Migrating intrathoracic gallstone: imaging findings.

We present the case of a 76-year-old man referred to our hospital with a round stone in central mediastinum and pneumomediastinum in chest radiography and computed tomography. He had a previous history of attempt of endoscopic retrievement of a gallstone that had caused a gastric outlet obstruction (Bouveret syndrome).

[Diagnosis of osteoporosis by lateral chest X-ray].

Background: Lateral chest X-rays may be helpful in the early detection of osteoporotic patients.

Patients And Method: We reviewed both lateral chest X-ray records of 3,500 consecutive patients and their medical records with the ultimate diagnosis.
