A Rare Location of Polymorphous Low-Grade Neuroepithelial Tumor of the Young (PLNTY) of the Thalamus: A Case Report and Review of Literature

Polymorphous low-grade neuroepithelial tumor of the young (PLNTY) is a rare CNS WHO Grade I brain tumor that typically affects children and young adults and may be associated with seizures. Thalamic involvement is exceedingly rare. We report a case of a 29-year-old male with persistent paresthesias in the right upper and lower limbs and suspected sensory seizures. Imaging revealed a left thalamic space-occupying lesion. Stereotactic biopsy confirmed PLNTY. The case highlights the rare presentation of PLNTY in an unusual location and in an adult, emphasising the need for accurate pathological diagnosis in atypical presentations.
