Abstract
Spontaneous rupture of the tibialis anterior tendon is rare among ordinary people. The tendon rupture usually occurs in patients iatrogenically after local steroid injection to the tendon or with pre-existing systemic disease such as diabetes mellitus, gout, and rheumatic disease. However, no case of complete rupture of the tibialis anterior tendon due to an intratendinous ganglion cyst has been reported. We report on a case of a 39-year-old female with spontaneous rupture of the tibialis anterior tendon due to intratendinous ganglion cyst and her clinical results.

![]() | Figure 1Photograph showing mild erythematous skin color change and swelling just anterior of the tibialis anterior tendon. |
![]() | Figure 2Magnetic resonance imaging showing the cystic lesion located along the tibialis anterior tendon. Low signaled in T1-weighted image (A, B) and high signaled in T2-weighted image. (C, D) Continuity of tibialis anterior tendon near the cystic lesion was not seen, suggesting complete rupture. |
