Main differential diagnoses are osteosarcoma, chondrosarcoma,multilobulated tumor of bone (chondrosarcoma rodens) and squamous cell carcinoma.
The lymph node changes are suggestive for metastatic spread.
Final diagnosis would require sampling of the primary tumor for histology and fine needle aspiration of the lymph node.
The lesion is not resectable. The long term prognosis is poor.
However, staging and palliative treatment such as tumor irradiation could be considered depending on the owner’s wishes.
A large irregular soft tissue attenuating mass lesion is associated with the right temporal bone. The mass lesion presents stippled to amorphous mineralization. Extensive permeative osteolysis of the right temporal bone – including the zygomatic process and right tympanic bulla – with perforation of the cranial fossa is seen. The mass lesion presents marked extension into the cranial fossa, causing an extraaxial mass effect with distortion of the brain and a midline shift of the cerebral falx to the left. The mass lesion extends into the caudal part of the cranial fossa, the adjacent occipital bone presents permeative osteolysis as well. The medial extension is up to the level of the right orbital fissure and aggressive osteolysis of the right sphenoid bone is seen.
The right medial retropharyngeal lymph node is moderately enlarged with mildly irregular contrast enhancing.
