Systemic necrotizing vasculitis can initially present as a hypertensive crisis with encephalopathy, especially in younger patients. Early diagnosis via renal angiography is crucial for effective treatment and blood pressure control.

Area of Science:

Nephrology
Rheumatology
Internal Medicine

Background:

Hypertension is often considered an insidious complication of necrotizing vasculitis.
Necrotizing vasculitis is typically not a primary consideration in hypertensive crisis diagnosis.

Observation:

Three cases are presented where hypertensive crisis with encephalopathy was the initial manifestation of systemic necrotizing vasculitis.
Patients were younger, had elevated erythrocyte sedimentation rates (ESRs), and showed evidence of prior hepatitis B virus exposure.
Metabolic alkalosis was present in all patients; hyponatremia and hypokalemia were noted in two.

Findings:

Systemic necrotizing vasculitis can manifest dramatically as a life-threatening hypertensive crisis.
Renal angiography confirmed the diagnosis and is justified in similar clinical presentations.

Hypertension control is contingent upon successful treatment of the underlying vasculitis.

Implications:

This challenges the traditional view of hypertension in necrotizing vasculitis as solely progressive.
Highlights the importance of considering necrotizing vasculitis in the differential diagnosis of hypertensive crisis, particularly in specific patient demographics.
Effective therapies exist for necrotizing vasculitis, underscoring the need for timely and accurate diagnosis.
