Abstract:
Objectives: The report aims to inform the reader of cases of inverted papilloma involving the frontal sinus presenting with a unique radiological finding.
Study Design: Case series.
Methods: A retrospective medical record analysis was carried out to identify patients with inverted papilloma of the frontal sinus and a serpiginous pattern of neoosteogenesis on CT scan. Clinical records, including initial history, radiologic studies, and operative findings were carefully examined.
Results: Three patients with inverted papilloma in the frontal sinus presenting with a serpiginous pattern of hyperostosis on radiologic assessment were identified. All patients had these “bony islands” findings on CT as well as complete opacification of bilateral frontal sinuses and frontal recesses. All patients had biopsy-proven inverted papilloma and underwent endoscopic resection.
Conclusions: A serpiginous pattern of hyperostosis on CT is an unusual radiological finding of inverted papilloma of the frontal sinus. To date, this rare imaging pattern has not been described in the literature. Identification of these bony formations on imaging should raise suspicion for the diagnosis.
