We investigated a 27-year-old woman with a retroauricular tumour. MRI revealed a signal void on T1 and T2-weighted images, and irregular enhancement with gadolinium-DTPA. The underlying dura mater also enhanced. The tumour was resected completely, and histological examination showed a benign osteoblastoma.
