Noncontrast computed tomography (CT) scan axial (A), coronal (B) and sagittal (C) planes displaying increased attenuation along the anterosuperior aspect of the superior sagittal sinus (orange arrows) and adjacent cortical veins bilaterally (green arrows) suggesting focal superior sagittal sinus and adjacent cortical veins thrombosis.

Head noncontrast computed tomography (CT) scan displayed increased attenuation along the anterosuperior aspect of the superior sagittal sinus and adjacent cortical veins bilaterally (Figure 1) suggesting focal superior sagittal sinus and adjacent cortical veins thrombosis.
Computed tomography (CT) and magnetic resonance (MR) venogram scans. CT venogram axial (A) and sagittal (B) planes showing nonopacification of the anterosuperior aspect of the superior sagittal sinus (orange arrows) and adjacent cortical veins (green arrows) confirming their thrombosis. MR venogram (C) and MR sagittal (D) T1W-Fat sat postcontrast demonstrate filling defects within the anterosuperior aspect of the superior sagittal sinus (orange arrows).

CT and magnetic resonance (MR) venograms (Figure 2). Coagulation profile showed normal PT/PTT/INR (prothrombin time/partial thromboplastin time/international normalized ratio) and elevated D-dimer.
Follow-up magnetic resonance (MR) venogram (A) MR axial (B) and sagittal (C) T1W-Fat sat postcontrast images demonstrate recanalization of the superior sagittal sinus and the adjacent cortical veins with no sizeable filling defects.

MR and MRV demonstrated evidence of recanalization of the previously noted thrombosed portion of the superior sagittal sinus and adjacent cortical veins (Figure 3). Moreover, a follow-up thyroid function test turned out to be normal.
