To present the magnetic resonance imaging (MRI) findings for tear of the distal biceps tendon presenting as a soft-tissue mass in the antecubital fossa.
The authors identified four patients who had been referred for MRI of an antecubital soft-tissue mass and in whom a tear of the distal biceps tendon was found.
All four patients had typical MRI findings for a tear of the distal biceps tendon. In three, a tear at the insertion of the tendon onto the radial tuberosity was associated with small fluid collections at the site of the tear. In one patient there was thinning of the tendon and fluid within the tendon sheath. The diagnosis was confirmed by clinical correlation and follow-up of at least 1 year (in two patients) or by surgical exploration (in two).
With knowledge of the MRI appearance of distal biceps tendon tear, it should be possible to correctly diagnose the problem, even when the clinical presentation does not suggest the diagnosis.
呈现远端肱二头肌腱撕裂在肘前窝表现为软组织肿块的磁共振成像（MRI）结果。
作者确定了四名因肘前软组织肿块接受MRI检查且发现远端肱二头肌腱撕裂的患者。
所有四名患者均有远端肱二头肌腱撕裂的典型MRI表现。其中三名患者，肌腱在桡骨粗隆附着处的撕裂与撕裂部位的少量积液有关。一名患者出现肌腱变薄及腱鞘内积液。通过临床关联及至少1年的随访（两名患者）或手术探查（两名患者）确诊。
了解远端肱二头肌腱撕裂的MRI表现后，即使临床表现未提示诊断，也应能够正确诊断该问题。
