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\u2010based approach to the diagnosis of these lesions on imaging studies. Acquaintance with the most common pathologies and awareness for its characteristic imaging features can aid the physician in the differential diagnosis. Location and extension of the lesion can be particularly helpful. Midline masses raise suspicion for developmental nasal midline lesions, including frontoethmoidal cephalocele, dermoid\/epidermoid cyst, and neuroglial heterotopia. In case of trauma, nasal septum hematoma\/abscess should be considered. Developmental or odontogenic cystic lesions and osseous neoplasms and neoplasm\u2010like lesions can originate from the maxilla and palate. Although most nasal tumors show overlapping imaging characteristics, some have suggestive features, such as nasopharyngeal angiofibroma and esthesioneuroblastoma. Malignant tumors tend to be locally aggressive, demonstrating invasive features, bony erosion, intermediate signal on T2\u2010weighted images, and restricted diffusion on diffusion\u2010weighted 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.<\/jats:p>","DOI":"10.1111\/jon.12942","type":"journal-article","created":{"date-parts":[[2021,10,27]],"date-time":"2021-10-27T15:53:32Z","timestamp":1635350012000},"page":"230-244","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Imaging
