Choroid plexus papilloma (CPP) is a rare benign tumor of the central nervous system. Bilateral lateral ventricle CPP is extremely uncommon. In this case report, we described a case of bilateral lateral ventricle CPP in a 4-month-old female patient conceived by in vitro fertilization (IVF). Neurological examination and imaging were performed. In neurological examination, meningeal irritation signs and sunset phenomenon were positive. Brain computed tomography (CT) and magnetic resonance imaging (MRI) displayed masses located in the trigone of the bilateral lateral ventricle with hydrocephalus. Contrast-enhanced MRI showed intense homogeneous enhancement. The diagnoses of bilateral lateral ventricle CPP related to hydrocephalus and extravasation of cerebrospinal fluid (CSF) were made. Repeated surgical procedures via parietotemporal craniotomy were performed, and the diagnosis was confirmed by histopathology examination. The patient presented with delayed development during a follow-up period of 1 year. In conclusion, imaging is an effective approach of investigation. CPP could be highly suspected according to the features of hydrocephalus, lobulated appearance, and homogeneous enhancement on imaging. Total surgical removal is a valid curative method for CPP.
