Clinical Report: Uncommon Presentation of Isolated Renal Tuberculosis

Background

Isolated renal tuberculosis is a rare extrapulmonary manifestation of tuberculosis that can mimic urinary tract infections, leading to delayed diagnosis.

Data Highlights

No numerical or trial data available in the source material.

Key Findings

  • The patient was a 77-year-old diabetic man with a history of renal calculus disease and recurrent urinary tract infections.
  • Diagnostic imaging revealed extensive renal destruction and a hyperenhancing mass suggestive of renal cell carcinoma.
  • Histopathological examination confirmed renal tuberculosis and its associated complications post-nephrectomy.
  • Antitubercular therapy resulted in stable clinical and functional outcomes.

Clinical Implications

Early imaging and histopathological assessment are crucial for the timely diagnosis of isolated renal tuberculosis.

Conclusion

This case highlights the indolent nature of isolated renal tuberculosis.
