T1-weighted images heterogeneous predominantly solid (iso-intense) cystic with central hypo-intense core suggestive of necrosis [Figure 1]. T2-weighted images showed, solid (iso-intense) cystic (hyper-intense) with hyper-intense central core suggestive of necrosis [Figure 1].
Contrast-enhanced MRI in all three planes. (a) Axial images exhibiting heterogeneous enhancement with DTS (open arrow). (b) Coronal images: parasagittal location with DTS (open arrow). (c) Sagittal images demonstrating DTS (open arrow)
