Primary bilateral maxillary sinus tuberculosis: a rare and an underdiagnosed entity

Tuberculosis (TB) is a great mimicker of innumerable diseases and is often overlooked causing diagnostic dilemmas, especially when it occurs at extrapulmonary sites. Primary TB of the paranasal sinuses is a rare event to occur with only a handful of cases documented in the world literature. Here, in this report, an unsuspected case of TB confined to bilateral maxillary sinus in a 50-year-old male is described which not only disguised as a case of chronic sinusitis but also led to a delay in the treatment of the patient.
