Diagnosed with appendicitis. Post laparoscopic surgery x-ray was advised.

Patient Data

Age: 20
Gender: Male
Modality: X-ray

Radiolucent area noted below the diaphragm across the abdomen

This is gas under the diaphragm

Modality: Annotated image

Gas under diaphragm indicated by yellow arrows. This is referred to as continuous diaphragm sign.

Case Discussion

This is a case of pneumoperitoneum post laparoscopy, which can be a "normal" (i.e. expected) finding if the volume of gas is appropriate. 

Normally on a chest xray two hemidiaphragms are demonstrated but in cases of a pneumoperitoneum the entire continuity can be seen.
