A: Coronal, T2-weighted sequence showing a tumor in the left parietal
region with predominance of hyposignal, intermingled with areas of cystic/necrotic
degeneration. B: Axial functional MRI, diffusion-weighted sequence does
not demonstrate areas of hypersignal. C: Axial image, apparent diffusion
coefficient mapping corroborating the absence of areas of diffusion restriction.
D: Contrast-enhanced sagittal T1-weighted sequence showing exuberant
and heterogeneous contrast enhancement.

Due to the cosmetic deformity, the patient sought medical assistance and underwent laboratory tests whose results were normal, and magnetic resonance imaging (MRI) (Figure 1) that demonstrated the presence of a heterogeneous lesion with predominance of iso/hyposignal on T1-weighted, low signal intensity on T2-weighted, foci of signal drop on magnetic susceptibility sequences and absence of diffusion restriction.
