Giant cell tumour of dorsal spine presenting with mediastinal mass: a rare case report

Abstract

Incidence of giant cell tumour (GCT) of spine above sacrum is rare. Moreover, involvement of posterior elements of spine is a rare entity. Furthermore, primary GCT arising at thoracic spine presenting as a huge mediastinal mass is extremely rare. Here, we are presenting a case of GCT presenting with posterior mediastinal mass. The case came to Orthopaedics outpatient department (OPD) with long-standing pain at the dorsal spine with features of depression. When chest X-ray was done, a posterior mediastinal mass at the level of D10 vertebra was detected. Magnetic resonance imaging (MRI) of the dorsal spine revealed a GCT involving body, left transverse process, and pedicle of the D10 vertebra. Computed tomography (CT)-guided biopsy from the posterior mediastinal mass and D10 vertebra was suggestive of GCT of dorsal spine.
