[The empty delta sign. A useful or misleading sign in cerebral x-ray computed tomography?].
One case of bifidity of the superior sagittal sinus, resulting in a false "empty delta sign", is presented. The authors emphasize the importance of the indirect signs of sinovenous thrombosis, i.e. cerebral edema and multiple or bilateral hemorrhagic infarcts, in the diagnosis of true empty delta sign.
