Clinical question: Lung cancer. Please evaluate for metastases. Signs and symptoms: Lung cancer. Nonenhanced CT of brain:There is no evidence of intracranial hemorrhage, mass-effect, midline shift or hydrocephalus. Previously noted large area of vasogenic edema in the left frontal lobe under the left frontal craniotomy flap is no longer identified and only residual encephalomalacia is noted. Findings of a small vessel disease of indeterminate age. There is no definitive evidence of metastases lesion on this non-infused exam however to entirely exclude possibility of metastases disease post enhanced CT or MRI is recommended.
