Papillary glioneuronal tumor presenting with low-pressure hydrocephalus from intraventricular spread: Case Report.

ABSTRACT

Papillary glioneuronal tumors are a rare and typically benign entity with pathological and radiographic complexity. Presentation can mimic other neoplasms, making diagnosis more challenging. The literature to date describes the clinical understanding, diagnostic, therapeutic, and prognostic characteristics of this limited number of patients. In this article, we report an unusual case of a glioneuronal tumor with multifocal presentation, normal pressure hydrocephalus-like symptoms, and large peritumoral parenchymal cysts, which guided the surgical approach. This unusual presentation has not previously been reported and adds valuable information to the clinical recognition and management literature.
