- Fig 1.
A 58-year-old woman with a history of index finger chondrosarcoma and a right frontal bone mass. Axial CT (A) and FDG-PET/CT (B) images show an aggressive permeative and hypermetabolic bone marrow–replacing lesion in the right frontal bone with an aggressive periosteal reaction (A and B, arrow). Axial CT image during percutaneous biopsy (C) shows positioning of a coaxial bone-biopsy needle within the lesion. The total conscious sedation time was 29 minutes, and histologic evaluation confirmed intraosseous meningioma.

A 65-year-old man with poorly differentiated salivary gland sarcomatoid carcinoma with a left temporal bone lesion. Axial T1-weighted MR imaging (A), CT (B), and technetium 99m methylene diphosphonate SPECT-CT (C) images show an osteolytic bone marrow–replacing lesion with increased radiopharmaceutical uptake in the petrous portion of the left temporal bone (A–C, arrow). Note the surrounding vital tissues. Coronal CT image (D) during percutaneous biopsy shows coaxial positioning of a soft-tissue biopsy needle, through an OnControl bone introducer cannula, within the lesion through the mastoid air cells. The total conscious sedation time was 40 minutes, and histologic evaluation confirmed metastasis from a known primary salivary gland tumor.
