Sudden death in an infant caused by rupture of a basilar artery aneurysm
1Regina Medical Center, Hastings, Minnesota 55033, USA.
Insights
Ruptured cerebral aneurysms are rare in infants and can mimic trauma. This case details the sudden death of an infant due to a basilar artery aneurysm rupture.
Area of Science:
- Neurology
- Pediatrics
- Pathology
Background:
- Cerebral aneurysms are uncommon in infants and young children.
- Presenting signs in infants differ from older patients, often lacking typical symptoms like headache.
- Morphologic findings can be misdiagnosed as inflicted trauma.
Purpose of the Study:
- To report a rare case of sudden infant death due to a ruptured cerebral aneurysm.
- To highlight the diagnostic challenges and autopsy findings in such cases.
- To emphasize the importance of considering vascular anomalies in unexplained infant deaths.
Main Methods:
- Case report of a 7-month-old infant with sudden death.
- Detailed investigation including autopsy and neuropathological examination.
- Analysis of the ruptured basilar artery aneurysm morphology.
Main Results:
- The infant presented with sudden death, attributed to a ruptured complex basilar artery aneurysm.
- Autopsy revealed findings consistent with subarachnoid hemorrhage.
- The case underscores the potential for misdiagnosis of ruptured aneurysms as trauma in infants.
Conclusions:
- Sudden death from a ruptured cerebral aneurysm is a previously undescribed event in infancy.
- Accurate diagnosis requires awareness of rare cerebrovascular pathologies in this age group.
- Early identification of cerebral aneurysms is crucial to prevent catastrophic outcomes.
Abstract:
Ruptured aneurysms of the cerebrovasculature in infancy and early childhood, except for "giant" aneurysms and arteriovenous malformations, are rare. Seizures, loss of consciousness, and apnea are the usual presenting signs in infancy; symptoms such as headache or visual disturbances and signs such as cranial nerve compression or meningeal irritation commonly found in older children or adults are absent in infants. However, the morphologic findings (i.e., subarachnoid and retinal hemorrhage, and occasionally subdural hemorrhage) may be mistaken for inflicted trauma, especially if the aneurysm is not identified. Sudden death caused by rupture of a cerebral aneurysm has not been previously described in an infant. This report outlines the investigation and autopsy findings in a 7-month-old infant who died unexpectedly as a result of rupture of a complex basilar artery aneurysm.
