An intra-axial mixed cystic solid tumour centred in the right frontal pole measuring 7.7 cm in maximum diameter is demonstrated. A macrocystic component extends into the right frontal horn and abuts the septum pellucidum. Multiple smaller cysts embeded in a solid component involves the right rectus gyrus cortex.
Multiple septae and a thick cord of enhancement are detected. The mass causes subfalcine herniation with midline shift to the left of 1.6 cm. The anterior cerebral arteries abut the lesion and are displaced to the left. Left temporal horn dilatation keeping with obstruction at the level of the foramen of Munro. The third ventricle is effaced.
There is surrounding oedema.No diffusion restriction detected within the mass lesion. No remodelling of the overlying skull.No susceptibility artefact to suggest calcification or blood products.
