Figure 1: (a) Axial image of plain CT scan reveals a hyperdense lesion in the left frontal lobe; (b) T2 fast spin echo axial and (c) Fluid Attenuated Inversion Recovery (FLAIR) coronal MR images showing homogenously decreased T2 signal; (d) DWI does not reveal restricted diffusion; (e) T1-weighted axial MRI without contrast shows the lesion with homogenously increased T1 signal; (f) T1-weighted axial MRI with contrast shows no significant enhancement in the cyst. The focal T2 hypointense nodule anteriorly shows heterogeneous contrast enhancement and corresponded to granulation tissue on histopathology (White arrow in b, e and f)
