Hemorrhagic cerebral white matter: infarction with cerebral deep venous thrombosis and hypoxia
Abstract:
Postmortem examination of the brain of a 5-week-old boy disclosed extensive thrombosis of the deep venous system and widespread necrosis of the cerebral parenchyma. As is characteristic of this uncommon form of cerebrovascular disease, malacia was present in the central gray matter but was only focal and incospicuous in contrast to a diffuse hemorrhagic softening of the centrum semiovale. This association of deep venous thrombosis and predominant white matter necrosis suggests that impairment of venous drainage should be considered in the pathogenesis of certain disorders of the cerebral white matter.
Insights
Extensive deep venous thrombosis in an infant brain led to widespread cerebral parenchyma necrosis, primarily affecting white matter. Impaired venous drainage is implicated in the pathogenesis of such white matter disorders.
Area of Science:
- Neuropathology
- Cerebrovascular Diseases
- Pediatric Neurology
Background:
- Cerebrovascular diseases in infants are uncommon but can have severe consequences.
- Thrombosis of the deep venous system is a rare but significant finding in pediatric postmortem examinations.
Observation:
- Postmortem examination of a 5-week-old boy's brain revealed extensive deep venous system thrombosis.
- Widespread necrosis of the cerebral parenchyma was observed, with focal malacia in the central gray matter.
- A diffuse hemorrhagic softening predominantly affected the centrum semiovale white matter.
Findings:
- The case presents a characteristic pattern of cerebrovascular disease with deep venous thrombosis.
- A predominant white matter necrosis, contrasting with focal gray matter changes, was noted.
- The findings highlight an association between deep venous thrombosis and white matter injury.
Implications:
- Impaired venous drainage is suggested as a key factor in the pathogenesis of specific cerebral white matter disorders.
- This case underscores the importance of considering venous system involvement in infant neuropathology.
- Further research into the mechanisms of venous drainage impairment in pediatric cerebrovascular events is warranted.
