title: [Bilateral progressive hearing loss as the first manifestation of metastatic carcinoma of the head of the pancreas. Case report].
abstract: We report the history of a patient who presented first with a progressive unilateral hearing loss and later with a bilateral deafness and an unilateral facial nerve palsy as first and only symptoms of a pancreatic adenocarcinoma. By means of magnetic resonance tomography tumor-suspect lesions in both internal auditory canals were detected. Referring to the results of further examinations these intracanalicular lesions are most probably due to rarely seen bilateral metastasis of a pancreatic adenocarcinoma in the temporal bone. In addition to this rarely diagnosed localisation of metastasis it is rather uncommon that this kind of primary malignoma had not been detected because of gastrointestinal symptoms or extracranial metastasis.
