Contiguous Multilevel Vertebral Metastasis in Carcinoma Breast Mimicking Spondylodiscitis

A 59-year old female presented with a lump in the right breast for 6 months. She developed progressively increasing backache for 3 months. Magnetic resonance imaging spine was suggestive of hypointense heterogeneous signal intensity in multiple dorsal vertebrae (D3-D8) and suggestive of Pott's spine. Sonomammography suggested a lesion with irregular margin in the retro-areolar region. Fine-needle aspiration cytology was infiltrating duct carcinoma. Fluorodeoxyglucose (FDG) positron-emission tomography-computed tomography revealed mass in the right breast with axillary lymph node. FDG-avid lytic destructive contiguous lesion was noted in mid-dorsal vertebrae. Apart from it, FDG-avid lytic lesion was also noted in the right iliac bone. The patient underwent vertebral lesion biopsy consistent with metastatic breast carcinoma. This case report demonstrates rare contiguous involvement of multiple vertebrae masquerading Pott's spine.
