An extensive evaluation revealed an intercruciate ganglion c yst of the knee. Diagnostic arthroscopy of the right knee was performed, an d the cyst was aspirated and debrided. Magnetic resonance imaging of the kn ee 3 months and 1 year postoperatively showed a small remnant of the cyst a djacent to the posterior cruciate ligament.
