Summary
Primary medullary hemorrhages occurred in two normotensive patients on oral anticoagulation. CT scans confirmed diagnosis and resolution, correlating with good clinical outcomes.
Area of Science:
- Neurology
- Radiology
Background:
- Primary medullary hemorrhage is a rare cerebrovascular event.
- Understanding risk factors and outcomes in anticoagulated patients is crucial.
Observation:
- Two normotensive patients on oral anticoagulation developed primary medullary hemorrhages.
- Coagulation studies were not excessively prolonged at the time of hemorrhage.
Findings:
- Computed tomography (CT) confirmed the diagnosis of primary medullary hemorrhage in both cases.
- CT demonstrated resolution of the hemorrhages in both patients.
- Hemorrhage resolution on CT correlated with favorable clinical outcomes.
Implications:
- This suggests that primary medullary hemorrhage can occur even with therapeutic anticoagulation levels.
- CT imaging is valuable for diagnosing and monitoring medullary hemorrhages.
- Favorable outcomes may be associated with early detection and resolution.
