  • Radiopaedia case ID: 59258
  • Image ID: 37359525
  • Study findings: Image 1: Right internal carotid artery (red circle) with circumferential tumor. Image 2: Tumor infiltration of the medial pterygoid muscle (blue arrows). Image 3: Altered signal in the right side of the clivus (blue arrows) compared to the normal left side (red arrow). Image 4: Tumor in the right side of the cavernous sinus (blue arrows) surrounding the C4 segment of the ICA and exerting mass effect on the inferior temporal lobe. Image 5: Tumor (blue arrows) extending into and expanding the right buccinator space.
  • Modality: Annotated image
  • System: Head & Neck
  • Findings: Huge right sided nasopharyngeal mass with bulk dimensions of 5.6 x 4.3 cm which extends cranially to invade the right side of the cavernous sinus surrounding the C4 segment of the ICA. The tumor extends into the right carotid space with tumor circumferentially around the right internal carotid artery and posterior extension towards the right hypoglossal canal. Tumor extends laterally to infiltrate into the right medial pterygoid muscle and posteriorly into the right longus capitis muscle in the prevertebral space. Laterally the tumor infiltrates and expands the right buccinator space. Signal change in the right side of the clivus suggests marrow infiltration. Fluid in the mastoids and maxillary sinuses, the former in keeping with Eustachian tube obstruction. Large volume cervical lymphadenopathy with a 6.1 cm right submandibular and bilateral internal jugular chain nodes (levels II and III) upto 3.5 cm.
