Solitary plasmacytoma of L3 vertebral body treated by minimal access surgery: Common problem different solution!

INTRODUCTION

Solitary plasmacytoma of bone is a local primary bone tumour consisting of malignant plasma cells without systemic involvement. These tumours are known for large amount of blood loss, and the use of electrocautery is helpful in reducing blood loss and performing surgery in a relatively bloodless field; however, use of unipolar cautery in patients with indwelling cardiac pacemaker is known to cause arrhythmias and cardiac events. Minimally invasive techniques offer potential advantages over open techniques particularly in patients with spinal tumours, where massive amount of blood loss is expected, if open procedure is performed. Here, we present a case of solitary L3 plasmacytoma with progressive neurological deficit with chronic refractory anaemia with indwelling cardiac pacemaker treated by minimally invasive technique.

MATERIALS AND

METHODS

A 71-year-old male presented with increasing back pain with Left L3 radiculopathy since 6 months and progressive left lower limb weakness since 5 days. The patient is a known case of chronic renal failure with chronic refractory anaemia. The patient has indwelling cardiac pacemaker for cardiac arrhythmias. Radiology was suggestive of L3 body plasmacytoma. L3 corpectomy and anterior column reconstruction with expandable cage and posterior stabilization by minimally invasive techniques were performed.

RESULTS

Two years of follow-up showed no local recurrence. The patient is ambulatory unaided with no neurological deficit and backache.

DISCUSSION: There is no consensus regarding appropriate surgical approach and perioperative strategies in treatment of solitary plasmacytoma. A solitary plasmacytoma was found in the spine of a patient with cardiac pacemaker where anaesthetic consideration, blood loss and the use of electrocautery were the limiting factors. Minimally invasive approach is a good option.
