Homocystinuria with transverse sinus thrombosis

Area of Science:

• Neurology
• Metabolic Disorders
• Pediatrics

Background:

• Cerebral venous thrombosis (CVT) in children presents with diverse symptoms and multiple causes.
• Homocystinuria is an underdiagnosed metabolic disorder that can contribute to CVT.
• Routine screening for homocystinuria is not standard practice, potentially delaying diagnosis.

Observation:

• A case report details a girl experiencing drug-resistant partial epilepsy and left transverse cerebral sinus thrombosis.
• The patient was diagnosed with homocystinuria after presenting with acute cerebral symptoms attributed to venous thrombosis.
• This case highlights the diagnostic challenges and delayed identification of homocystinuria.

Findings:

• Homocystinuria was identified as the underlying cause of cerebral venous thrombosis in a pediatric patient.
• The diagnosis of homocystinuria was confirmed following the onset of severe cerebral symptoms.
• This underscores the importance of considering metabolic disorders in unexplained CVT.

Implications:

• Highlights the need to include homocystinuria in the differential diagnosis for pediatric cerebral venous thrombosis.
• Emphasizes the potential for medical treatment of homocystinuria to prevent or manage thrombotic events.
• Suggests that earlier diagnostic consideration of homocystinuria could improve patient outcomes and prevent severe neurological complications.
