[Calcified cerebral metastasis].
A hyperdense intraparenchymal lesion on a cerebral computed tomography (CT) usually corresponds to an acute hematoma; however, it is sometimes necessary to rule out a metastatic cause. Focal calcifications in the brain are common and are most often due to granulomas (tuberculosis, cysticercosis...), hamartomas, and primary brain tumors. Cerebral metastases are the most common intracranial neoplasm; however, their rate of calcification in classic series is only approximately 1%. We report the case of a completely calcified cerebral metastasis studied by CT and magnetic resonance imaging (MRI) that was interpreted as acute hemorrhage on the first CT examination.
