Giant cell tumors (GCTs) are usually found in the epiphysis of the long bones, and represent ~5% of all bone tumors. Only <1% of GCTs are localized in the cranium. When localized in the cranium, GCTs are commonly observed in the sphenoid or temporal bones, and rarely in the parietal or frontal bones. Occipital bone posterior fossa involvement is an extremely rare occurrence. The current study presents a 22-year-old female patient was admitted to the Department of Radiation Oncology (Karadeniz Technical University, Faculty of Medicine, Trabzon, Turkey) with complaints of neck pain and headache. The patients cranial magnetic resonance images showed a 2.5 6-cm mass in the occipital bone, which was subtotally excised. The patient was treated with radiotherapy following the surgery. At present, the patient has shown no progression after 20 months of follow-up.
骨巨细胞瘤（GCTs）通常发生于长骨的骨骺，约占所有骨肿瘤的5%。仅有不到1%的骨巨细胞瘤发生于颅骨。当发生于颅骨时，骨巨细胞瘤常见于蝶骨或颞骨，很少见于顶骨或额骨。枕骨后颅窝受累极为罕见。本研究报告了一名22岁女性患者，因颈部疼痛和头痛入住放射肿瘤学系（土耳其特拉布宗，黑海技术大学医学院）。患者的头颅磁共振成像显示枕骨有一个2.5×6厘米的肿块，该肿块被次全切除。术后患者接受了放射治疗。目前，患者在随访20个月后未出现病情进展。
