Q; What is cupola sign?
Answer: Cupola sign is visible on the chest or abdominal x-ray and signifies the presence of pneumoperitoneum. "Cupola" is a Latin word and means "little cup".
In a supine patient with pneumoperitoneum when non-dependent air rises up it can be seen as a lucency under the central area of the diaphragm. This lucency makes the lower thoracic vertebral bodies more prominent. This lucency appears as a cup with a well-defined upper border, Lower border of the cup remains unremarkable.
