An aberrant presentation of medial collateral ligament ganglion cyst: The value of magnetic resonance imaging in diagnosis

Soft-tissue cystic swellings at the knee joint level are commonly diagnosed as meniscal cysts. We present an interesting case diagnosed as a recurrent meniscal cyst, having had previous three surgical excisions but turned out to be a medial collateral ligament ganglion cyst, confirmed on a magnetic resonance imaging (MRI) scan. This was totally excised and went on to heal with no signs of recurrence after 6 months of follow-up. We have learnt that all recurrent cystic swellings at knee joint level should be approached with caution and we recommend MRI as the gold standard for further evaluation to aid in appropriate surgical management.
