Background:
Multiple choroidal granulomas are a rare presentation of tuberculosis. Choroidal granulomas in immunocompetent patients can pose difficulty in diagnosis as in most cases systemic examination may not reveal any evidence of tuberculosis. We report a case of bilateral multiple choroidal granulomas with systemic vasculitis-like features and disseminated tuberculosis in an immunocompetent patient without pulmonary involvement.
Findings:
A 26-year-old male Indian patient presented with bilateral blurred vision and systemic illness with vasculitis-like features. Examination revealed bilateral multiple choroidal granulomas and multisystem involvement without pulmonary involvement. Aqueous tap was positive for mycobacterium by polymerase chain reaction along with tissue biopsy leading to diagnosis. There was a good systemic and ocular response to anti-tubercular therapy with resolution of lesions.
Conclusions:
Our case emphasizes that, although uncommon, tuberculosis can involve multiple organs without pulmonary involvement and may mimic systemic vasculitis, it is not mandatory to have pulmonary findings for a confirmation of tuberculosis. Timely diagnosis with appropriate treatment can improve systemic and ocular disease.

Pulmonary Tuberculosis II
Here is a detailed explanation of its pathophysiology:
Transmission: The process begins when a person inhales droplet nuclei containing M. tuberculosis. These are typically released into the air when an individual with pulmonary or...
Pulmonary Tuberculosis I
Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.
