Case contributed by Dr Maulik S Patel


Acute abdominal pain for 12 hrs. Referred for ultrasound.

Patient Data

Age: 20 yrs
Gender: Male

Without compression, there is uniform acoustic shadowing at the interface deep to the inner abdominal wall. With compression, this disappears.

This is compatible with pneumoperitoneum blocking the sound beam which resolves when it is pressed out of the way.


Free intra-abdominal gas under the diaphragm.
