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)
