Fibrohistiocytoma combined with an aneurysmal bone cyst at T7 in a 63-year-old woman.

We present a case of spinal tumor, with fibrohistiocytoma combined with aneurysmal bone cyst (ABC) at the pedicle and transverse process of T7 in a 63-year-old female. ABC is a rare skeletal tumor and spinal ABC is extremely rare. Fibrohistiocytoma is a type of primary benign bone tumor. ABC is also a rare bone tumor that most often occurs in the pelvis. The combined lesion of two primary bone benign tumors is relatively rare in clinic. In addition, fibrohistiocytoma and ABC are widely confused with other giant cell containing tumors of the bone. X-rays, magnetic resonance imaging (MRI) and positron emission tomography-computed tomography (PET-CT) scans were performed and assessed. Finally, the diagnosis was confirmed by pathological tests. The patient underwent surgery and had an extremely good recovery. The correct diagnosis of a spine tumor is important when determining the surgical procedure.
