SUMMARY
AbstractCareful inspection of the infradiaphragmatic area on chest radiographs may lead to diagnosis of different conditions such as gastric fundal masses, sub-diaphragmatic free air, subphrenic abscess, bowel obstruction, etc. Case histories are presented for 4 patients in whom the diagnosis of a gastric tumour was made on chest X-ray. The importance of including the infradiaphragmatic area as a review area of the chest X-ray is emphasised.
