Ocular tuberculosis misdiagnosed as retinoblastoma: an interesting case

Intraocular tuberculosis masquerading as ocular tumor: A case report

Tuberculosis is one of the most common pediatric problems, especially in the developing world. In spite of that, intraocular tuberculosis is a rare disease that can easily be confused with other noninfectious processes, even in regions where tuberculosis is rampant. Diagnosis is difficult, yet it is very important to provide effective antituberculosis treatment and avoid potentially sight-losing interventions. We present a case of a 2-year-old child with a positive contact history of tuberculosis who presented with progressively worsening seizures and constitutional symptoms for 6 months. Brain computed tomography revealed right frontotemporal region conglomerated ring-enhancing lesions with central necrosis consistent with tuberculosis. On the same scan, a calcified right retinal lesion with a contrast-enhancing soft tissue component was identified. A chest radiograph and abdominal sonography showed evidence of disseminated tuberculosis. Subsequently, antituberculosis treatment was initiated, and the right retinal lesion improved, thus leading to the imaging diagnosis of right intraocular tuberculosis. Early and accurate diagnosis of retinal tuberculosis is of paramount importance in avoiding potentially catastrophic interventions. Neuroimaging is a useful, noninvasive method to consider this difficult diagnosis and also for follow-up.

Miliary tuberculosis presenting as bilateral pseudo-retinoblastoma

Objective: To describe an interesting case of miliary tuberculosis mimicking retinoblastoma. Method: A retrospective case report. Result: The twin brother of a known case of retinobastoma presented with headache. On fundus examination, multiple yellowish-white lesions were noted in both eyes. Magnetic resonance imaging of the brain showed multiple enhancing lesions. A diagnosis of miliary tuberculosis was made and anti-tubercular therapy was started. Conclusion: Ocular tuberculosis can mimic retinoblastoma and lead to diagnostic dilemma especially in cases with family history of retinoblastoma.
