Insights

This report details a rare case of dolicho-ectasia affecting multiple cerebral arteries in a child, causing brainstem compression. Magnetic Resonance angiography proved valuable in diagnosing this significant vascular anomaly.

Area of Science:

  • Neurology
  • Vascular Neurology
  • Pediatric Neurology

Background:

  • Cerebral artery dolicho-ectasia is a rare vascular condition characterized by abnormal dilation and elongation of cerebral arteries.
  • While typically affecting a single artery, involvement of multiple cerebral arteries, especially in children, is exceptionally uncommon.

Observation:

  • A 5-year-old boy presented with symptoms attributed to dolicho-ectasia of the left posterior cerebral artery and internal carotid artery.
  • The vascular anomaly resulted in significant compression of critical brain structures, including the brainstem, mammillary bodies, and optic tract.

Findings:

  • Magnetic Resonance angiography (MRA) effectively visualized the complex vascular anatomy and confirmed the diagnosis of multi-arterial dolicho-ectasia.
  • The case highlights the diagnostic utility of MRA in identifying rare pediatric vascular malformations.

Implications:

  • This case underscores the importance of considering rare vascular anomalies in pediatric neurological assessments.
  • Early and accurate diagnosis through advanced imaging like MRA is crucial for managing potential complications arising from brainstem and neural pathway compression.
