Insights

Tuberculous arthritis, a rare condition, can mimic inflammatory arthritis. Magnetic resonance imaging (MRI) findings suggested tuberculosis in three knee arthritis cases, confirmed by histology.

Area of Science:

  • Rheumatology
  • Infectious Diseases
  • Radiology

Context:

  • Tuberculous arthritis is an uncommon manifestation of tuberculosis.
  • It is often misdiagnosed as inflammatory arthritis due to overlapping clinical presentations.
  • Limited case reports exist detailing MRI findings in tuberculous arthritis.

Purpose:

  • To report three cases of tuberculous arthritis of the knee.
  • To highlight the diagnostic utility of MRI in suspected tuberculous arthritis.
  • To emphasize the importance of histological confirmation.

Summary:

  • Three patients presented with insidious knee pain suggestive of tuberculous arthritis.
  • MRI revealed abnormalities consistent with tuberculosis in all cases.
  • Histological examination confirmed the diagnosis of tuberculous arthritis.

Impact:

  • This case series underscores the potential of MRI to identify tuberculous arthritis.
  • It aids in differentiating tuberculous arthritis from other forms of arthritis.
  • Early and accurate diagnosis can lead to timely treatment and improved patient outcomes.
