Orbital tuberculosis - an interesting case report.

Orbital tuberculosis is a relatively uncommon disease. A 17-year-old male presented with an intraorbital lesion suggestive of orbital pseudotumor. Initial clinical response to oral corticosteroid therapy was followed by development of a mass lesion in the left orbit, which led to the formation of a discharging sinus in relation to the orbit and simultaneous cervical lymphadenitis. Diagnosis of tuberculosis was confirmed and patient responded to four drug antitubercular therapy. The patient had an unusual presentation and the disease course was altered by corticosteroid therapy. This case highlights the need for keeping a high index of suspicion for tuberculosis, especially in patients on immunosuppressive therapy.
