Natural History, Complications and Prognosis

Natural History

The natural course of lymphadenopathy depends on the underlying cause. Lymphadenopathy due to infectious causes subsides once the infection is controlled.

Complications

• Mediastinal lymphadenopathy causes pressure symptoms like:
  • Superior vena cava syndrome
  • Tracheal and bronchial obstruction
  • Dysphagia
  • Hemoptysis
• Uric acid nephropathy
• Hyperkalemia
• Hypercalcemia
• Hypocalcemia
• Hyperphosphatemia
• Renal failure

Prognosis

Prognosis of lymphadenopathy depends entirely on the underlying etiology. Cancerous causes of lymphadenopathy have a poor prognosis compared to the infectious causes.
