Summary:

Description
  • Radiopaedia case ID: 28165
  • Image ID: 6220116
  • Image stack position: 20/29
  • Plane projection: Coronal
  • Aux modality: C+ portal venous phase
  • Study description: CT Abdo/Pelvis following histology
  • Study findings: 2 cm lesion is seen in the mid-distal ileum, 50 to 60 cm from the ileocecal valve. This is associated with a very short segment intussusception. Adjacent mesenteric masses, the largest measuring 2.2 x 1.2 x 2.0 cm, shows mild desmoplastic reaction. No para-aortic, retroperitoneal and inguinal or thoracic lymphadenopathy. An enhancing lesion in hepatic segment 7 measures 1.9 x 1.5 x 1.3 cm. No further liver lesions are seen. Multiple small soft tissue nodules are seen from the gallbladder wall, likely polyps. No abnormality of the kidneys, spleen, pancreas, adrenals or bladder. No suspicious expansile or destructive osseous lesions. Conclusion: Ileal lesion, with adjacent desmoplastic mesenteric mass is concerning for a carcinoid tumor. Local mesenteric lymphadenopathy. Enhancing hepatic lesion may represent a carcinoid metastasis, with the differential being a hemangioma. This could be further evaluated with contrast enhanced ultrasound or quad-phase CT.
  • Modality: CT
  • System: Oncology
  • Findings: A well circumscribed right orbital mass demonstrating homogeneous contrast enhancement is seen. It displaces the medial rectus inferiorly and the superior rectus laterally. The optic nerve is displaced inferolaterally.
