[Bilateral deafness, an initial manifestation of meningeal carcinomatosis].

Abstract

Three cases of bilateral deafness with cytologically-demonstrated meningeal carcinomatosis are reported. The first patient, a 64-year old man, presented with bilateral deafness, gait disturbances, and bilateral facial paresis. The second patient, a 78-year-old man, had bilateral deafness, unsteady gait and fluctuations in consciousness. The last patient, a 69-year-old man, complained of bilateral deafness and severe headache, and presented with right facial paresis and left laterodeviation while walking. All three patients had abnormal cochleo-vestibular findings and brainstem auditory evoked responses (BAER) that suggested peripheral lesions with absent or very delayed I waves. The brain CT scans with an without contrast enhancement were entirely normal, and the diagnosis was established by lumbar puncture. From our own cases and a review of the literature, deafness in meningeal carcinomatosis may start unilaterally but becomes bilateral in less than a week. Vestibular disturbances may not be apparent, but they can be demonstrated in almost all cases. Facial paresis or plegia is also a very frequent finding. The destruction of the eighth and seventh cranial nerves is probably due to direct infiltration by neoplastic cells as well as to ischemia through compression of the nerve supplying vessels. The 3 cases presented here emphasize once again the important fact that meningeal carcinomatosis remains a cytological diagnosis, several lumbar punctures being sometimes necessary, and that cerebrospinal fluid studies cannot yet be supplanted by other diagnostic techniques like contrast-enhanced CT or MRI with gadolinium.
