Bone remodeling in sigmoid sinus diverticulum after stenting for transverse sinus stenosis in pulsatile tinnitus: A case report

Figure 1 Dynamic changes of the sigmoid sinus wall on computed tomography venography. A: Preoperative image; B: Image on the second day after surgery; C: Compared to A and B, a decrease in the sigmoid sinus diverticulum (orange arrow) with new bone remodeling (orange arrowhead) was observed on the image obtained 6 mo after surgery; D: The density of the remodeled bone was increased on the image obtained one year after surgery; E: The formation of a hardened remodeled edge was observed on the image obtained 2 years after surgery. Sigmoid sinus wall dehiscence (white arrow) revealed no changes on the computed tomography images obtained at various time points.
