title: Endoscopic resection of calcifying pseudoneoplasm of the neuraxis (CAPNON) of the anterior skull base with sinonasal extension.
abstract: We present a calcifying pseudoneoplasm of the neuraxis (CAPNON) of the anterior skull base that was resected endoscopically. The clinical details are reported with a review of the relevant literature. CAPNON, although rare, should be considered in the differential diagnosis of tumors presenting along the anterior skull base with radiographic characteristics consistent with a fibro-osseous lesion. Endoscopic resection of these lesions is feasible in select patients with sinonasal extension.
