Imaging findings before and after balloon dilation. (a)-(c) Preoperative head CT slices with contrast of one case included in the study: (a) fluid-density opacification of the frontal sinus; (b) contrast-enhancing subperiosteal fluid collection overlying the frontal bone, consistent with Pott's puffy tumor; (b)-(c) contrast-enhancing intracranial fluid collection consistent with epidural abscess. (d) T2 MRI six weeks after surgery revealing resolution of abscesses and aeration of the frontal sinus.

Figure 1 shows representative imaging before and after balloon dilation of one case included in the study. Figures 1(a)-1(c) show three frames from a preoperative head CT that highlights multiple potential complications of pediatric ARS patients with intracranial complications including fluid-density opacification of the frontal sinus (Figure 1(a)), subperiosteal fluid collection overlying the frontal bone consistent with Pott's puffy tumor (Figure 1(b)), and epidural abscess (Figures 1(b) and 1(c)). In this case, MRI six weeks after surgery demonstrates resolution of the abscesses and aeration of the frontal sinus (Figure 1(d)).
