The author reported a 45-year-old woman with numerous developmental anomalies in whom lingual hemiatrophy preceded by strong occipital headaches followed tonsillectomy. After treatment considerable regeneration of tongue nuscle took place. The course of the disease was recurrent. In the differential diagnosis the author considered inflammatory processes, neoplastic diseases, developmental anomalies and toxic effect of procaine used in tonsillectomy as well as the possibility of deeply situated adhaesions in the vicinity of the hypoglossal nerve.
