INTRODUCTION
Most of pulmonary metastases present as well-defined solid and round nodules. Here we report a case of a pulmonary metastasis presenting as a ground glass opacity (GGO)-like lesion with a thin-walled cavity and lymph node metastasis of tongue cancer.
CASE PRESENTAION
A 22-year-old man was referred to our department for surgical diagnosis and treatment for a GGO-like pulmonary nodule with a thin-walled cavity in the right lower lobe. He had a history of surgical resection for tongue cancer. The size of the GGO-like lesion with a thin-walled cavity in the center gradually increased. A right lower lobectomy and hilar lymphadenectomy were performed. Postoperative pathology revealed the lesion as pulmonary metastasis and hilar lymph node metastasis of tongue cancer.
DISCUSSION
Our case report of pulmonary metastasis of tongue cancer is rare from the viewpoint of pulmonary GGO-like lesions with a following thin-walled cavity and hilar lymph node metastasis. The positron emission tomography/computed tomography (PET/CT) examination was useful to show right hilar lymph node metastasis.
CONCLUSION
It is important to make a differential diagnosis of from the pulmonary nodule in case of a GGO-like lesion with a thin-walled cavity.
引言
大多数肺转移瘤表现为边界清晰的实性圆形结节。在此，我们报告一例舌癌肺转移病例，其表现为磨玻璃样密度影（GGO）伴薄壁空洞及淋巴结转移。
病例介绍
一名22岁男性因右下叶出现一个伴有薄壁空洞的GGO样肺结节被转诊至我科进行手术诊断和治疗。他有舌癌手术切除史。中央伴有薄壁空洞的GGO样病变大小逐渐增大。遂行右下叶切除术及肺门淋巴结清扫术。术后病理显示该病变为舌癌肺转移及肺门淋巴结转移。
讨论
从伴有薄壁空洞及肺门淋巴结转移的肺部GGO样病变角度来看，我们的舌癌肺转移病例报告较为罕见。正电子发射断层扫描/计算机断层扫描（PET/CT）检查有助于显示右肺门淋巴结转移。
结论
对于伴有薄壁空洞的GGO样病变，与肺结节进行鉴别诊断很重要。
