There is an intra-axial mass lesion involving the right posterior frontal lobe just superior to the Sylvian fissure.
The lesion has a more discrete cortical and sub-cortical component that measures 29mm x 24mm, demonstrating faint enhancement, however, more extensive T2 and FLAIR high signal is noted involving the right frontal opercular lobe, right insula region, right frontal corona radiata, right internal capsule (posterior limb) and body of the corpus callosum.
The abnormal signal within the corona radiata demonstrates restricted diffusion. There is subsequently 9.6 mm left-sided midline shift with effacement of the right lateral ventricle.
No definite imaging abnormality of the ocular globes currently demonstrated.
There is a mass lesion involving the right frontal lobe with a more discrete cortical and sub-cortical component above the Sylvian fissure and a more infiltrative component extending to the right frontal corona radiata and corpus callosum - as detailed above.The imaging findings are not consistent with an abscess.
Likely differentials to consider include an intermediate grade glial series tumour and lymphoma (in view of the restricted diffusion involving the corona radiata).
