Isolated tumours affecting the coccyx are infrequent, with only a handful of documented cases in the literature. Herein, we highlight the most extensive consecutive case series involving various isolated coccyx tumours with varied clinical presentations and imaging features.
A retrospective search of our tertiary Orthopaedic oncology institute's oncology and Radiology database [Radiology Information System, Picture Archiving and Communication System, and Computerised Radiology Information System] for the keyword "Coccyx" and "Tumour" was performed over 15 years (between December 2007 and August 2022). Data collected was correlated with local histopathology and laboratory records. Patient demographics, clinical characteristics, and complementary imaging findings were recorded for analysis.
One hundred and three lesions originating in the coccyx with a mean age of 62 years (range 25-90 years) were identified. There was a male preponderance with 59 male and 44 female patients (1.3:1.0). The most typical tumour noted was chordoma. Other lesions included a dermoid cyst, a myxopapillary ependymoma, a notochordal remnant, an osteochondroma, an Ewing sarcoma, and a teratoma.
Our analysis suggests that most of the tumours involving coccyx are chordomas with a few rarely encountered benign and malignant tumours. Radiological imaging plays a vital role in characterising isolated tumours affecting the coccyx and guiding appropriate patient management.
This is the largest reported series of coccygeal tumours. Chordoma is the commonest coccygeal tumour. Patients with unexplained coccydynia should undergo detailed investigations, preferably with cross-sectional imaging.
孤立性尾骨肿瘤较为罕见，文献中仅有少数病例报道。在此，我们重点介绍了涉及各种临床表现和影像学特征的孤立性尾骨肿瘤的最广泛连续病例系列。
对我们的三级骨科肿瘤研究所的肿瘤学和放射学数据库[放射学信息系统、影像归档和通信系统以及计算机化放射学信息系统]进行了 15 年（2007 年 12 月至 2022 年 8 月）的回顾性搜索，使用了关键词“尾骨”和“肿瘤”。收集的数据与局部组织病理学和实验室记录相关联。记录患者的人口统计学、临床特征和补充影像学发现进行分析。
共发现 103 个起源于尾骨的病变，平均年龄为 62 岁（范围 25-90 岁）。男性居多，有 59 名男性和 44 名女性患者（1.3:1.0）。最常见的肿瘤是脊索瘤。其他病变包括皮样囊肿、黏液乳头状室管膜瘤、脊索残迹、骨软骨瘤、尤文肉瘤和畸胎瘤。
我们的分析表明，大多数涉及尾骨的肿瘤是脊索瘤，少数是罕见的良性和恶性肿瘤。放射影像学在特征化孤立性尾骨肿瘤和指导适当的患者管理方面发挥着重要作用。
这是报道的最大系列的尾骨肿瘤。脊索瘤是最常见的尾骨肿瘤。不明原因尾痛的患者应进行详细检查，最好进行横断面成像。
