Barium retention is a rare complication of upper gastrointestinal tract examination when using barium sulphate as a contrast agent. We present a case of rare barium retention and precipitation in the stomach in terrain of chronic gastrostasis and the review of literature on complications of barium sulphate administration. A 38-year-old patient was diagnosed with benign pylorostenosis.

Papillary Thyroid Carcinoma: Analysis of the Central Compartment's Lymph Nodes Metastases.
