Figure 1
Figure 1 Cranial computed tomography scan showed a mixed-density lesion in the midline of the posterior fossa (arrow), with a fat-density area inside and calcified margin (arrow), as well as lipid droplet drifts in sulci, cisterns, and lateral ventricles (arrows).
Figure 2
Figure 2 Cranial magnetic resonance imaging at 2 wk after injury. A: The lesion presented hyperintensity on axial T2-weighted imaging (arrow); B: The lesion presented hyperintensity on diffusion weighted imaging (arrow); C: The lesion presented hypointensity on T1-fluid attenuated inversion recovery (FLAIR) (arrow); D: The lesion presented hypointensity on T2-FLAIR (arrow); E: No enhancement in the cystic lesion area was observed on axial T1-FLAIR (arrow); F: On the enhanced sagittal T1-FLAIR, no enhancement was observed in the cystic lesion, while the fat area presented hyperintensity and extended to the subarachnoid space (arrow).
