Pediatric Choroid Plexus Hemorrhage

  • Etiology: Hemorrhage within choroid plexus
  • Imaging US:
    — Enlarged, irregular, heterogenous choroid plexus
    — Change in appearance on serial exams or associated intraventricular hemorrhage are supportive of diagnosis
  • DDX: Normal choroid plexus – can be difficult to diagnose because body of choroid plexus is normally bulbous and echogenic
  • Complications:
  • Treatment:
  • Clinical: More common in term than preterm infants

Radiology Cases of Choroid Plexus Hemorrhage

Head US of choroid plexus hemorrhage
Coronal (left) and left sagittal (right) US of the brain shows the left-sided choroid plexus in the left lateral ventricle to be abnormally enlarged, irregular in contour and heterogenous in appearance when compared to the normal right-sided choroid plexus in the right lateral ventricle.
US and MRI of choroid plexus hemorrhage
Coronal (above left) and sagittal (above right) US of the brain show the right lateral ventricle to be filled with echogenic material and to be dilated. Axial GRE MRI without contrast of the brain obtained 1 month later (below) shows dark signal representing hemosiderin in the choroid plexus of the right lateral venticle. There is no hemosiderin in the right germinal matrix.
