Atypical Presentation of Gouty Tophus as Posterior Cruciate Ligament Cyst: A Case Report.

Introduction: Gouty tophi generally develop around 10 years after the first attack of gout in untreated patients and are commonly found around feet, hands, and elbows. However, tophi can also occur as first sign of disorder. Tophaceous gout presenting in young at the posterior cruciate ligament (PCL) is extremely rare and difficult to diagnose because of its atypical presentation and no hallmark features in magnetic resonance imaging (MRI).
