[The relationship between pathology and imaging overview in pediatric nasal tumors]

Objective:To study the clinical features and nasal image of children with nasal tumors.Method:The samples of 40 cases of pediatric nasal tumors, which were diagnosed based on pathology, were collected. Clinical features, pathological histology and imaging characteristics were also summarized.Result:There were 23 cases of benign tumors and 17 cases of malignancy. The most common benign tumors were angiofibroma (7 cases), capillary hemangioma (4 cases) and ossifying fibroma (4 cases), while the most common malignant tumors were lymphoma (10 cases) and embryonal rhabdomyosarcoma (3 cases). In all cases, 10 tumors arose from sinus, 7 tumors limited in the nasal cavity or nasal vestibule, 8 tumors located in sinonasal, 10 tumors are originated from nasopharyngeal area and (or) postnaris, 3 cases located in the lateral nasal, 2 cases located in the nasal septum. CT or MRI found that 13 cases showed bone destruction, 5 cases showed bone absorption, 14 cases involvement of adjacent structure, 6 cases with cervical lymph node enlargement.Conclusion:The common nasal tumors in children include lymphoma, angiofibroma, capillary hemangioma, ossifying fibroma and embryonal rhabdomyosarcoma. Clinical manifestations of pediatric nasal tumors were atypical, the diagnosis mainly dependent on pathology and imaging examination. CT and MRI examination can well depict the site of tumors, the bone change of the around situation and the encroachment of the tumor accurately, and may play an important role in clinical diagnosis and staging of the tumors, constituting the treatment plan and prognosis evaluation.
