Summary:

Description
  • Radiopaedia case ID: 24877
  • Image ID: 4701701
  • Plane projection: H&E
  • Study description: Histology
  • Study findings: MICROSCOPIC DESCRIPTION: The section shows fragments of blood clot consisting predominantly of red blood cells with a small amount of fibrin.  At one edge there are several small caliber blood vessels.  These show thickening and hyalinisation of their walls.  Immunohistochemistry shows strong staining for A-beta protein within vessel walls.  The features are of amyloid angiopathy.  No evidence of tumor is seen. FINAL DIAGNOSIS: A-beta amyloid angiopathy with hemorrhage.
  • Modality: Pathology
  • System: Central Nervous System
  • Findings: There is a large right parietal/temporo/occipital/temporal hematoma measuring approximately 5.4cm x 3.7m with a large amount of surrounding edema. There is significant mass-effect, characterized by right cortical sulcal effacement, compression of the right lateral and third ventricles, right uncal herniation and 8mm of leftward midline shift. Temporal horn dilatation is consistent with early hydrocephalus. CTA COW (not shown) The extracranial vessels, circle of willis and vertebrobasilar system opacify normally.  No evidence of aneurysm, vascular malformation, dissection or significant stenosis.
