Summary
Polyarteritis nodosa (PAN), a rare vasculitis, can present with neurological and systemic symptoms. Early diagnosis via angiography and HBsAg testing is crucial for managing this severe condition.
Area of Science:
- Internal Medicine
- Neurology
- Rheumatology
Background:
- Polyarteritis nodosa (PAN) is a systemic necrotizing vasculitis affecting medium-sized arteries.
- Hepatitis B virus (HBV) infection is a known, though not universal, cause of PAN.
- PAN can manifest with diverse clinical symptoms, including neurological deficits.
Observation:
- A 54-year-old male presented with a 6-month history of sensorimotor polyneuropathy, anorexia, weight loss, fatigue, arthralgia, myalgia, fever, and hypertension.
- Laboratory findings revealed leucocytosis, elevated ESR, positive HBsAg, and cryoglobulins.
- Angiography demonstrated numerous aneurysms, predominantly in the hepatic and renal circulations.
Findings:
- The patient's presentation was consistent with polyarteritis nodosa.
- The presence of HBsAg suggested a potential viral etiology.
- Angiographic evidence of aneurysms confirmed the diagnosis of PAN.
Implications:
- This case highlights the importance of considering PAN in patients with unexplained polyneuropathy and systemic symptoms.
- Hepatitis B surface antigen (HBsAg) testing is vital for identifying a treatable cause of PAN.
- Angiography remains a key diagnostic tool for visualizing the characteristic aneurysms in PAN.
