  ABSTRACT: To evaluate magnetic resonance (MR) imaging morphologic- and signal intensity abnormalities of deep infiltrating endometriosis (DIE) of the bowel wall and to assess its value in predicting depth and extent of bowel wall infiltration. This single-center study was performed in a tertiary referral center for endometriosis. All patients (n = 28) who underwent segmental bowel resection (2004-2010) were retrospectively studied. MR images were analyzed by two experienced readers independently (number of lesions, location, size, signal intensity, and depth of bowel wall infiltration) and this was correlated with histopathology. The sensitivity, specificity, positive and negative predictive values, and accuracy for diagnosis of endometriosis infiltrating the muscular layer of the bowel were 100%, 75%, 96%, 100%, and 96%, respectively. The inter-rater agreement was 0.84. "Fan shaped" configurations with hypointensity on T2- and T1-weighted imaging were characteristic for thickening of indigenous smooth muscle and smooth muscle hyperplasia at histopathology, as a consequence of infiltration by endometriosis. Thickening of the (sub)mucosa corresponded to edema with or without infiltration of endometriosis. MR imaging at 1.5 Tesla is useful to predict muscular infiltration of the bowel in endometriosis, whereas it is of limited value in diagnosis of (sub)mucosal infiltration.

  ABSTRACT: Gallstone ileus is an uncommon cause of small bowel obstruction, affecting mainly elderly patients. We report a case of gallstone ileus in an 88-year old female patient. The correlation between computed tomography, double-balloon enteroscopy and intra-operative findings is discussed, as well as treatment strategies.

  ABSTRACT: Bile duct injury is a common complication after hepatobiliary surgery, but may also occur in post-traumatic patients. Early diagnosis and treatment are crucial to prevent long-term morbidity. We present a case with a liver laceration and biliary leakage following a gunshot incident, which was demonstrated on MR cholangiography using gadoxetic-acid-disodium (Primovist). This liver-specific contrast agent provides excellent demonstration of bile leakage as well as the intrahepatic bile tree, being a safe, non-invasive and accurate technique for contrast-enhanced cholangiography without use of ionizing radiation.
