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

## TL;DR

This case report highlights how a dental imaging test helped detect a rare maxillary sinus cancer that initially appeared as a tooth-related issue.

## Contribution

The case emphasizes the role of intraoral periapical radiographs in early detection of maxillary sinus malignancies.

## Key findings

- Maxillary sinus malignancy was initially mistaken for a dental infection.
- Intraoral periapical radiograph played a key role in the early diagnosis of the malignancy.

## Abstract

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.
