Vascular involvement in type 3 neuronopathic Gaucher's disease

Area of Science:

• Cardiovascular Pathology
• Pediatric Hematology
• Lysosomal Storage Diseases

Background:

• Neuronopathic Gaucher's disease (nGD) is a rare genetic disorder.
• Cardiac complications in nGD are not fully understood.
• Sudden death in pediatric nGD cases warrants investigation.

Observation:

• Autopsy of a pediatric patient with nGD revealed unexpected findings.
• Vascular abnormalities included Gaucher cells and intimal-medial fibrosis in the aorta.
• The myocardium showed widespread acute hemorrhagic necrosis of the left ventricle.

Findings:

• The patient presented with eccentric intimal fibrosis of coronary arteries.
• Left ventricular hypertrophy and pulmonary involvement were noted.
• Anemia was a significant comorbidity.

Implications:

• These findings highlight potential cardiovascular manifestations of nGD.
• Vascular pathology may be a critical factor in sudden death in pediatric nGD.
• Further research is needed to understand and manage cardiac risks in nGD.
