The calcaneus is a rare location for the development of primary bone tumours. The purpose of the study is to review the imaging findings in a cohort of patients presenting with tumours and tumour-like lesions of the calcaneus and to develop a more structured approach to the diagnosis of calcaneal lesions.
A retrospective study with a collection of 167 cases of calcaneal tumours and tumour-like lesions from our tertiary orthopaedic oncology institution over a period of 13 years. Cases were reviewed by two consultant musculoskeletal radiologists and the location of the lesion within the calcaneus and demographics of the patient were noted for each case. A diagnostic algorithm, which is based on patient age and tumour location, was then extrapolated.
Out of the 167 cases, we identified 24 different calcaneal pathologies which included both tumours and tumour-like lesions. The most common being simple bone cysts (18.3% of cases) and intra-osseous lipoma (15% of cases) sited in the diaphyseal equivalent of the calcaneus. A diagnostic algorithm was formulated, which describes the most common location of the different pathologies including both benign and malignant pathologies, subdivided by age.
Our algorithm should help the radiologist narrow down the differential diagnosis when evaluating calcaneal lesions.
This article provides a radiological approach to calcaneal lesions.
跟骨是原发性骨肿瘤少见的发病部位。本研究的目的是回顾一组跟骨肿瘤和肿瘤样病变患者的影像学表现，并制定一种更具结构性的方法来诊断跟骨病变。
这是一项回顾性研究，收集了 13 年来我们的三级骨科肿瘤专科医院的 167 例跟骨肿瘤和肿瘤样病变病例。由两名顾问肌肉骨骼放射科医生对这些病例进行了回顾，并记录了每个病例的病变在跟骨内的位置和患者的人口统计学资料。然后，根据患者年龄和肿瘤位置推导出了一种诊断算法。
在 167 例病例中，我们确定了 24 种不同的跟骨病理，包括肿瘤和肿瘤样病变。最常见的是单纯性骨囊肿（18.3%的病例）和骨内脂肪瘤（15%的病例），位于跟骨骨干的等效部位。我们制定了一个诊断算法，描述了不同病理的最常见位置，包括良性和恶性病理，并按年龄进行了细分。
当评估跟骨病变时，我们的算法应该有助于放射科医生缩小鉴别诊断的范围。
本文提供了一种跟骨病变的放射学方法。
