An interesting case of orbital tuberculosis with intracranial extension

Abstract

Tuberculosis (TB) is a chronic airborne infectious disease caused by Mycobacterium tuberculosis and is one of the causes of morbidity and mortality in the underdeveloped nations. TB most commonly involves the lungs, but it can affect nearly any tissue in the body, including the orbit. Orbital TB is a rare manifestation even in endemic countries and mostly occurs as part of systemic involvement secondary to pulmonary disease. Exclusive extrapulmonary involvement of the orbit with intracranial extension is very rare; diagnostic dilemma, unique management, and the outcome make our case interesting and worthy of reporting.
