Summary
Intraventricular hemorrhage (IVH) is rare in healthy term infants. This case reveals a previously undetected arteriovenous malformation (AVM) as the cause of IVH, even after initial imaging.
Area of Science:
- Neonatal neurology
- Pediatric neurosurgery
- Vascular malformations
Background:
- Intraventricular hemorrhage (IVH) is an uncommon complication in term neonates.
- Arteriovenous malformations (AVMs) are rare causes of IVH in this population.
Observation:
- A term infant presented with intraventricular hemorrhage.
- Initial cranial ultrasonogram and magnetic resonance angiogram were unremarkable for vascular abnormalities.
Findings:
- Angiography revealed an arteriovenous malformation (AVM) as the source of the IVH.
- The AVM was not detected by initial non-invasive imaging modalities.
Implications:
- Highlights the importance of considering AVMs in term neonates with unexplained IVH.
- Suggests limitations of standard imaging in diagnosing certain AVMs in neonates.
- Emphasizes the role of conventional angiography in definitive diagnosis.
