Abstract:
Moyamoya syndrome (MMS) is a rare progressive cerebrovascular disorder causing stenosis of intracranial arteries and collateral vessel formation. Pediatric presentations often include ischemic strokes, and coexisting Thalassemia Major may worsen vascular outcomes. A 3-year-old male with Thalassemia Major presented with acute right-sided weakness, altered consciousness, and a prior left-sided stroke. Examination revealed facial asymmetry, aphasia, and right-sided hemiparesis. Laboratory tests excluded metabolic, infectious, and cardio-embolic causes. MRI Brain with contrast and TOF-MRA demonstrated chronic right-sided changes, acute left-sided ischemia, and marked narrowing of the supraclinoid and cavernous segments of the left internal carotid artery, confirming Moyamoya disease, Suzuki stage 3. The patient received aspirin (3 mg/kg/day) and supportive care. After 5 days, neurological status improved (GCS 14, right limb power 3/5). Surgical revascularization via EDAS was advised but deferred due to financial constraints. This case highlights alternating hemiparesis as a rare pediatric MMS presentation, the diagnostic utility of MRI/MRA, and the impact of socio-economic limitations on access to definitive surgical care.
Insights
This case study details a pediatric Moyamoya syndrome (MMS) patient with Thalassemia Major presenting with alternating hemiparesis. Early diagnosis via MRI/MRA and supportive care showed improvement, though financial barriers impacted definitive treatment.
Area of Science:
- Neurology
- Pediatrics
- Vascular Medicine
Background:
- Moyamoya syndrome (MMS) is a rare cerebrovascular disorder characterized by intracranial artery stenosis and collateral formation.
- Pediatric MMS often presents with ischemic strokes, potentially exacerbated by coexisting conditions like Thalassemia Major.
- Thalassemia Major can negatively impact vascular health, increasing risks in pediatric patients with cerebrovascular conditions.
Purpose of the Study:
- To report a rare pediatric case of Moyamoya syndrome presenting with alternating hemiparesis.
- To emphasize the diagnostic role of advanced neuroimaging in pediatric Moyamoya syndrome.
- To highlight the challenges in accessing definitive surgical care due to socio-economic factors.
Main Methods:
- A case report of a 3-year-old male with Thalassemia Major presenting with stroke-like symptoms.
- Diagnostic workup included neurological examination, laboratory tests, MRI Brain with contrast, and TOF-MRA.
- Treatment involved aspirin and supportive care, with surgical revascularization (EDAS) recommended but deferred.
Main Results:
- The patient exhibited acute neurological deficits, including hemiparesis and altered consciousness, consistent with ischemic stroke.
- Neuroimaging confirmed Moyamoya disease (Suzuki stage 3) with significant internal carotid artery stenosis.
- Initial treatment with aspirin led to partial neurological improvement within 5 days.
Conclusions:
- Alternating hemiparesis can be a rare presenting symptom of pediatric Moyamoya syndrome.
- MRI/MRA are crucial for diagnosing Moyamoya disease in children.
- Socio-economic factors significantly influence the accessibility of timely and definitive surgical interventions for Moyamoya syndrome.
