Idiopathic pulmonary arterial hypertension is a rare pediatric disease. Autopsy revealed characteristic arteriopathy lesions, prompting genetic testing for BMPR2 mutations in this fatal case.
Area of Science:
- Pediatric Cardiology
- Hematology
- Pathology
Background:
- Idiopathic pulmonary arterial hypertension (IPAH) is a rare and severe condition in children.
- Early diagnosis and treatment are crucial for managing pediatric IPAH.
- Understanding the underlying pathophysiology is key to improving outcomes.
Observation:
- A 2-year-old boy presented with severe dyspnea and epistaxis.
- Laboratory findings included hemolytic anemia with schizocytes and severe thrombocytopenia.
- Cardiac investigations revealed supra-systemic pulmonary arterial hypertension refractory to treatment.
Findings:
- The patient experienced cardiac arrests and died 8 days after admission.
- Autopsy confirmed idiopathic pulmonary hypertensive arteriopathy with plexiform lesions and microthrombi.
- Genetic analysis of BMPR2 was planned for the patient's family.
Implications:
- This case highlights the aggressive nature of pediatric IPAH.
- Autopsy findings provide critical insights into the disease's pathology.
- Family screening and genetic studies are essential for identifying potential hereditary factors.
