Consensus guidelines for the management of primary supra-tentorial intraventricular tumour for low- and middle-income countries

Abstract

Almost any primary or metastatic brain tumour can
manifest in intraventricular (IV) locations. These tumours
may either originate within the ventricular system or
extend into the IV space through growth. Such neoplasms
represent a broad spectrum, with supratentorial IV
tumours forming a heterogeneous group. This group
includes primary ependymal tumours, central
neurocytomas, choroid plexus tumours, and notably,
meningiomas, as well as a variety of non-neoplastic,
benign, glial, and metastatic lesions that can secondarily
invade the IV compartment. Often presenting with nonspecific
symptoms, these tumours can lead to delayed
medical attention. The diversity in potential diagnoses,
combined with their deep and complex locations, poses
significant management challenges. This paper aims to
delineate optimal management strategies, underscoring
the importance of multidisciplinary care, especially in
settings with limited resources, to effectively navigate the
complexities associated with treating intraventricular
brain tumours.
