Benign lymphoepithelial cyst of parotid gland without human immunodeficiency virus infection: A case report

Figure 2 Neck computed tomography. A: Plain computed tomography scan. A round cystic lesion was seen in the left parotid gland, with a maximum cross-sectional area of about 2.3 cm × 2.2 cm, uneven density, small patches with slightly high-density shadow, and clear boundary; B: Arterial phase. On enhanced scanning, the cyst wall was slightly enhanced in the arterial phase, but no obvious enhancement was observed in the cyst; C: Venous phase. The enhancement degree in the venous phase was similar to that in the arterial phase (orange arrows).
