Objective. Pancreatic insulinoma is often erroneously recognised at first in cases of epilepsy. Diagnostic difficulties are presented in a patient with consciousness disturbances in the course of insulinoma of the pancreas.
Case. A 30-year-old patient with an aortic valve grafted a year earlier, sufferedfrom fits of quantitative and qualitative consciousness disturbances. During his psychiatric hospitalisation insulinoma was hypothesized to be the cause of his disorders. The hypothesis was confirmed by subsequent diagnostic procedures including endoscopy performed at an internal diseases department.
Commentary. In order to reduce the time between the onset of the first symptom and the appropriate diagnosis of the disease it is important to early and carefully differentiate between hypoglycaemia symptoms, including neuroglycopenia.
