Summary

Choroid plexus infarction, a rare stroke affecting the brain's choroid plexus, can be visualized using diffusion-weighted imaging. This study explores its clinical and imaging features.

Area of Science:

  • Neurology
  • Radiology
  • Neuroanatomy

Background:

  • The choroid plexus produces cerebrospinal fluid and is supplied by the medial posterior choroidal artery.
  • Ischemia in this artery's territory can lead to choroid plexus infarction.
  • This condition is a rare cause of stroke with distinct clinical and radiological presentations.

Purpose of the Study:

  • To describe the clinical and radiological features of choroid plexus infarction.
  • To highlight the utility of diffusion-weighted imaging in diagnosing this condition.
  • To correlate imaging findings with the anatomy and pathophysiology of the choroid plexus.

Main Methods:

  • Review of clinical data and neuroimaging studies (specifically diffusion-weighted imaging) of patients with confirmed choroid plexus infarction.
  • Anatomical review of the medial posterior choroidal artery supply to the choroid plexus.
  • Pathophysiological analysis of ischemic events affecting the choroid plexus.

Main Results:

  • Diffusion-weighted imaging effectively depicts acute infarction in the choroid plexus.
  • Clinical presentation may include focal neurological deficits depending on the affected area.
  • Radiological findings correlate with the vascular territory of the medial posterior choroidal artery.

Conclusions:

  • Choroid plexus infarction is an uncommon stroke syndrome.
  • Diffusion-weighted imaging is a sensitive tool for its diagnosis.
  • Understanding choroid plexus anatomy and pathophysiology is crucial for interpreting imaging findings.
