Giant cell tumor of dorsal vertebral body

Abstract

A 30-year-old female patient presented with complaints of backache, weakness in both lower limbs and bladder/bowel dysfunction. Imaging showed an osteolytic lesion at tenth dorsal (D10) vertebra with anterior compression on the spinal cord. Complete intralesional tumor excision with reconstruction was carried out using the anterolateral extrapleural approach. Histopathological examination was suggestive of giant cell tumor (GCT). Because of complete intralesional tumor excision and fear of post-radiation osteonecrosis of bone used for delayed bony union, a conservative approach was used, and radiation therapy was not given. After one year of follow-up patient is doing well without any recurrence of the tumor and is ambulant with support. GCT of dorsal vertebral body is an uncommon entity and total en bloc excision is difficult. Therefore, the treatment strategy is not well-defined. We discuss in brief about incidence, presentation and various treatment modalities available for spinal GCT.
