头部和颈部的软组织钙化是相对常见的,并且是多种良性和恶性病变的结果。鉴于广泛的潜在病因,它们可以提出诊断挑战。尿毒症性肿瘤钙质沉着症(UTC)是由转移性软组织钙化引起的终末期肾病(ESRD)的罕见并发症。常见部位包括肩关节周围软组织,肘部,和手(潘和陈,2016)。UTC还可以影响颈椎和模仿骨肉瘤(Zhou等人。,2018)。我们介绍了一个71岁的高血压女性,左颈动脉狭窄,二尖瓣脱垂,和继发于II型糖尿病(DMII)腹膜透析的ESRD,异质,双侧颈部钙化肿块。鉴于她的临床病史,实验室结果,和影像学发现,她被诊断为UTC。除了这个案例,我们提供肿瘤钙质沉着症(TC)的概述和头颈部钙化病变的鉴别诊断.
Soft-tissue calcifications in the head and neck are relatively common and are the result of a wide variety of benign and malignant pathologies. They can present a diagnostic challenge given the broad range of underlying etiologies. Uremic tumoral calcinosis (UTC) is a rare complication of end-stage renal disease (ESRD) resulting from metastatic soft tissue calcification. Common sites include periarticular soft tissues of the shoulders, elbows, and hands (Pan and Chen, 2016). UTC can also affect the cervical spine and mimic osteosarcomas (Zhou et al., 2018). We present the case of a 71-year-old female with hypertension, left carotid artery stenosis, mitral valve prolapse, and ESRD secondary to diabetes mellitus type II (DMII) on peritoneal dialysis who was found to have large, heterogeneous, bilateral calcified neck masses. Given her clinical history, laboratory results, and imaging findings, she was diagnosed with UTC. In addition to this case, we provide an overview of tumoral calcinosis (TC) and a differential diagnosis for calcified lesions of the head and neck.
