The sensitivity and specificity of high-resolution imaging in evaluating perineural spread of adenoid cystic carcinoma to the skull base

摘要: Objective To evaluate the sensitivity and specificity of computed tomography (CT) magnetic resonance imaging (MRI) in detecting perineural spread (PNS) adenoid cystic carcinoma head neck to skull base. Design Adenoid frequently exhibits PNS across Failure detect before treatment can have significant negative consequences on planning outcome therapy. High-resolution CT, MRI, or both are used presence PNS; however, their accuracy involvement has not yet been determined. Patients Twenty-six consecutive patients with carcinoma, who were treated cranial base resection, included this study. The surgical resection specimens all thoroughly examined by 1 pathologist for along nerves named branches. A total 38 examined, was defined as tumor endoneural space. results preoperative studies (CT and/or MRI) then reviewed retrospectively radiologist, unaware pathology report. Radiological evidence considered be present if showed thickening (regardless enhancement), contrast enhancement size), widening bony foramina canals. Results Histopathologic 25 (66%) nerves. CT 88% 89%, respectively. Magnetic had a higher (100%) (85%). Conclusions Perineural is frequent occurrence neck. than skull.
