A diffuse-type giant cell tumor (DGCT) of the paravertebral region is a rare condition characterized by an ill-demarcated mass with facet joint involvement. We describe a case of extra-articular DGCT of the paravertebral cervical region without association to the facet joint. A 51-year-old male presented with a headache. Diagnostic imaging showed a dumbbell-shaped mass with enlargement of the right intervertebral foramen between C6 and C7. The tumor was completely resected in multiple fragments with the suspicion that it was a schwannoma. Histologically the tumor consisted chiefly of mononuclear histiocytoid cells, foamy macrophages and multinucleated giant cells, which led to a diagnosis of DGCT. The case alerts one to be aware that DGCT may originate from a paravertebral location as a soft-tissue mass without facet joint involvement.
