Management in chordoid glioma: Avoiding the pitfalls in this rare and challenging entity

Neurol India. 2017 Jul-Aug;65(4):808-813. doi: 10.4103/neuroindia.NI_1008_15.

Abstract

Chordoid glioma (CG) of the third ventricle is an unusual neoplasm of glial nature, which is almost exclusively located in the anterior wall of the third ventricle, in close relation with the hypothalamus. Magnetic resonance images show CG as a suprasellar, hypo- to isointense mass, homogeneously enhancing after the administration of gadolinium. Since its description in 1998 by Brat et al., approximately 85 cases have been reported. Some of its pathological features are under discussion and its histological origin still remains unclear. In this study, we present a patient having this rare entity. We review the management of CG reported in literature. We also studied its pathological features, the postoperative mortality and morbidity related to radical surgical resection, and the implemented adjuvant therapies. Due to its classical clinical features and its close resemblance to other lesions in the region, it is an entity unlikely to be suspected prior to its histological diagnosis. Despite the benign nature of this tumor, the clinical outcome might be poor. Its treatment may represent a real challenge because it involves critical anatomical areas, leading to high postoperative morbidity and mortality rates. An initial minimally invasive management and adjuvant therapies, such as radiosurgery, in case of symptomatic recurrences, can be effective handling strategies.
