Benign notochordal cell tumor (BNCT) is a benign lesion derived from notochordal cells. Although it is relatively common in intraosseous lesion, pulmonary BNCT is extremely rare. We present a case of 54-year-old male with multiple pulmonary nodules, in which were considered to be metastatic chordomas initially. For 20 months follow-up without any therapy, most of the nodules had no remarkable change but some nodules showed cystic change. We consulted with pathologists specializing in chordoma and the final diagnosis of the nodules was considered as BNCT rather than chordoma. We herein report the case of multiple pulmonary BNCTs with cystic change, comparing with previous reports.
良性脊索细胞瘤（BNCT）是一种起源于脊索细胞的良性病变。尽管它在骨内病变中相对常见，但肺部BNCT极为罕见。我们报告一例54岁男性，有多个肺结节，最初被认为是转移性脊索瘤。在未经任何治疗的20个月随访中，大多数结节无明显变化，但一些结节出现了囊性改变。我们咨询了专门研究脊索瘤的病理学家，最终结节的诊断被认为是BNCT而非脊索瘤。我们在此报告伴有囊性改变的多发性肺部BNCT病例，并与既往报告进行比较。
