Abstract Background Low-phospholipid associated cholelithiasis (LPAC) remains an under-diagnosed condition. It can be revealed by complications such as acute cholecystitis, acute angiocholitis and acute pancreatitis. We report a case of acute pancreatitis secondary to LPAC syndrome. Case presentation A 58-year-old woman was hospitalized for recurrent biliary-type abdominal pain after cholecystectomies. The diagnosis of acute biliary pancreatitis revealing a low-phospholipid associated cholelithiasis syndrome was retained after explorations. An abdominal ultrasound performed by an expert radiologist allowed us to confirm the diagnosis of LPAC syndrome, showing a comet tail image along the intrahepatic bile ducts. Ursodeoxycholic acid was started without waiting for the result of the ABCB4 mutation. The outcome was spectacular with complete disappearance of the symptoms after the first week. Conclusion Expert ultrasound remains the key examination for the confirmation of the diagnosis of a low-phospholipid associated cholelithiasis syndrome. It should be requested at the slightest warning signs such as a young age less than 40 years and recurrence of biliary symptoms after cholecystectomy.

Abstract Background Acute cellular rejection beyond the 6th month posttransplant is an uncommon complication after liver transplantation. The inadequate immunosuppression (IS) remains the main risk factor. We report a case of acute cellular rejection after a switch to everolimus monotherapy at 11 months following liver transplantation. Case presentation This was a 69-year-old man who underwent liver transplantation after hepatocellular carcinoma. The initial immunosuppression was a combination of three immunosuppressive drugs (corticosteroids + tacrolimus + mycophenolate mofetil). The corticosteroid therapy was stopped at the 4th month posttransplant. Serious side effects of the immunosuppressive drugs (agranulocytosis and renal dysfunction), which occurred 4 months after transplantation, required a reduction and then a discontinuation of tacrolimus and mycophenolate mofetil. Everolimus was introduced as a replacement. The patient was consulted at 11 months after liver transplantation, 1 month after stopping the two immunosuppressive drugs, for liver function test abnormalities such as cytolysis and anicteric cholestasis. A moderate late acute cellular rejection was confirmed by a liver biopsy. A satisfactory biological evolution was observed following corticosteroid boluses and optimization of basic immunosuppressive drugs. Conclusion Late acute cellular rejection remains an uncommon complication, observed mostly in the first year after liver transplantation. The main risk factor is usually the decrease of immunosuppression.
