Lateral meniscal cyst presenting as Medial Compartment Knee Swelling: A case report and literature review

Abstract INTRODUCTION Meniscal cysts are relatively uncommon orthopaedic lesions usually arising from the meniscus. They present as clinically palpable masses and dull pain. PRESENTATION OF CASE We report on a 33-year-old male patient who presented clinically with a medial knee swelling that arose from a lateral meniscal cyst. DISCUSSION No similar cases were cited in the literature. The cyst was removed surgically with a good result obtained and no recurrence after 12 months. Typically, a clinically palpable mass corresponds to a meniscal cyst arising from the ipsilateral meniscus. CONCLUSION Magnetic resonance imaging is vital to exclude such anomalies prior to surgical intervention.
