Objective:
To describe the clinical significance of tumor-associated hemorrhage in patients with acoustic neuromas.
Study Design:
Retrospective chart review.
Setting:
University-based, tertiary care teaching hospital.
Patients:
Three patients with acoustic neuromas who experienced symptomatic tumoral bleeding.
Interventions:
Radiographic imaging, surgical removal of tumors, and pathologic analysis.
Main Outcome Measures:
Patient histories, radiologic characteristics, surgical results, and pathologic findings.
Results:
Tumoral hemorrhage can occur in patients with acoustic neuromas. These three cases and a review of the world literature suggest that tumor size may be the most important risk factor for tumor-related hemorrhage.
Conclusion:
These findings have implications for those patients with acoustic neuromas who choose not to have surgical removal.
