Parapharyngeal Space Neoplasms
While primary neoplasms of the parapharyngeal space (PPS) are rare, secondary displacement or infiltration of this space, by pathology originating in neighboring spaces, is more commonly seen. An important role of imaging in the evaluation of PPS pathology, is to identify the space of origin. In combination with the imaging characteristics of the mass, this allows to reduce the differential diagnosis to a limited number of possibilities. This chapter reviews the key anatomical features of the PPS, and explains the imaging approach to mass lesions at this level.
