case_images: Preoperative MRI demonstrates a lobulated, cystic mass within the right parietal lobe involving the cortex and the deep white matter, associated with mild mass effect and minimal vasogenic edema. The lesion shows decreased T1 signal without contrast enhancement (a) and increased T2 signal (b, c). The lateral component measures 4.8 x 2.2 cm and medially as 2.2 x 1.4 cm. Global tractography demonstrates probable inferior and medial displacement of the right superior longitudinal fasciculus with some splaying of the fiber tracts along the medial margin of the mass, as well as medial displacement of the right corticospinal tract and mass effect upon the corpus callosum and cingulate (d).

case_images: Brain magnetic resonance imaging (MRI) demonstrated a lobulated cystic mass involving the cortex and underlying white matter of the right parietal lobe, suspicious for a low-grade glial neoplasm (Fig. 1a-c). Diffusion tensor imaging was also performed and demonstrated probable inferior and medial displacement of the right superior longitudinal fasciculus with some splaying of the fiber tracts along the medial margin of the mass; medial displacement of the right corticospinal tract and mass effect upon the corpus callosum and cingulate gyrus was also noted (Fig. 1d).
case_images: a, b Postoperative MRI demonstrates gross total resection of the right parietal mass with expected postoperative changes.
