Frontal tumour crossing the midline

Case contributed by Dr Jeremy Jones


This elderly gentleman presented with altered behaviour and headache.

Patient Data

Age: 70 years
Gender: Male
Modality: CT

Post-contrast imaging demonstrates an intra-axial frontal lesion that crosses the midline. It demonstrates mixed enhancement characteristics with central areas of low attenuation and extensive bilateral frontal vasogenic oedema.

Case Discussion

This CT demonstrates a frontal tumour crossing the midline with significant surrounding vasogenic oedema. It has cystic areas and peripheral enhancement.

The differential is wide and tissue was not acquired.

Initial thoughts were that this represented a butterfly glioma, but the ACA can be seen posterior to the mass meaning that it cannot be within the corpus callosum

This tumour may represent glioblastoma multiforme, although the differential is wide.
