Low-grade astrocytoma

Case contributed by A.Prof Frank Gaillard


Previously well, today had a seizure but has now fully recovered.

Patient Data

Age: 35 years
Gender: Male

Pre and post contrast CT of the brain demonstrates are relatively well circumscribed region of low attenuation centered immediately deep to the anterior part of the right insular cortex, displacing the lentiform nucleus posteromedially. There is no evidence of hemorrhage and no convincing contrast enhancement. Despite its large size it exerts little mass effect. The rest of the brain is unremarkable. 

Case Discussion

Many low grade astrocytomas are strikingly hypo-attenuating and can appear very large with relatively little mass effect on account of their infiltrative nature and slow growth.
