Area of Science:

  • Nephrology
  • Neurology
  • Rheumatology

Background:

  • Polyarteritis nodosa (PAN) is a systemic vasculitis characterized by necrotizing inflammation of medium-sized arteries.
  • Malignant hypertension is a severe complication associated with various underlying conditions.
  • The clinical presentation of PAN can be diverse, but specific neurological manifestations are not widely recognized.

Observation:

  • This case report details a patient presenting with severe hypertensive encephalopathy.
  • Diagnostic workup revealed underlying Polyarteritis nodosa (PAN) as the cause of the malignant hypertension.
  • Hypertensive encephalopathy was the initial and primary presenting neurological feature of PAN.

Findings:

  • Polyarteritis nodosa (PAN) can manifest with hypertensive encephalopathy, a presentation not previously documented in medical literature.

  • Early recognition of PAN is crucial in patients with unexplained malignant hypertension and neurological symptoms.
  • This finding expands the spectrum of neurological complications associated with PAN.

    • Implications:

    • Highlights the importance of considering PAN in the differential diagnosis of hypertensive encephalopathy.
    • Suggests a need for increased awareness among clinicians regarding this rare presentation of PAN.
    • Underscores the potential for severe neurological sequelae if PAN is not promptly diagnosed and treated.
