Differential diagnosis of a vanishing brain space occupying lesion in a child

Figure 1 Cranial magnetic resonance imaging brain (on admission at September 2009) showing (A, B) sagittal and axial T1-weighted views with a solitary hypointense lesion in the left temporal lobe; (C-E) axial fluid attenuated inversion recovery and T2-weighted (F) images showing hyperintense lesion in the left temporal lobe encroaching on the adjacent brainstem with perifocal edema and mass effect; (G, H) axial and sagittal T1-weighted views showing homogenous solitary enhanced lesion in the left temporal lobe encroaching on the adjacent brainstem and surrounded by a moderate hypointensity.
