Summary:

Description	Radiopaedia case ID: 66668 Image ID: 47185822 Image stack position: 34/59 Plane projection: Axial Aux modality: non-contrast Study description: CT Brain Modality: CT System: Central Nervous System Findings: 4.8 cm x 3.2 cm (axial) x 2.9 cm (craniocaudal) heterogenous mass centered in the anterior left temporal lobe. The crescentic peripheral portion of the lesion demonstrates hyperattenuation relative to the remainder of the brain parenchyma on noncontrast study and demonstrates avid enhancement on post-contrast imaging. Low attenuation centrally in the lesion consistent with necrosis. Surrounding vasogenic edema, most pronounced in the left temporal and parietal lobes with associated mass effect, with effacement of the sulcal pattern of the left temporal and parietal lobes, slight effacement of the left basal ganglia, basal cisterns, and of the left lateral ventricle; with minimal (2 mm) left-to-right midline shift. Sclerotic changes noted in the anterior left temporal bone with evidence of transosseous extension of tumor better seen on the MRI.
