We represented a case history of multiple hepatic adenomas in an adolescent with severe clinical course of glycogen storage disease type lb (compound heterozygous mutations c.1042_1043delCT and c.817G>A in the SLC37A4). The patient was prescribed a raw cornstarch and hepatoprotectors therapy, but he and his parents had low compliance to treatment. At the age of 13,5 years ultrasound investigation and computed tomography revealed multiple adenomas. Due to the severe condition of the patient it was impossible to perform focal hepatic biopsy. At present time the patient receives treatment focused on correction of metabolic disturbances, thereafter an applicability of exploratory puncture will be settled for the further patient surveillance. The modern data on causes and risk factors of hepatic adenomas in such patients, the possibility of their malignization, the algorithm of the follow-up and the methods of treatment are presented in the discussion.
