Situs inversus totalis

Case contributed by Dr Sanjay Karamsadkar


Chest and abdominal pain with clinical suspicion of gastrointestinal perforation/obstruction.

Patient Data

Age: 30 years
Gender: Male

Chest x-ray (PA view):

Dextrocardia and right-sided aorta are demonstrated. The stomach bubble is seen in the right upper abdominal region. 

Abdominal x-ray:

Situs inversus of the abdominal viscera as evidenced by a triangular soft tissue mass (liver) in the left upper quadrant. 

Annotated image

The liver edge is clearly visible (solid white line) with the left kidney adjacent to it. Left sided hepatic flexure of colon (asterisk) is noted.

Case Discussion

Confirmation was sought from the radiographer to ensure that the radiograph images were not erroneously flipped during processing and the marker was not placed on the incorrect side.

This case highlights key abdominal structures that one should aim to identify when interpreting radiographs to avoid confusing anatomical variants with pathology. This is particularly useful in the absence of an associated chest radiograph which may demonstrate an obvious dextrocardia or in the case of incomplete situs inversus.
