When the MRI showed a T1 hypointense/short-tau inversion recovery hyperintense lesion involving the L4 vertebral body (e.g., including the pedicles and lamina), a CT-guided core needle biopsy was performed to document whether this was a metastatic lesion [Figures 1a and b].

The CT-guided biopsy of the L4 vertebral body was performed under local anesthesia, and the histopathological examination was consistent with metastatic breast carcinoma [Figures 2a-c and 3a-d].
Histopathological images of the computed tomography-guided biopsy from L4 vertebrae, (a) x40 and (b) x20 H and E stained image - showing bony trabeculae infiltrated by neoplastic cells having hyperchromatic nuclei, (c) x40 and (d) x20 immunohistochemistry image - tumor cells show GATA 3 positivity.

When the CT angiography (e.g., CTA) suggested a laceration of the L4 left lumbar segmental artery, the patient underwent immediate transcatheter selective embolization [Figures 5a-d and 6].
