[Recurrent periarteritis nodosa with predominantly cerebral signs in children (author's transl)]
Insights
Periarteritis nodosa, a serious vasculitis, can affect children with diverse symptoms. This case highlights severe neurological and cardiac complications, including coronary artery aneurysm rupture, in a pediatric patient.
Area of Science:
- Pediatric Rheumatology
- Vascular Pathology
Background:
- Periarteritis nodosa (polyarteritis nodosa) is a systemic necrotizing vasculitis affecting medium-sized arteries.
- While it can occur in children, its presentation and complications in pediatric populations require careful consideration.
Observation:
- A 4 1/2-year-old girl presented with a complex clinical course suggestive of periarteritis nodosa.
- Initial symptoms included encephalitis-like neurological disturbances, severe arterial hypertension, and intestinal wall necrosis.
- The disease course was further complicated by liver and skeletal muscle involvement with hepatic necrosis, and ultimately, pericardial tamponade due to coronary artery aneurysm rupture.
Findings:
- The case demonstrated a wide spectrum of signs and symptoms mirroring adult presentations of periarteritis nodosa.
- Morphological examination revealed distinctive endarteritic changes in retroperitoneal and coronary arteries, contributing to the observed pathology.
- The rupture of a coronary artery aneurysm led to a fatal outcome via pericardial tamponade.
Implications:
- This case underscores the critical need for early recognition and management of periarteritis nodosa in children, given its potential for severe, life-threatening complications.
- The findings emphasize the importance of considering vasculitis in pediatric patients with unexplained neurological, gastrointestinal, and cardiac symptoms.
- Understanding the peculiar morphological features, such as endarteritis, is crucial for accurate diagnosis and potentially for developing targeted therapies.
Abstract:
Periarteritis nodosa occurs also in children and has the same wide spectrum of signs and symptoms as in adults. In a 4 1/2 year-old girl the disease at first was characterised by cerebral, encephalitis-like symptoms, arterial hypertension, intestinal wall necrosis and, finally, pericardial tamponade as a result of rupture of an arteritic coronary artery aneurysm. An earlier attack had involved liver and skeletal muscle, with necrosis in the liver. Peculiar morphological features within the "classical" course of periarteritis nodosa are endarteritic changes of single retroperitoneal and coronary arteries.
