A Rare Cause of Recurrent Pain in Athletes: Synovial Hemangioma

Abstract

Background: Synovial hemangioma is a rare neoplastic lesion, which can result in recurrent hemarthrosis and pain. It can affect any joint, tendon, or bursa, withal those around the knee. The intra-articular lesion is more prevalent and is more frequently diagnosed in female children or young adults. Indications: Surgery is indicated when patients present with recurrent painful hemarthrosis that affect daily living and functionality. Technique Description: Diagnostic knee arthroscopy, initially without tourniquet inflation, was performed to detect and study the extent of the lesion. Afterwards, the tourniquet was inflated to proceed with the surgical excision. Medial parapatellar approach was performed, and limits of the hemangioma were identified. Wide resection was performed taking care to not damage the medial meniscus and medial condyle cartilage. Neoplastic lesion was sent to pathology analysis. The tourniquet was deflated and hemostasis checked because these lesions can present extensive bleeding. Results: Localized, well-circumscribed, and encapsulated lesions have been reported to usually present low recurrence rate when completely excised. Discussion/Conclusion: It is a rare disease, and around 200 cases have been reported; therefore, conclusions about treatment and outcomes rely mostly on case series and case reports. Early diagnosis and treatment are paramount to prevent degenerative changes secondary to recurrent hemarthrosis.
