Choroid Plexus Papillomas (CPPs) are rare tumors of the central nervous system, typically benign but necessitating surgical intervention. We present the case of a six-month-old female infant with signs of intracranial hypertension, diagnosed with tetra ventricular hydrocephalus and a left intraventricular mass. Emergency ventriculoperitoneal shunt valve placement was followed by brain MRI revealing a multilobulated hypodense intraventricular mass with homogeneous contrast enhancement. The patient underwent total excision of the lesion aided by intraoperative ultrasound, resulting in uneventful postoperative recovery. CPPs present unique challenges due to their vascularity and localization. Intraoperative ultrasound guidance proves invaluable in distinguishing pathological tissue, enhancing resection rates, and improving overall surgical outcomes. This case highlights the efficacy of intraoperative ultrasound in CPP management, underscoring its role as a valuable adjunct in neurosurgical practice.
