Case Discussion
Though there was no clear history of trauma, a previous muscular injury may have given rise to these cysts. A possible alternative diagnosis is chronic iliotibial band friction syndrome with formation of a pseudobursa. Ganglion cysts arising from the quadriceps tendon have also been described, but there is no relation to this structure in this case.
