Oncocytoma of the parotid gland is a rare salivary gland tumor. The prognosis is usually favorable if the tumor can be removed surgically. We reported 2 cases of parotid gland oncocytoma and discussed the usefulness of radiographic findings in diagnosis. CT scans of the neck showed a well-defined homogenous parotid mass. MRI scans demonstrated a well circumscribed and lobulated mass of homogeneous intermediate signal intensity on T1-weighted images and hyperintensity on T2-images. The tumor was characterized by early enhancement following contrast injection. The tumor exhibited intense uptake and prolonged retention of Tc-99 m pertechnetate. Radiographic study revealed no specific imaging characteristics of oncocytoma. This tumor was similar in imaging characteristics to Warthin's tumor. Thus, close attention to the differential diagnosis is important when imaging is used as a diagnostic technique.
