The deep and diffuse distribution of salivary glands in the soft tissue of the head and neck region is one common limitation to the early diagnosis of Pleomorphic Adenoma (PA) from those glands. The limits of this type of lesion cannot be established by clinical exam only. Magnetic resonance imaging (MRI) has being playing an important role in the diagnosis of the AP. This image modality provides high resolution of soft tissue with no ionizing radiation. The majority of the studies have been shown it superiority for this purpose. The aim of this study was to review the literature and to discuss the importance, advantages, and disadvantages of the different imaging techniques for the diagnosis and treatment plan of the most prevalent neoplasm of salivary glands - Pleomorphic Adenoma. Reports of clinical cases will illustrate the most important reasons that justify the superiority of MRI for the above-mentioned investigation.
