Abstract
Malignant peripheral nerve sheath tumors (MPNSTs) of bone are rare. It is mainly located in the appendicular skeleton. The lung is the most common site of metastasis. Solitary lymph node metastasis is very rare. Herein, we report the imaging findings of MPNST in the first thoracic vertebra with lymph node metastasis in the left axillary region. On FDG PET/CT, these lesions had intense FDG uptake. This case highlights that solitary lytic thoracic vertebral lesion with intense FDG accumulation should regard MPNST as a differential diagnosis and that FDG PET/CT has an important role in the initial staging of MPNST.
