MRA or CTA, that's the question.

Summary

A young woman experienced painful oculomotor palsy, leading to the discovery of a posterior communicating artery aneurysm via computed tomographic angiography. This case highlights neuroimaging techniques for diagnosing intracranial aneurysms.

Area of Science:

  • Neuro-ophthalmology
  • Vascular Neurology
  • Diagnostic Imaging

Background:

  • Oculomotor palsy can present with various etiologies, including vascular abnormalities.
  • Intracranial aneurysms, particularly posterior communicating artery aneurysms, are a critical cause of cranial nerve palsies.

Observation:

  • A 26-year-old female presented with acute, painful left oculomotor nerve palsy involving pupillary function.
  • Initial magnetic resonance imaging (MRI) and magnetic resonance angiography (MRA) of the brain and orbits were unremarkable.

Findings:

  • Computed tomographic angiography (CTA) successfully identified a 7-mm left posterior communicating artery aneurysm.
  • The diagnostic yield of different neuroimaging modalities for intracranial aneurysms is discussed.

Implications:

  • CTA is a valuable tool for detecting intracranial aneurysms when other imaging modalities are inconclusive.
  • Prompt diagnosis and characterization of aneurysms are crucial for preventing rupture and managing neurological deficits.
  • This case underscores the importance of considering vascular etiologies in young patients with oculomotor palsy.
