A 16-year-old female patient with PA in the right submandibular gland with a diameter of 1.9 cm. The lesion was a well-defined, homogeneous low-density, and round nodule ((a), white arrow). Slight enhancement was observed on contrast-enhanced CT ((b), white arrow). The PA was confirmed by HE staining (c). A 21-year-old female with PA in the right submandibular gland with a length of 2.6 cm in the long axis (d–f). The mass showed a well-defined, relatively homogeneous, slightly low-density, and round mass ((d), white arrow). Mild to moderate enhancement was observed on contrast-enhanced CT ((e), white arrow).
