Solitary bone plasmacytoma of the upper cervical spine: A case report

Figure 1 Laboratory examinations. A and B: C2 biopsy showed multilobe mature plasma cells with no histological pathologies; C: No tumor cells were found in the bone marrow 1 year postoperatively.

Figure 2 Sagittal X-ray. A: Mild cervical kyphosis and cystic lesions in the C2; B and C: Sagittal and plain computed tomography scan revealed bone destruction in the pedicle of C2. The posterior wall of the vertebrae was destroyed.

Figure 3 Magnetic resonance imaging. A: A high signal mass on the right side of C2 with an irregular boundary; B: Cervical disc herniation could be found in C4-6, while no garrulous blade or swollen discs were observed toward the spinal cord in C2.

Figure 4 Single photon emission computed tomography/computed tomography showed high bright signal in the C2 and teeth.

Figure 5 Postoperative X-rays and computed tomography showed that the bone cement filled well, and no leakage occurred during 3 years of follow-up. A and B: The anteroposterior and lateral X-ray was taken at 2 d after surgery; C and D: The two sagittal computed tomography scans were taken at 6 mo and 3 yr after surgery. They showed that no leakage of the bone cement occurred, and the shape of the C2 was maintained.
