The present study aims to present a case of a subungual glomus tumour with literature to the findings on magnetic resonance (MR) imaging. A 51-year-old man consulted his physician because of a pain in the nail bed of his thumb, which he had had for 2 years. A plain radiography and MR examination was performed. Physical examination showed a blue-brown focus beneath the nail and there was deformation. A plain radiography demonstrated no abnormality. T1-weighted spin-echo images showed a well-marginated, oval, slightly hyperintense lesion (4 mm diameter) located in the subungual region. On turbo spin-echo T2-weighted images the lesion was hyperintense with a hypointense rim. T1-weighted spin-echo images after intravenous administration of contrast medium showed strong enhancement. The lesion was completely excised at surgery and the diagnosis of a glomus tumour was established histologically. In conclusion, MR imaging offers excellent diagnostic information about a clinically suspected glomus tumour.
本研究旨在报告一例甲下血管球瘤病例，并结合文献阐述其磁共振（MR）成像表现。一名51岁男性因拇指甲床疼痛2年就诊。进行了X线平片和MR检查。体格检查发现指甲下有一个蓝褐色病灶，并有变形。X线平片未显示异常。T1加权自旋回波图像显示甲下区域有一个边界清晰的椭圆形稍高信号病灶（直径4mm）。在快速自旋回波T2加权图像上，病灶呈高信号，边缘为低信号。静脉注射造影剂后的T1加权自旋回波图像显示病灶强化明显。手术中完整切除病灶，组织学诊断为血管球瘤。总之，MR成像可为临床疑似的血管球瘤提供极佳的诊断信息。
