A 47-year-old previously healthy woman presented to the emergency department with acute onset of headache, dizziness, and right-sided hearing loss. She was afebrile, normotensive, alert, and oriented, without focal neurologic deficit. She had no history of hearing loss or imbalance and no family history of stroke. The results of coagulation studies were normal. Initial unenhanced computed tomographic images of the brain revealed a 2.5-cm, rounded, hyperdense, extra-axial mass in the right cerebellopontine (CP) angle (Figure 1).
