Abstract

Inflammatory pseudotumors are benign soft tissue tumors that in rare cases can also manifest in multiple organs. We report here on the radiologic findings of a case of inflammatory pseudotomor mimicking malignant lymphoma involving the liver, pancreas, common bile duct, kidney, renal pelvis and lymph nodes of the abdomen and mediastinum, as well as the bronchus in an adult.

  Fig. 1 A 67-year-old man presenting with jaundice and poor oral intake. A. Ultrasonography showing hyperechoic thickening in the distal CBD with proximal biliary tree dilatation. B. Ultrasonography in the axial plane at the S6 segment region demonstrating a small oval hypoechoic mass. C. Axial CT image shows the swelling of pancreatic head (arrows) and thickening of the left renal pelvis and upper ureter (arrowhead). D. Coronal reformatted CT image showing thickening and stenosis of the distal common bile duct (arrow) and dilatation of proximal biliary tree. E. Coronal reformatted CT image showing an ill-defined, low-attenuation mass lesions (arrow) in the left kidney. F. Axial CT image showing multiple lymph node enlargement with homogeneous enhancement in both the perihilar and mediastinal area (arrows), with LUL bronchial wall thickening (arrowhead). G. Histologic specimen obtained by core needle biopsy from the hepatic lesion. Photomicrograph of the histologic preparation (hematoxylin-eosin, original magnification × 400) showing a broad fibro-inflammatory lesion, composed of dense lymphoplasma cell infiltration and fibrosis. H. Follow-up CT scan images obtained after 20 days later, showing the improvement of thickening of the distal CBD (arrow), left upper ureter, and bronchus, and decreased in size of the ill-defined mass in the left kidney and pancreas head (not shown).
