Spontaneous splenic rupture in polyarteritis nodosa.

G A Ford, J R Bradley, D S Appleton

    Postgraduate Medical Journal
    |October 1, 1986
    PubMed
    Summary

    Polyarteritis nodosa, a rare vasculitis, can cause spontaneous splenic rupture and kidney damage. This case highlights the severe complications of necrotizing vasculitis in medium and small arteries.

    Area of Science:

    • Nephrology
    • Vascular Surgery
    • Rheumatology

    Background:

    • Polyarteritis nodosa (PAN) is a systemic necrotizing vasculitis affecting medium-sized arteries.
    • PAN can manifest with diverse organ involvement, including renal and splenic complications.

    Observation:

    • A 28-year-old male presented with hematuria and renal failure.
    • Renal arteriography identified bleeding from a hilar artery into a solitary right kidney and multiple splenic artery aneurysms.
    • The patient experienced spontaneous splenic rupture requiring splenectomy and nephrectomy.

    Findings:

    • Histological examination confirmed acute necrotizing vasculitis, consistent with PAN.
    • The vasculitis involved medium and small arteries in the spleen and kidney.
    • Splenic infarction was noted in the subcapsular region.

    Implications:

    • Spontaneous splenic rupture is a rare but critical complication of systemic vasculitis.
    • This case underscores the importance of recognizing vascular abnormalities in PAN.
    • Early diagnosis and management of PAN are crucial to prevent life-threatening complications.
