The radiological findings of chordoid glioma: report of two cases, one case with MR spectroscopy.
Chordoid glioma is a rare tumor that often originate from the third ventricle. We reported two cases of choroid glioma. Although calcification is a rare findings, dot-like calcification was present on one case. On contrast images, one case demonstrated strong, homogeneous enhancement. On MR spectroscopy (MRS) images, the tumor showed high choline (Cho), low N-acetyl aspartate (NAA) and Cho/Cr=2.38, NAA/Cr=1.19, NAA/Cr=1.19. This might mimic a low-grade tumour. MRS offers additional information and facilitate differential diagnosis for chordoid glioma.
