Abstract
Myasthenia gravis is an autoimmune disease, the clinical manifestations of which are in the form of weakness and pathological muscle fatigue. We present the clinical case of a patient with predominantly lingual muscle involvement. The patient was diagnosed with a generalized 2A–2B form of myasthenia gravis. Dysarthria and weakness of the masticatory muscles were observed at the onset of the disease. The diagnosis was established 1.5 months after the appearance of the first complaints. Diagnosis at the outpatient stage was hampered by the epidemiological history and the short duration of symptoms that occurred only after eating. All of the above determines the importance of clinician`s alertness about the possibility of this disease manifesting itself in such a rather specific and rare group of symptoms.
