Salivary Gland Tumors: Evaluation with Two-Phase Helical CT

Abstract

The analysis of enhancement patterns by using two-phase helical CT will be helpful in the differential diagnosis of salivary gland tumors.

CT and Ultrasound Features of Basal Cell Adenoma of the Parotid Gland: A Report of 22 Cases with Pathologic Correlation

“…Pleomorphic adenoma shows little or no enhancement in the immediate postcontrast scan but strong enhancement in the delayed scan. 7,12,13 As opposed to pleomorphic adenoma, as shown in this study, BCA shows intense enhancement in the early phase, and this feature can be used to differentiate BCA from pleomorphic adenoma. 5,7 Warthin tumor is the second most common benign tumor of the parotid gland.…”

Solitary Fibrous Tumor of the Orbit: CT and MR Imaging Findings

“…Dual-phase helical CT can also be an alternative technique to dynamic CT for this purpose. 28,29 With the addition of delayed coronal scans, it can demonstrate a rough approximation of enhancing characteristics of the tumor. In this study, all 3 lesions examined with dual-phase CT demonstrated rapid, intense enhancement at early-phase axial scanning, followed by significant progressive washout of contrast material at late-phase axial and delayed-phase coronal scanning.…”

Myoepithelioma of the Parotid Gland: CT Imaging Findings

“…2 The use of CT for the assessment of parotid tumors is well established. Although much has been written on the CT appearance of the pleomorphic adenomas and Warthin tumors, [3][4][5][6][7][8][9] the detailed imaging features of MEs of the parotid gland have not been described previously in the English language literature. In this study, we describe the CT appearance of 10 histologically proven cases of MEs of the parotid gland.…”
