Abstract

A rare case of a posttraumatic extensive ganglion cyst of the anterolateral thigh with connection to the knee joint is presented. A 54-year-old man presented a palpable mass in the anterolateral region of his right thigh with a 15 months existing sense of fullness and tightness. He had an accident with his bicycle 21 months ago. Magnetic resonance imaging (MRI) was performed showing a cyst inside the quadriceps femoris muscle between vastus lateralis and intermedius with connection to recessus suprapatellaris and knee joint. In addition MRI detected a traumatic lesion in the quadriceps femoris tendon in the near of the knee joint. The ganglion cyst was 18 cm long and was excised completely. Intraoperatively, the knee joint connection was confirmed and excised as well. The ganglion cyst was filled with a gelatinous and viscous fluid.

Keywords: ganglion cyst; knee joint.; post-traumatic; quadriceps femoris tendon.

Preoperative magnetic resonance imaging; T2-weighted coronal plane (left picture) of the right thigh and knee show an extensive T2-hyperintense lesion inside the right quadriceps femoris muscle. Axial magnetic resonance imaging of the right thigh (right picture) shows the ganglion cyst with a septum membrane inside the cyst.

Figure 2
Preoperative magnetic resonance imaging of the right (R) and left (L) thigh (axial plane) detects traumatic lesion in the right quadriceps femoris tendon (red arrow) adjacent to the knee joint. Please note the difference to the normal tendon on the left side (blue dotted arrow), which appears as a hypointense curved structure similar to an eyebrow.

Intraoperative picture showing the ganglion cyst inside the right thigh with a length of 18 cm. The cyst was inside the quadriceps femoris muscle between vastus lateralis and intermedius and was excised completely under general anaesthesia. The ganglion cyst was filled with a gelatinous and viscous fluid. The fluid seemed to be under moderate pressure.
