There is a left frontal cortical and sub-cortical mass lesion measuring 28mm x 30 mm x 65 mm involving the left superior frontal gyrus. Within the mass lesion there are punctate foci of heterogeneous calcification, minimal patchy contrast enhancement and no definite restricted diffusion. Spectroscopy demonstrates raised choline and decreased NAA with mildly increased left frontal perfusion (CBV).
No remote intra- or extra-axial mass lesions, acute haemorrhages or collections. No acute infarcts.
Conclusion:
Left frontal mass lesion likely representing a glial series tumour, possibly with oligodendroglial components.
