Chordoid glioma in the thalamus of a child: Rare location and atypical imaging findings

摘要

Chordoid glioma is a rare intracranial tumour, which usually occurs in middle-aged female patients, mainly in the third ventricle, hypothalamus and suprasellar region. It can reportedly occur in the temporal–parietal lobe, occipital horn of the lateral ventricle and left thalamus. Here, we report a case of chordoid glioma in the thalamic region of a female child, which is different from the previously reported chordoid glioma in the left thalamus. Given its atypical location and imaging findings, it is often misdiagnosed as low-grade glioma before operation. Through the study of this case, we recognized the atypical imaging manifestations of chordoid glioma in a rare location.
