Figure 4From: Hemorrhage of brain metastasis from non-small cell lung cancer post gefitinib therapy: two case reports and review of the literature Case 2. A: T1-weighted brain MRI shows a metastatic lesion of heterogeneous signal intensities in the left thalamus (arrow). Components of hyper-signal intensities represent subacute hemorrhage. B: This lesion is also of heterogeneous signal intensities on T2-weighted images, with components of hypointense hemosiderins representing chronic hemorrhage (arrow). C: Contrast-enhanced MRI shows inhomogeneous enhancement of the lesion (arrow).Back to article page
