Presentation
A palpable mass in the left parotid region.
Patient Data
The ultrasound image shows, within the parotid, an ovoid-shaped, hypoechoic, inhomogeneous lesion with well-defined margins and posterior acoustic enhancement.
Axial CT, pre- and post-intravenous contrast administration, confirms the presence of an ovoid-shape, well-defined, homogeneous lesion, with rapid enhancement located in the left parotid gland.
Case Discussion
Fine-needle aspiration (FNA) demonstrated a lymphomatous papillary cystadenoma, more commonly known as a Warthin tumor.
Warthin tumor is the most common tumor, after pleomorphic adenoma, of the parotid gland. It is more frequent in older patients, especially those with a smoking history, and is characterized by a lack of symptoms with a delay in the presentation. The prognosis is good.
