Abstract:
Objective To investigate the imaging findings of craniocervical adenoid cystic carcinoma(ACC)with invading adjacent tissues,neural foramen and tube.Methods The CT and MR imaging features of 33 cases of craniocervical ACC with invading adja-cent tissues,neural foramen and tube of the basis cranii were analyzed retrospectively and compared with surgical and pathological results.Results Among 33 cases of ACC,17 cases were located in the nasal cavity,sinuses and nasopharynx(including 3 cases of recur-rence after surgery),8 cases in salivary gland,5 cases in lacrimal gland and lacrimal sac,and 3 cases in external auditory canal.Tumors invaded and destroyed adjacent muscle bundles,spaces,nasal cavity,sinuses,and bone walls in 16 cases,invaded pterygopala-tine fossa in 9 cases,pterygoid canal in 7 cases,foramen rotundum in 6 cases,foramen ovale in 5 cases,nasolacrimal duct in 3 cases,foramina stylomastoideum in 2 cases and external auditory canal in 3 cases(a total of 35 foramen and tubes).When the tumor inva-ded the adjacent muscle bundles,spaces,nasal cavity,sinuses and basis cranii,CT or MR showed the thickening of the surrounding tissues,with the density/signal abnormalities and obvious enhancement.When the tumor invaded the adjacent bone,cartilage,neural foramen and tube,CT displayed the thickening,thinning,or loss of the bone wall,as well as the enlargement of neural foramen and tube,wall thickening,and bone destruction.Conclusion CT and MR can show the imaging features of multiple small vesicles and ethmoid structures in the craniocervical ACC,as well as the invasion of adjacent tissues and the destruction of basis cranii,maxillofa-cial nerve foramen and tube,which are of great significance for the imaging diagnosis and surgical treatment of craniocervical ACC.
