Description
Summary:Calcifying pseudoneoplasm of the neuroaxis (CAPNON) is a rare, slow growing, and generally benign fibro osseous mass that can emerge throughout the entire central nervous system (CNS). When diagnosed, prompt surgical treatment can determine a good neurological outcome and possibly curative resolution. The objective of the present work is to present a step by step technical report with its video. We present a 37 year old female presented with occipital headache and cervical pain associated with dysphagia, nausea, and gait disturbances. Computed tomography (CT) scan showed a focal calcified lesion on the floor of the IV ventricle projecting toward the vermis with associated supratentorial hydrocephalus and transependymal edema. The telovelar approach was chosen for the procedure. The outcome was favorable, with no complications. Postoperative CT was performed, which revealed no residual lesion. A step by step report of a IV ventricle CAPNON that manifested with hydrocephalus is described.
