Summary:

Description
  • Radiopaedia case ID: 57437
  • Image ID: 34778811
  • Image stack position: 16/28
  • Plane projection: Axial
  • Aux modality: C+ portal venous phase
  • Modality: CT
  • System: Head & Neck
  • Findings: A well-defined contour mass is seen filling the left masticator space with medial displacement of the left parapharyngeal fat and posterior displacement of the carotid sheath. Lateral extension into the left infratemporal fossa. Associated destruction of the left pterygoid plates, as well as the posterior and medial boundaries of the left maxillary sinus. Infiltration and destruction of the bony boundaries of the sphenoid and left posterior ethmoid air cells. Superiorly the lesion causes the destruction of the related sphenoid and squamous parts of the left temporal bone with subsequent intra-cranial extension into the middle cranial fossa and upward and posterior displacement of the related temporal lobe. No underlying brain edema. The sellar component of the lesion is seen displacing the pituitary gland superiorly and encasing the lacerum and cavernous segments of the left internal carotid artery.  A more posterior component is seen extending also into the posterior cranial fossa, filling the left cerebellopontine angle and abutting the related aspect of the pons. Bony destruction of the left lateral orbital wall (the greater wing of the sphenoid) is also noted with the abutment of the left lateral rectus muscle.
