Abstract Objectives: To describe the uncommon radiological findings in the nasopharynx and paranasal sinuses in 2 patients who were diagnosed with nasopharyngeal myiasis after a presumptive diagnosis of complicated sinusitis. Methods: Two patients were diagnosed with complicated sinus disease after they were admitted to the ENT service with marked periorbital eritema and edema, mucopurulent and foul nasal discharge. As part of a preoperative work a paranasal sinuses CT was ordered showing edema of the maxillary sinus mucosa along with areas of severe edema of the nasopharynx mucosa with multiple areas of defect and radiolucency. Results: The patients were taken to surgery and much to the surgeons surprise aside from the findings of the mucuporulent discharge and the mucositis, multiples larvae were retrieved from the patients maxillary sinuses and the nasopharynx explaining the strange and scattered areas of radiolucency distributed throughout the nasopharynx mucosa. Conclusion: Although rare in developed countries, nasal myiasis can be seen in patients with poor hygienic conditions. Patients with complicated sinusitis show in their CT multiple changes due to their infection but a pattern of scattered areas of defect, like the ones described with these 2 patients with nasal myiasis is quite rare.
