Unravelling the mystery of maxillary sinus malignancy initiated with periapical radiograph: A case report.

Maxillary sinus malignancies, rare but often mimic dental infections, can present as asymptomatic growth until perforation. Symptoms mimic inflammatory sinus lesions, with many patients seeking dental treatment first. Clinical presentation depends on which walls of sinus is the affected. Hence, we report the diagnostic journey of a patient, with odontogenic symptoms, ultimately diagnosed as malignancy of the maxillary sinus. The diagnosis initiated from an intraoral periapical radiograph (IOPAR) in this case emphasizes the significance of imaging in early detection of maxillary sinus malignancies, masquerading as dental infection.
