Symptoms vary based on location and regional mass effect; however, hydrocephalus is common due to cerebrospinal fluid flow obstruction and\/or overproduction. Distant site metastasis or <jats:italic>de novo<\/jats:italic> formation in extraventricular sites is rare.<\/jats:p>\n<\/jats:sec>\n<jats:sec id=\"st2\">\n<jats:title>Case Description: <\/jats:title>\n<jats:p>A 57-year-old female with a history of a 4<jats:sup>th<\/jats:sup> ventricular CPP status post resection in 2004 and 2018 with subsequent gamma knife therapy in 2019 presented with increased thirst and urination. Since her initial surgery, she has experienced significant gait imbalance, diplopia, dysphagia, and right-sided hemiparesis and hemisensory loss. Magnetic resonance imaging revealed a new 1.5 \u00d7 1.8 cm suprasellar lesion. She underwent a left supraorbital craniotomy for tumor resection, with pathology revealing metastatic World Health Organization grade II CPP.<\/jats:p>\n<\/jats:sec>\n<jats:sec id=\"st3\">\n<jats:title>Conclusion: <\/jats:title>\n<jats:p>Extraventricular manifestation of CPP is rare. <jats:italic>De novo<\/jats:italic> or metastatic involvement of the sella has seldom been reported. Treatment should target gross total surgical resection.
