Orbital Tuberculosis with Intracranial Extension

Abstract

ABSTRACTWe report a case of orbital tuberculosis (OTB) with intracranial extension without active tuberculosis in the rest of the body organs or a history of tuberculosis infection. A 29-year-male patient presented with left-sided painful periorbital swelling with pus discharging sinus and visual impairment. Orbital computed tomography revealed contrast enhancing cystic mass lesion in the left orbit with erosion of the lateral and superior orbital wall with intracranial extension. After the failure of 3 weeks’ course of oral antibiotics, the patient underwent left lateral orbitotomy, pus was drained out, and granulation tissues were excised. Histopathological examination confirmed OTB. The patient had received antituberculous treatment. Periorbital swelling completely disappeared and vision improved over a period of 2 weeks. OTB should be considered in differential diagnosis of periorbital swelling especially when it does not respond to oral antibiotics.
