Summary:

Description
  • Radiopaedia case ID: 49984
  • Image ID: 27011556
  • Image stack position: 3/22
  • Plane projection: Axial
  • Aux modality: T1 C+
  • Study description: MRI Brain (3 months later)
  • Study findings: Expansile T2 hyperintense mass involves the left anteromedial temporal lobe, insular, basal ganglia and corona radiata, as well as the left thalamus. Better appreciated on the T2 than the flair sequences, there is also hyperintensity in the medial right temporal lobe which is consistent with contralateral spread of tumor along unexpanded rostrum of corpus callosum. There are 2 separate regions of focal enhancement, in the anterior aspect of the basal ganglia and in the left posterior insula, both with corresponding high-grade features of elevated cerebral blood volume and ADC reduction. The degree of expansion related to the tumor has slightly increased and the two nodular enhancing foci are new.
  • Modality: MRI
  • System: Central Nervous System
  • Findings: Ill-defined hypoattenuating mass involving the left mesial temporal lobe, anterior temporal lobe, basal ganglia, and insula. Local mass effect is seen with gyri effacement, compression over the left lateral ventricle, and mild rightward midline shift. Focal ill-defined wispy enhancement noted within the insular cortex. No calcification or signs of acute hemorrhage.
