title: Recurrent parotid adenocarcinoma occurring within the cerebellopontine angle.
abstract: A patient presented 3 1/2 years after resection of a malignant parotid tumor with a new cerebellopontine angle mass. The presence of multiple punctate calcifications and loss of T2 signal were helpful in correctly identifying the lesion as mucinous adenocarcinoma.
