Description
  • Radiopaedia case ID: 31167
  • Image ID: 8410511
  • Image stack position: 78/92
  • Plane projection: Axial
  • Aux modality: bone window
  • Modality: CT

  • Findings: Deep to the right SCM muscle sternocleidomastoid is a relatively low density ?cystic mass, separate to the parotid gland and carotid sheaths, (20 x 25 x 17 mm) ~20 Hounsfield units. The mass is well circumscribed and superiorly appear to be a number of branching or tubular structures of similar density, which is atypical for a branchial cleft cyst. No fat stranding seen around the mass. A couple of lobulated lesions,  of somewhat lower density (-20 HU) are seen between the anterior border of SCM and the overlying skin.
