Two-Phase Helical Computed Tomography Study of Salivary Gland Warthin Tumors: A Radiologic Findings and Surgical Applications

摘要: Objectives The goal of this study was to define the radiologic characteristics two-phase computed tomography (CT) salivary gland Warthin tumors and compare them pleomorphic adenomas. We also aimed provide a foundation for selecting surgical method on basis findings. Methods prospectively enrolled 116 patients with parotid tumors, who underwent CT preoperatively. Early delayed phase scans were obtained, scanning delays 30 120 seconds, respectively. attenuation changes enhancement patterns analyzed. In cases when decreased, we presumed tumor preoperatively performed extracapsular dissection. When increased, superficial parotidectomy tumors. analyzed operation times, incision sizes, complications, recurrence rates. Results Attenuation decreased from early scans. ratio numbers in significantly different other diagnosed sensitivity 96.1% specificity 97% using CT. mean time 38 minutes size 36.2 mm However, average 122 91.8 (P Conclusion Salivary has distinct pattern contrast CT, which can guide treatment decisions. preoperative diagnosis made dissection possible instead parotidectomy.
