Application Of MSCT In The Diagnosis Of Cervical Cystic Lesion

Objective: To evaluate the performance of various types of CT cystic lesions of the neck,to assess the diagnostic value of MSCT cystic lesions of the neck, in order to improvediagnostic accuracy.Methods: A hospital in September2012-March201566cases of cervical cystic lesions,38males and28females, aged3to77years, mean37years old.66patients were confirmedby neck CT, continuous availability of CT images. Thyroglossal duct cyst which6cases,14cases of lymphangioma, ganglion cyst in2cases,18cases of lymphoepithelial cyst, branchialcleft cyst14cases, six cases of epiglottic cysts, epidermoid cyst six cases. Cystic lesions onthe neck by age, gender, side of gender, disease constituent ratio, shape, size, density cysts,wall enhancement, such as separate aspects of CT findings were compared against variousdiseases, mainly x2test capsule density contrast within variance test was used for statisticalanalysis.Results: neck cystic lesions including thyroglossal cyst, lymphangioma lymphoepithelialcysts, branchial cleft cyst, epiglottic cysts, epidermoid cyst, ganglion cyst. Thyroglossal cystlocated mainly in the midline of the neck area, the level of the thyroid cartilage;morphologically common in oval; maximum diameter smaller than most3cm, located inindividual cases thyroglossal membrane level, may rush back before the epiglottis gap; lowdensity intracapsular with lymphoepithelial cyst, epiglottis cyst capsule density weresignificantly different; the wall is generally not enhanced when accompanied by infection, canbe mild enhancement; no separation. Lymphangioma more in the parapharyngeal space, morerelationships with adjacent muscle, platysma exist and the visible part of the internal carotidartery lesions surrounded;more common in round or oval; maximum diameter of how to3cm;intracapsular density of about20-30HU,there are significant differences withlymphoepithelial cyst and epiglottic cyst capsule density; more than a reinforced wall, varyingdegrees; in some cases visible separation. Lymphoepithelial cyst elliptical common; much in diameter3cm,form large; intracapsular high value ingredients CT cystic lesions in the neck, inaddition to branchial cleft cyst, the sick and the other four are present in statisticallysignificant differences; enhanced scan common wall edge enhancement; no separate, showeda single bag, single room; occurred in the sternocleidomastoid around and inside of themajority, the corresponding parts of the sternocleidomastoid pressure; branchial cleft cystlocated inside or medial sternocleidomastoid a bit before the submandibular glandanterolateral medial carotid sheath; the more common form of oval; this group of patients, nosignificant differences in maximum diameter, the size of both; intracapsular density Otherlesions was statistically no difference, only the epiglottis cyst capsule density and statisticallysignificant (p<0.05); more than a reinforced wall, no separation. Epiglottic cyst specificlocation, situated in front gap epiglottis epiglottis lingual; circular/oval common, diameter>3cm, intracapsular mean low density, enhanced scan showed no reinforced wall, a few haveseparated. Epidermoid cyst found in multiple sites, and more in this group of patients in thesubmandibular, and more irregular shape, can be multiple or showed multiple cystic, so themaximum is less than the diameter of each capsule more3cm,capsule density is uniform,wallAfter enhancements are strengthened, this group of patients with epidermoid cyst adjacentsternocleidomastoid relationship does not exist.Conclusion:(1) Forms a large, located next to the more common cystic lesionssternocleidomastoid tumor and lymph lymphatic cyst epithelium, which is high CT value, noseparate common in lymphoepithelial cyst growth gap along the neck more foundlymphangiomaï¼›(2) occurs in cystic lesions of the midline area, close to the more common andthe hyoid bone in thyroglossal cyst, located epiglottis epiglottis tongue or neck before the gapis more common in the epiglottis cyst, shape, wall strengthening in the second degreeidentification of those meaningful.(3) no fixed anatomical site, uneven capsule CT value,may have separated, polycystic, have enhanced the partition wall and cystic lesions, commonin epidermoid cyst.
