Perioperative mortality of metastatic spinal disease with unknown primary: A case report and review of literature

Figure 1 Representative axial computed tomography images of the seventh thoracic vertebra. A-C: A destructive lesion involving the T7 vertebral body and right pedicle was observed.

Figure 2 Representative positron emission tomography-computed tomography images of the patient. A and B: Positron emission tomography-computed tomography (PET-CT) imaging of the seventh thoracic lesion. Its maximal standard uptake value (SUV) was 16.74; C: PET-CT scan of the left pulmonary mass (maximal SUV, 4.95).

Figure 3 Pathological examinations of the patient. A and B: Representative image of computed tomography-guided needle biopsy and the corresponding hematoxylin-eosin (H&E) staining result (magnification × 100); C: Postoperative H&E staining of the surgically removed tumor (magnification × 200).
