Tumor-associated hemorrhage in patients with acoustic neuroma.
OBJECTIVE
To describe the clinical significance of tumor-associated hemorrhage in patients with acoustic neuromas.


METHODS
Retrospective chart review.


METHODS
University-based, tertiary care teaching hospital.


METHODS
Three patients with acoustic neuromas who experienced symptomatic tumoral bleeding.


METHODS
Radiographic imaging, surgical removal of tumors, and pathologic analysis.


METHODS
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.


CONCLUSIONS
These findings have implications for those patients with acoustic neuromas who choose not to have surgical removal.
