Plain radiography can help in confirming the clinical diagnosis of a subungual glomus tumour, as erosive changes in the distal phalanx are present in 22% of cases. Such changes will be more easily identified on a lateral radiograph with the painful finger and its contralateral counterpart pointing toward each other: discrete scalloping of the distal phalanx will thus be made more evident.
X线平片有助于确诊甲下血管球瘤，因为22%的病例在远节指骨可见侵蚀性改变。在侧位X线片上，将患指与其对侧手指相对放置，更易识别这种改变：远节指骨的离散性扇贝样改变会因此更加明显。
