To explore the diagnostic challenges of miliary tuberculosis in non-endemic areas and introduce the seed of a potential new approach. 

Mycobacterium tuberculosis's diverse clinical presentation makes it a compelling mimicker of various diseases. This organism is challenging to isolate, exhibits slow growth, and can affect any organ system, including the central nervous system, leading to a wide range of symptoms.

A 29-year-old male with Crohn’s disease, recently treated with Infliximab, presented with acute respiratory failure and five days of worsening ascending weakness and numbness in his lower extremities. Endobronchial lymph node biopsy and bronchoalveolar lavage (BAL) revealed necrotizing granulomatous inflammation. Initial infectious studies including acid-fast bacilli (AFB) were negative.

Three weeks later, the patient developed paraplegia that worsened over five days, accompanied by hyporeflexia and respiratory failure. Brain MRI revealed multiple ring-enhancing lesions with surrounding edema in both hemispheres, without diffusion or leptomeningeal enhancement. Spine MRI showed an enhancing intramedullary lesion at T2-3, with cord edema from C4 to T10.

Extensive workup for infections, demyelination, full-body imaging, CSF panel, and autoimmune/paraneoplastic conditions was negative. The patient received five rounds of plasmapheresis and high-dose steroids with no improvement. After 23 days, AFB from BAL tested positive, confirming Mycobacterium tuberculosis complex and the diagnosis of miliary tuberculosis. RIPE therapy (Rifampin, Ethambutol, Isoniazid, Pyrazinamide) was started, leading to improvement of CNS tuberculomas on follow-up MRI.

This case highlights the challenges associated with diagnosing miliary tuberculosis. Delays in diagnosis and treatment can significantly increase mortality rates and expose healthcare providers to greater risk.

This case raises an important question:Should we initiate empirical treatment when there is a high suspicion of tuberculosis? Although there is currently insufficient evidence to provide a definitive answer, it is certainly a consideration worth exploring. Prompt recognition of tuberculosis is critical to mitigate the risks associated with delayed intervention.
