<s>[INST] I had a ct scan done last night .And they are saying an 8mm hypodense area in the left frontal white matter of of uncertain etiology . Can you tell me what u think it could be they want me to get a mri done also and i do not have money to pay but will you please answer ... thank you teresa england [/INST] Hello Thanks for writing to usSmall hypodense area may be due to gliotic changes.This condition doesn't need any treatment.It is important to know your age,clinical features,history of trauma etc.Infective etiology is unlikely sine edema is not mentioned in the report.You are rightly suggested for MRI scan.It is important to exclude other conditions like brain cyst etc.Get well soon. Take Care </s>
