Left thalamopeduncular cystic and solid pilocytic astrocytoma. A: A coronal FLAIR MR image demonstrating that the tumor grows from the thalamopeduncular junction, across the ambient cistern, and through the choroidal fissure of the temporal horn of the lateral ventricle to invade the middle fossa. B: Coronal DT images showing that the CSTs are displaced medial to the tumor. Medial tract displacement made an image-guided approach through the middle temporal gyrus optimal to reach both the superior and inferior extent of the neoplasm. C: A coronal T2-weighted MR image obtained the day after surgery, demonstrating the approach through the temporal lobe and a gross-total resection of the tumor, sparing the CSTs.
