Excessive perihematomal edema in a patient with hemorrhagic lung metastasis
Excessive perihematomal edema in a patient with hemorrhagic lung metastasis
Noncontrast head CT showing left frontal ICH surrounded by excessive volume of hypodense vasogenic edema (A, B). MRI performed one day later shows hyperintense vasogenic edema on T2*-weighted gradient echo image (C). Pre- (D) and post-contrast (E) T1-weighted MRI images demonstrate enhancement (arrows) consistent with underlying tumor.
CT: computed tomography; ICH: intracerebral hemorrhage; MRI: magnetic resonance imaging.
