Title: CT and MRI Diagnosis of Cystic Masses of Neck
Abstract: Objective To investigate CT and MRI findings of cystic masses of the neck.Methods 44 cases with cystic neck lesionsincluding lymphadenopathy 12,abscesses2,nerve sheath tumors 3,salivary lesions 4,thyroglossal duct cysts 7,branchial cleft cysts 9,cystic hygromas 5,dermoidcyst 1 and laryngeal mucocele 1 comfired by operation-pathology were analysed.Results The cystic features of lesions could be showed on contrast-enhanced CT and MRI,cystic alteration in lymphadenopathy were due to necrosis and presented as the cystic wall enhanced and thickened.Salivary cystic lesions were variable.Congenital cystic masses usually appeared as a smooth,well-circumscribed mass,the cystic wall was thin and nonenhanced unless inflammation was present and most of them localized at the specificanatomic compartments.Thyroglossal duct cysts were mainly in the anterior midline portion of the neck at the level of the hyoid bone.Second branchial cleft was commonly in the posterior margin of the submandibular gland and lateral to the carotid space.Cystic hygroma was most commonly found in the posterior cervical space.Dermoid cyst presented in the floor of the mouth.Conclusion CT and MRI can provide essential informations in evaluating the nature and location of the cystic mass of neck,which is of significance for diagnosis and preoperative planning.
