En-bloc resection of a giant cell tumor causing cervical vertebral collapse

Giant cell tumors (GCTs) are rare, benign, and locally aggressive primary bone neoplasms. Spine is seldom affected, especially above the level of sacrum. In this report, we describe a case with GCT of the cervical vertebrae which causes collapse of the corpus. A 32-year-old female presented with gradual neck pain and abrupt paresthesia of the left hand. Computed tomography scan showed C6 vertebral collapse and magnetic resonance imaging demonstrated vertebral plana of C6 by a low signal intensity lesion on T1- and T2-weighted images. Emergent surgical intervention was taken due to the possibility of spinal injury. The tumor was removed by en-bloc resection and histopathological investigation confirmed GCT. In most of the cases, en-bloc resection of GCTs of the spine is not feasible. Despite the location and close contact of the lesion with spinal cord, later approach was successful for our case; thus, appropriate differential diagnosis for vertebral column lesions as well as selecting an optimum treatment is mandatory.
