title: Chronic diploic hematoma mimicking malignancy on imaging.
abstract: We present a case of an expansile diploic lesion involving the parietal bones in a 45-year-old man. Computed tomography, magnetic resonance imaging, and digital subtraction angiography were performed. The imaging findings strongly suggested the diagnosis of a malignant neoplasm. Nonetheless, histology revealed a chronic diploic hematoma.
