Disseminated tuberculosis can mimic other diseases, presenting diagnostic challenges even with biopsies. This case highlights the importance of considering tuberculosis in patients with bone destruction and enlarged lymph nodes.

Area of Science:

  • Infectious Diseases
  • Radiology
  • Orthopedic Surgery

Background:

  • Disseminated tuberculosis (tuberculosis) is a severe form of Mycobacterium tuberculosis infection that can affect multiple organ systems.
  • Psoas abscesses and skeletal lesions are known, though less common, manifestations of disseminated tuberculosis.
  • Differential diagnosis can be challenging, especially when initial pathological findings are equivocal.

Observation:

  • A 28-year-old male presented with disseminated tuberculosis, including a psoas abscess and significant bone destruction.
  • Radiographs initially suggested metastatic malignancy due to multiple skeletal lesions and hilar adenopathy.
  • Initial pathological specimens were inconclusive for acid-fast bacilli.

Findings:

  • Special stains on biopsy specimens ultimately confirmed the diagnosis of tuberculosis.

  • The clinical presentation and initial imaging findings mimicked disseminated malignancy, underscoring diagnostic difficulties.
  • Successful treatment was achieved through a combination of surgical intervention and chemotherapy.

    • Implications:

    • This case emphasizes that disseminated tuberculosis can present with diverse and misleading clinical and radiological features.
    • It highlights the critical role of specialized staining techniques in diagnosing tuberculosis when initial methods fail.
    • Early and accurate diagnosis, despite mimicry of other conditions, is crucial for effective management and therapeutic outcomes in disseminated tuberculosis.
