Nasopharyngeal inflammatory pseudotumor: Multimodality imaging characterization

Abstract Nasopharyngeal inflammatory pseudotumors are very rare idiopathic infiltrative nasopharyngeal/skull base mass lesions. Imaging findings mimic the local infiltrative and destructive features of nasopharyngeal carcinoma, lymphoma and minor salivary gland tumors however without nodal dissemina...

Description
Summary:Abstract Nasopharyngeal inflammatory pseudotumors are very rare idiopathic infiltrative nasopharyngeal/skull base mass lesions. Imaging findings mimic the local infiltrative and destructive features of nasopharyngeal carcinoma, lymphoma and minor salivary gland tumors however without nodal dissemination. Apparent Diffusion Coefficient determination may aid the discrimination of benign from malignant nasopharyngeal lesions. Confident nasopharyngeal biopsy is required for effective therapeutic management. Failure to recognize this rare inflammatory process contributes to protracted symptomatology including evolving cranial neuropathy.
