Abstract

Intracranial metastases represent 7-17% of all brain tumors. Renal cell carcinoma, thyroid cancer, choriocarcinoma, melanoma, retinoblastoma, lung cancer and breast cancer have a propensity for producing hemorrhagic brain metastases. Leukemias have also been rarely reported to cause hemorrhagic brain metastases. We describe an 18-year-old girl diagnosed as acute lymphoblastic leukemia presenting with multiple hemorrhagic brain metastases. MRI demonstrated high signal intensity lesions on both T1- and T2-weighted images which were characteristic for extracellular methemoglobin and consistent with hemorrhagic metastases.
