case_images: CT now showed hemorrhagic infarcts in the bilateral high parietal regions [Figure 1]; the infarcts were larger on the left side, with a mass effect and midline shift toward the right [Figure 2]. Contrast-enhanced CT showed hypodense attenuation of the superior sagittal sinus posteriorly with peripheral enhancement (called the empty delta sign), Which was suggestive of sinus thrombosis [Figure 2].

case_images: Initial noncontrast T2-weighted MR image revealed a small hyperintense lesion in the left high parietal region of the brain, predominantly involving the white matter [Figure 3].

case_images: Coronal plane contrast-enhanced T1-weighted image demonstrated a nonenhancing superior sagittal sinus with the empty delta sign [Figure 4].
case_images: Maximum-intensity projection (MIP) MR venography image shows nonvizualization of the anterior portion of the superior sagittal sinus due to thrombosis

case_images: On MR venography there was nonvisualization of the anterior portion of the superior sagittal sinus due to absent flow, confirming the presence of thrombosis [Figure 5].
