Abstract:
Objective To evaluate CT manifestations and its clinical significance of the laryngopharyngeal carcinoma.Methods CT findings of 18 cases with laryngopharyngeal carcinoma proved by surgery and pathology were analysed.Results Of 18 cases,11 cases were in the piriform fossa,5 cases were in the postcricoid region and 2 cases were in the posterior wall of laryngeal pharynx.The tumor showed isodense or mixed density and slightly enhancement.It was the characteristic feature of the laryngopharyngeal carcinoma that the tumor pushed the annular and arytenoid cartilage displacement anteriorly,the thyroarytenoid gap and cricothyroid joint were widened.Other indirect findings included invasion of the larynx and esophageal ostium,destruction of laryngeal cartilage and metastasis of lymph node of neck.Conclusion CT can reliably exhibit the location,size and extent of the tumors and metastasis of lymph node of neck.It is useful in working out the thearapeutic program and evaluating prognoses.
