A rare case of orbital tuberculosis with cold abscess and frontal bone lesion.

Tuberculosis is a multisystem infectious disease caused by Mycobacterium tuberculosis and a leading infectious cause of morbidity and mortality worldwide. Orbital tuberculosis is a rare form of extra pulmonary tuberculosis, even in endemic areas. It may involve the soft tissue, lacrymal gland, periosteum, or bones of the orbital wall and can extend to adjacent paranasal sinuses or intracranial cavities. The delay in diagnosis can be due to the fact that the clinical signs simulate any inflammatory disease. The diagnosis is usually based on tissue examination in histopathological evidence presenting as granulomatous lesion or presence of acid fast bacilli (AFB). The long term anti tuberculosis therapy is the effective treatment. Here we present the case of orbital tuberculosis on a young man operated in our department and who had a good outcome under anti tuberculosis drugs for 12 months.
