Basilar artery dissection, though rare, can cause pontine infarction without trauma. Magnetic resonance angiography and imaging effectively diagnose this condition, aiding stroke management.

Area of Science:

  • Neurology
  • Vascular Neurology
  • Neuroimaging

Background:

  • Cervicocerebral artery dissection is a recognized cause of stroke, particularly in younger individuals without traditional cardiovascular risk factors.
  • Dissection of the basilar artery is an uncommon but serious vascular event.

Observation:

  • A 51-year-old male presented with acute pontine infarction.
  • The infarction was associated with dissection of the distal basilar artery.
  • No preceding trauma or unusual head/neck movement was reported.

Findings:

  • Non-invasive diagnosis of basilar artery dissection was achieved using magnetic resonance imaging (MRI) and magnetic resonance angiography (MRA).
  • The case highlights a rare instance of basilar artery dissection leading to pontine infarction.

Implications:

  • This case underscores the utility of MRI and MRA in the non-invasive diagnosis of cervicocerebral artery dissections.
  • Early and accurate diagnosis through advanced imaging can guide appropriate management strategies for stroke secondary to arterial dissection.
