A case of Epstein-Barr virus-associated smooth muscle tumor of the posterior interosseous nerve mimicking schwannoma

Ancient schwannoma of the thoracic spine treated with vertebroplasty: A case report

INTRODUCTION

Intraosseous schwannomas or neurilemomas are rare benign neoplasms. Total resection of the intraosseous schwannoma is considered risky in immunocompromised patients, thus minimally invasive vertebroplasty was conducted in this study.

CASE REPORT

In this case, we presented A 40-year-old male presented with intermittent back pain for the last two years. Imaging and histopathological examination conclude the diagnosis of intraosseous schwannoma. Vertebroplasty was conducted without the resection of the tumor. Excellent pain improvement and functional outcome were reported on one-year follow-up.

CLINICAL DISCUSSION

Minimally invasive surgery could decrease post-operative pain and morbidity such as atelectasis and venous thrombosis, earlier hospital discharge, and improved cosmetics. We considered the use of minimally invasive vertebroplasty due to HIV infection comorbidities in the subject. Extensive tumor resection in this population could increase the risks of infection significantly thus affecting the outcome of the surgery. The aim of percutaneous vertebroplasty is to increase the stability of the collapsed vertebra and improve the symptoms, especially with severe back pain.

CONCLUSION

Intraosseous schwannoma of the vertebrae could be treated effectively with vertebroplasty with excellent pain improvement and functional outcome.
