Moyamoya syndrome associated with sickle cell trait in a child

Area of Science:

• Neurology
• Hematology
• Pediatric Medicine

Background:

• Moyamoya syndrome is a progressive cerebrovascular disease characterized by arterial occlusion and collateral vessel formation.
• It is frequently associated with hemoglobinopathies, including sickle cell disease.
• The co-occurrence of moyamoya syndrome and sickle cell trait is exceptionally rare.

Observation:

• A 7-year-old boy presented with headaches and was diagnosed with moyamoya syndrome.
• The patient was also found to have sickle cell trait.
• This represents a unique pediatric presentation of this combined condition.

Findings:

• The diagnosis of moyamoya syndrome in a child with sickle cell trait is exceedingly uncommon.
• This case adds to the limited literature on this specific comorbidity.
• The patient's presentation is the first reported instance in a pediatric patient.

Implications:

• This case underscores the importance of considering moyamoya syndrome in children with sickle cell trait presenting with neurological symptoms.
• Further research may elucidate the pathophysiological links between these conditions.
• Early recognition and management are crucial for improving outcomes in affected children.
