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

INTRODUCTIONMeniscal cysts are relatively uncommon orthopaedic lesions usually arising from the meniscus. They present as clinically palpable masses and dull pain.PRESENTATION OF CASEWe report on a 33-year-old male patient who presented clinically with a medial knee swelling that arose from a lateral meniscal cyst.DISCUSSIONNo 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.CONCLUSIONMagnetic resonance imaging is vital to exclude such anomalies prior to surgical intervention.
