Metastatic Mucinous Adenocarcinoma Mimicking Cerebral Hemorrhage

Brain metastases originate most commonly from carcinonoma of lung, breast, and colon and from melanoma. Therefore, metastatic adenocarcinoma to the brain are common metastatic brain tumor. Generally, metastatic adenocarcinoma in the brain appears low density on the non-enhanced computed tomography(CT). However, in very rare case mucin-containing metastatic adenocarcinoma show high density mimicking cerebral hemorrhage. We report a case of metastatic adenocarcinoma to the brain that appeared as a homogeneously hyperdense mass on CT.
