A CT scan can be helpful in the diagnosis of splenic torsion.

A pathognomonic CT finding is the whirl appearance of the splenic pedicle (thickened and coiled vascular pedicle).


Less specific findings seen in the CT scan include:

(1) splenomegaly

(2) poor or absent contrast enhancement of splenic parenchyma

(3) hyperdense splenic pedicle on unenhanced scan (a sign of thrombus n a torsed pedicle)

(4) rim sign or pseudo-capsule sign (sign of chronic ischemia)
