title: Unusual appearance of an intracranial metastatic adenoid cystic carcinoma: comedo-necrosis showed very hyperdense nodules on CT scans.
abstract: A case of intracranial metastatic adenoid cystic carcinoma with unusual hyperdense nodules in CT scans is described. A 32-year-old man had a brain tumor containing scattered and very hyperdense numerous nodules on CT scans. Initially, the hyperdense nodules were considered as intratumoral calcifications. The tumor subsequently proved to be metastatic adenoid cystic carcinoma through surgery. However, there were no calcium deposits in the surgical specimen. We observed only multiple central comedo-necrosis that could be the cause of the hyperdense lesions on CT scans.
