case_images: F1
case_images: This lesion appeared hyperdense on CT scan [Figure 1], a finding that drew the attention to a possible recent intratumoral bleeding.
case_images: T1-weighted images (contrast-enhanced) demonstrating a hyperintense left frontal lobe lesion

case_images: F2
case_images: It was hyperintense on T1-weighted images [Figure 2] and isointense on T2-weighted images.
case_images: Gradient echo sequence: the lesion is isointense to the brain

case_images: But when analyzing the gradient echo sequence (GRE), the lesion was isointense to the brain [Figure 3].
case_images: Histopathologic findings included dense deposit of melanin, intense tumoral necrosis and nuclear atypism with surrounding secondary lesions (H and E, x300)
