Abstract:
An 8-year-old girl presented with left leukocoria, prompting an evaluation that revealed bilateral intraocular masses, including a right upper nasal choroidal lesion and a large left heterogeneous mass with exudative detachment. Imaging and systemic assessment uncovered multiple intracranial lesions, miliary lung lesion, a facial lesion, and a right tibial lesion. A strongly positive tuberculin test and a history of close contact with a tuberculosis (TB) patient led to the diagnosis of disseminated TB. Treatment with anti-tuberculosis therapy and systemic steroids initially resulted in improvement, including regression of the ocular tuberculomas and enhanced visual acuity. However, the patient developed severe headache due to non-communicating obstructive hydrocephalus, necessitating surgical intervention. Despite intensive care, the patient ultimately succumbed to the condition. This case highlights that ocular TB lesions can mimic intraocular tumors and underscores the importance of comprehensive evaluation, including multimodal imaging and systemic work-up, for early diagnosis and management of disseminated TB.

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.
