Several conditions may present as nasal masses in pediatric age, including congenital and developmental disorders, inflammatory and infectious conditions, neoplastic and neoplastic-like lesions, and other miscellaneous disorders. A confident presurgical diagnosis can be challenging and imaging is often key in the management of these lesions. We provide a pictorial review of pediatric nasal masses and discuss a location-based approach to the diagnosis of these lesions on imaging studies. ⋯ Malignant tumors tend to be locally aggressive, demonstrating invasive features, bony erosion, intermediate signal on T2-weighted images, and restricted diffusion on diffusion-weighted imaging. In certain cases, a definite diagnosis can only be made histologically. Nonetheless, detailed characterization of the lesion is crucial prior to invasive procedures in order to avoid complications.

Fibrosing inflammatory pseudotumor (FIP) of the nasopharynx is a rare nonneoplastic inflammatory lesion that is frequently mistaken for malignancy or infection. It is often misdiagnosed by radiologists as nasopharyngeal carcinoma or lymphoma, resulting in multiple biopsies and delays in diagnosis. The purpose is to understand trends in clinical presentation, imaging findings, treatment modalities, and patient outcomes of nasopharyngeal FIP. ⋯ Nasopharyngeal FIP is a histological diagnosis of exclusion that presents with facial pain and, often, cranial neuropathies. Relatively low T2-weighted MRI signal should inform the interpreting neuroradiologist to include FIP as a differential consideration for both the ordering provider and pathologist. Corticosteroid therapy is the most frequently employed therapy and results in partial or complete response in most patients. Radiation therapy and anti-inflammatory medications have also been reported to have potential therapeutic roles.
