Insights
Pediatric pulmonary embolism (PE) is uncommon and often missed. This study highlights four childhood cases associated with diverse conditions, emphasizing the need for increased diagnostic awareness in pediatric patients.
Area of Science:
- Pediatric Medicine
- Cardiology
- Pulmonology
Background:
- Pulmonary embolism (PE) is a rare condition in children, often underdiagnosed.
- Early identification and management are crucial for favorable outcomes.
Observation:
- Four pediatric cases (ages 5-13) with PE were identified.
- Associated primary diagnoses included craniopharyngioma, asthma, Crohn's Disease, and Reye's syndrome.
- Elevated plasma osmolalities were noted in three patients.
Findings:
- Technetium micro aggregate lung perfusion scans confirmed PE in three children.
- Autopsy in one non-surviving child revealed femoral vein thrombosis.
- The origin of emboli in three patients remained undetermined.
Implications:
- This case series underscores the importance of considering PE in pediatric patients with unexplained respiratory symptoms.
- Recognizing diverse underlying conditions associated with pediatric PE can aid diagnosis.
- Further research into risk factors and diagnostic strategies for childhood PE is warranted.
Abstract:
Pulmonary embolism in childhood is a rare but under-diagnosed condition. We report four children aged 5 to 13 years presenting with pulmonary emboli, their primary diagnoses being craniopharyngioma, asthma, Crohn's Disease and Reye's syndrome. The diagnosis was supported by technetium micro aggregate lung perfusion scans in three of the children and in the fourth, the only child to die, by autopsy. Three of the children had markedly elevated plasma osmolalities, one as a result of his diabetes insipidus and two following hyperosmolar treatment for cerebral oedema. The child who died was found to have a femoral vein thrombosis but the sites of origin of emboli in the other children were not defined.
