60 year old male with right squamous cell carcinoma of the tongue. Volume CT scan of the neck with contrast. 2.5 mm coronal image shows a large confluent indistinctly marginated soft tissue mass along the right side of the neck, extending from the angle of the mandible inferiorly to the level of the thyroid cartilage, approximately 7.8 cm CC x 5.3 cm AP x 4.5 cm transverse. Laterally, the mass infiltrates and enlarges the sternocleidomastoid muscle. Medially, the mass extends to the level of the hypopharynx and completely encases the internal and external carotid artery on the right without appreciable narrowing of those vessels. The mass is predominately isodense to muscle with a 1 cm low attenuation component inferiorly consistent with necrosis or haemorrhage. The confluent lymphadenopathy may be seen with lymphoma and metastatic nasopharyngeal carcinoma. | |
