a: (Dec. 2012) Axial orbital CT scan shows a heterogeneous intraconal mass lesion with small foci of hyperdensity. MRI T1 scan shows a hyperintense lesion in the posterior part of the left globe that is hypointense in T2 MRI image. b: (Nov. 2013) MRI scan showing the larger left eye and mass outside of the left orbit. (Compare with MRI scan in Fig. 2a). c: (May 2014) CT scans show tumour regression in the left orbit and a small moderately intense mass on the left side of the neck with extension to the parotid and submandibular glands. d: (Dec. 2014) Axial CT scans show attenuation to muscle and an ill-defined solitary mass in the left orbit as well as a very large and moderately intense mass on the left side of the neck with extension to the parotid and submandibular glands. MRI scan shows iso-intensity on T1-weighted images with moderate to marked enhancement post-contrast with fat suppression, hyper-intensity on T2-weighted images in the left orbit and a large mass that was iso-intense on T1-weighted images with moderate to marked enhancement
