Plasmacytoma of Dens as a cause of Atlanto-axial instability

Abstract

A case of Plasmacytoma of dens (Odontoid Process) in an adult male managed by trans-oral excision and posterior fusion is reported for its rarity. The importance of neuro-imaging and the treatment options, in view of the associated instability at the atlanto-axial region and the diculty in preoperative diagnosis are emphasized.

Primary amyloidoma of the axis and acute spinal cord compression: a case report

“…There are a number of reports describing primary amyloidoma of the spine [1,2,3,4,5,6,8,11,12,14,15,17,18,19,21,23,28] but, to our knowledge, only four cases of primary upper cervical spine amyloidoma (including ours) have been reported (Table 1). The duration of symptoms may be extremely long (up to 6 years) but clinical deterioration may be rapid and severe.…”

“…Inflammatory diseases, bone soft tissue metastasis or plasmocytoma [23] and pyogenic or tuberculosis abscesses [24] are the most frequent causes. Primary tumors, e.g.…”

“…Primary amyloidoma of the axis and acute spinal cord compression: a case report much more rare [1,2,3,4,5,6,8,11,12,14,15,17,18,19,21,23,28].…”

Plasmacytoma of the atlas presenting as hoarseness: a rare cause of unilateral vocal fold palsy

“…In the cervical spine, it has been described in the odontoid process, the second, third and sixth vertebrae, and the cervical dura. [3][4][5][6][7][8] There has been one previous report of bony plasmacytoma occurring in the atlas, but the presentation was one of occipital headaches, difficulty with cranial movements and hyperactive deep tendon reflexes.…”

“…It is often found in the spine without other evidence of multiple myeloma, 2 often causing a lytic lesion within the body of a vertebra (usually thoracic), and can cause compression of the spinal cord. In the cervical spine, it has been described in the odontoid process, the second, third and sixth vertebrae, and the cervical dura 3 8 …”
