Subcortical hemorrhage

Last edited: 4/22/2026

Overview

Subcortical hemorrhage involves bleeding within the subcortical white matter, often impacting swallowing function and potentially harboring occult vascular malformations that may necessitate further investigation to prevent rebleeding. 12

Diagnosis

  • Clinical Assessment: Includes evaluation of swallowing function using scales like the Clinical Dysphagia Scale (CDS). 1
  • Imaging: Initial neuroimaging (CT/MRI) to assess hemorrhage size and location.
  • Repeat Angiography: Recommended for patients under 65 years without identifiable source on initial angiography or MRI, to detect occult vascular malformations. 2
  • Management

  • Supportive Care: Focus on managing complications such as dysphagia, respiratory issues, and intracranial pressure.
  • Neurological Monitoring: Regular assessment for signs of increased intracranial pressure or rebleeding.
  • Repeat Imaging: For patients with negative initial angiographic findings, repeat angiography and MRI may be indicated to identify potential sources of bleeding. 2
  • Special Populations

  • Elderly: Larger hemorrhage size correlates with more severe dysphagia, particularly notable in those over 70 years old. 1
  • Key Recommendations

  • Evaluate swallowing function rigorously in subcortical hemorrhage patients using scales like CDS to correlate with hemorrhage size, especially in elderly patients. (Evidence: Moderate) 1
  • Consider repeat angiography and MRI in younger patients (<65 years) with subcortical hemorrhage and no identifiable source on initial imaging to rule out occult vascular malformations. (Evidence: Moderate) 2
  • Tailor dysphagia management based on the severity assessed by CDS, recognizing that larger hemorrhages are associated with more pronounced dysphagia symptoms. (Evidence: Moderate) 1
