Calcified cerebellopontine angle hematoma mimicking recurrent acoustic neurinoma

The authors describe a case of calcified, organized hematoma in the cerebellopontine angle which developed 20 years after subtotal removal of an acoustic neurinoma, presenting as a recurrence of acoustic neurinoma on computed tomography. It points out the difficulty in differentiating a recurrent tumor from an organized hematoma in this particular case because of neuroradiological similarity and masked clinical symptoms by the long-standing neurological deficits after the original surgery. MRI scanning would have been helpful in this circumstances.
