Acoustic Neurinoma with a Large Organized Hematoma —Case Report

A 66-year-old female presented with a large organized hematoma within an acoustic neurinoma. She had suffered from diminished hearing for 20 years and had headache 1 week before presentation. Computed tomography demonstrated an inhomogeneously high density cerebellopontine angle mass, and magnetic r...

description A 66-year-old female presented with a large organized hematoma within an acoustic neurinoma. She had suffered from diminished hearing for 20 years and had headache 1 week before presentation. Computed tomography demonstrated an inhomogeneously high density cerebellopontine angle mass, and magnetic resonance imaging showed a mass with heterogeneous intensity and gadoliniumdiethylenetriaminepenta-acetic acid enhancement of only the peripheral surface of the mass and the inner parts of the internal auditory meatus. At operation the majority of the mass was soft and featureless with a firm capsule, and a yellowish soft tumor was removed from the perimeatal area. Histological examination showed the mass was an acoustic neurinoma with a large organized hematoma. Extensive hemorrhage from an abnormal vascularity in the tumor had repeated followed by granulomatous organization.
