Summary:

Description
  • Radiopaedia case ID: 37000
  • Image ID: 12879084
  • Study findings: MICROSCOPIC DESCRIPTION: 1&2. The sections show fragments of cerebellar cortex and white matter. There is recent hemorrhage within white matter extending focally into cortex. Adjacent white matter shows prominent proliferation of small caliber vascular channels. These are lined by plump endothelial cells. There is edema and reactive gliosis within intervening white matter. Several native blood vessels show thickening and hyalinisation of their walls. There is no evidence of active vasculitis. Within cerebellar white matter adjacent to the hemorrhage there is prominent infiltration by neutrophils. No organisms are identified. No evidence of tumor is seen. Immunostaining for A-beta protein is negative. DIAGNOSIS: 1&2. Hematoma wall 1&2: Recent intracerebellar hemorrhage - see comment. COMMENT: The features in the specimens submitted, in particular the hyaline thickening of the walls of small native blood vessels, are most consistent with hypertensive intracerebellar hemorrhage. However, the presence of neutrophils within adjacent white matter raises the possibility of mycotic aneurysm.
  • Modality: Pathology
  • System: Central Nervous System
  • Findings: MRI brain shows a hemorrhagic, well-defined, left cerebellar lesion associated with mild surrounding edema and no significant mass effect. No hydrocephalus. MRA and MRV unremarkable.
