Frontal Balloon Sinuplasty in Complicated Acute Pediatric Rhinosinusitis (ARS)

Figure 1

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.
