A 7- year- old, male canine was referred with apathy and anorexia from last four days. Radiography revealed splenomegaly and ultrasound showed a "lacy parenchyma" with "hyperechoic perivenous" triangle. A tentative diagnosis of splenic torsion was made. The CT examination was performed for special reconstructions and to obtain additional information to confirm the diagnosis. Images in an oblique plane transversal to the splenic arteries and veins were reconstructed. Looking at these images in a fast forward video mode, the rotated pedicle, containing the splenic vessels along the gastrosplenic ligament, surrounded by the twisted, striated, hyperattenuating fat had a striking resemblance to a meteorological satellite video of a tornado. The "Tornado sign" is a characteristic, possibly pathognomonic sign of splenic torsion. Splenic torsion was than confirmed on exploratory laparotomy. The dog recovered completely with supportive care. In conclusion, if torsion of an organ is suspected and computed tomographic images in standard planes fail to demonstrate and identify the rotation, images perpendicular to the pedicle and/or main mesenteric or hilar vessels supplying the organ should be reconstructed and evaluated in a fast forward video mode as an additional diagnostic tool.
