two men of mean age of 25 years (range, 18 to 48 years). Right hepatectomy was performed in seven patients and left hepatectomy in one patient. The recipients were four women and four men of mean age 33 years (range, 16 to 56 years). Follow-up ranged from 1 month to 18 months (median 7 months). RESULTS: All donors survived the procedure. In the immediate postoperative period, two donors experienced complications. One donor underwent reoperation for hemorrhage and one suffered partial portal vein thrombosis, which was treated medically. The eight donors are alive at home without any late complications. One recipient died on postoperative day 43 due to sepsis. Among the seven other recipients, two experienced complications: one bilioma in relation to a biliary-intestinal fistula and one thrombosis of the splenic vein with a left portal embolus. At present the seven recipients are alive with normal liver function and without complications. CONCLUSION: Our results are comparable to other reports suggesting that adult-to-adult living related liver transplantation is feasible with no mortality and low morbidity in donors. However, it is important to develop a cadaveric liver transplant program.
