Background: Nasal and paranasal sinus masses can arise from a wide range of conditions, both benign and malignant, as well as congenital or acquired. Diagnosing these masses is often challenging, requiring a combination of nasal endoscopy, imaging studies, and histopathological analysis. Initial imaging frequently involves computed tomography or cone beam computed tomography (CBCT) to evaluate the bony anatomy of the nasal cavity and surrounding sinuses, while magnetic resonance imaging (MRI) is typically used for detailed assessment of soft tissues and to aid in differential diagnosis when the findings are inconclusive. Methods: This review examines nasal masses evaluated using CT, CBCT, and MRI, highlighting key imaging features that may assist in differential diagnosis. Results: For non-neoplastic lesions, examples include conditions such as rhinoliths, inverted mesiodens, and septal mucoceles. Benign and borderline tumors discussed encompass lobular capillary hemangioma, inverted papilloma, septal osteoma, chondromesenchymal hamartoma, hemangioma, hemangiopericytoma, antrochoanal polyp, sinonasal angiofibroma, ossifying fibroma, and lipoma. Malignant tumors addressed in this review include adenocarcinoma, esthesioneuroblastoma, non-Hodgkin lymphoma, melanoma, and sarcoma. Conclusions: Diagnosing nasal lesions represent a significant challenge for otolaryngologists. Imaging characteristics of nasal masses play a crucial role in narrowing down differential diagnoses before surgery. However, nasal endoscopy combined with biopsy remains the definitive diagnostic approach.

Abstract

Background: Nasal and paranasal sinus masses can arise from a wide range of conditions, both benign and malignant, as well as congenital or acquired. Diagnosing these masses is often challenging, requiring a combination of nasal endoscopy, imaging studies, and histopathological analysis. Initial imaging frequently involves computed tomography or cone beam computed tomography (CBCT) to evaluate the bony anatomy of the nasal cavity and surrounding sinuses, while magnetic resonance imaging (MRI) is typically used for detailed assessment of soft tissues and to aid in differential diagnosis when the findings are inconclusive. Methods: This review examines nasal masses evaluated using CT, CBCT, and MRI, highlighting key imaging features that may assist in differential diagnosis. Results: For non-neoplastic lesions, examples include conditions such as rhinoliths, inverted mesiodens, and septal mucoceles. Benign and borderline tumors discussed encompass lobular capillary hemangioma, inverted papilloma, septal osteoma, chondromesenchymal hamartoma, hemangioma, hemangiopericytoma, antrochoanal polyp, sinonasal angiofibroma, ossifying fibroma, and lipoma. Malignant tumors addressed in this review include adenocarcinoma, esthesioneuroblastoma, non-Hodgkin lymphoma, melanoma, and sarcoma. Conclusions: Diagnosing nasal lesions represent a significant challenge for otolaryngologists. Imaging characteristics of nasal masses play a crucial role in narrowing down differential diagnoses before surgery. However, nasal endoscopy combined with biopsy remains the definitive diagnostic approach.
