Acute Intestinal Anisakiasis: Ct Findings
(Univ Catholique Louvain-ucl, 2012) Ozcan, H. N.; Avcu, S.; Pauwels, W.; Mortele, K. J.; De Backer, A. J.
Small bowel anisakiasis is a relatively uncommon disease that results from consumption of raw or insufficiently pickled, salted, smoked, or cooked wild marine fish infected with Anisakis larvae. We report a case of intestinal anisakiasis in a 63-year-old woman presenting with acute onset of abdominal complaints one day after ingestion of raw wild-caught herring from the Northsea. Computed tomography (CT) scanning demonstrated thickening of the distal small bowel wall, mucosa with hyperenhancement, mural stratification, fluid accumulation within dilated small-bowel loops and hyperemia of mesenteric vessels. In patients with a recent history of eating raw marine fish presenting with acute onset of abdominal complaints and CT features of acute small bowel inflammation the possibility of anisakiasis should be considered in the differential diagnosis of acute abdominal syndromes.

Introduction We report the CT and MR findings in a 30-year-old man with extraskeletal Ewing sarcoma (EES) involving the left neural foramen at L5-S1 level. Materials and methods The patient was evaluated with preoperative lumbosacral CT and MR imaging and postoperative lumbosacral MR imaging. Results The lesion was hyperdense on CT, isointense on T1- and T2-weighted MR images, and enhanced homogeneously after intravenous gadolinium injection. With these CT and MR findings, surgery was performed with a presumptive diagnosis of nerve sheath tumor, but the histopathological examination revealed EES. Chemotherapy and radiotherapy were planned postoperatively. Conclusion This case illustrates that even in benign looking lesions in a neuroforamen one can never exclude malignancy, and this is even more true in a population of young adults.
