New Observations on a Low-Grade Diffusely Infiltrative Tumour, SMARCB1 Mutant, Arguing for a New Tumour Type.
This report details two cases of low-grade diffusely infiltrative tumour (LGDIT) in an 18-year-old and a 50-year-old male, both presenting with supratentorial lesions.
Clinical pearl
Clinicians should recognize the distinct histological and genetic features of low-grade diffusely infiltrative tumours, particularly the significance of SMARCB1 mutations and INI1 loss in diagnosis.
