A 2.5 x 3 cm (axial plane) left temporal lobe poorly marginated, hypodense lesion is seen and demonstrates a contrast enhancing rim.
The periphery of the lesion appears to extend into the left frontal lobe superiorly. A further 5mm rim contrast enhancing focus is shown in the left frontal lobe further superiorly.
Extensive surrounding vasogenic oedema results in sulci effacement, effacement of the left Sylvan fissure and of the ventricular system. Associated 8 mm right sided midline shift.
In the posterior fossa, there is a 35 x 30 mm retrocerebellar hypodensity shown most consistent with an arachnoid cyst.
No other intra or extra axial mass, collection or acute focal abnormality is identified.
No suspicious bony lesion.
Left temporal poorly marginated, hypodense and rim contrast enhancing lesion is thought most in keeping with a high grade astrocytoma. Extensive surrounding vasogenic oedema.
Retrocerebellar arachnoid cyst.
