Synovial Hemangioma in the Knee: MRI Findings (original) (raw)

Synovial hemangioma of the knee: MRI findings in two cases

Skeletal Radiology, 1995

The findings in two patients with histologically proven synovial hemangioma of the knee are described. Both cases emphasize the typical appearance of this unusual tumor on magnetic resonance imaging. Additional radiologic findings, such as adjacent osseous involvement, are discussed.

Synovial Hemangioma of the Knee Joint: Magnetic Resonance Imaging Findings

Polish Journal of Radiology, 2015

Background: Synovial hemangioma is benign tumor of the joints and is seen relatively rare. The most affected joint is knee but should also be seen in other joints. The disease is usually symptomatic. They are classified as juxta-articular haemangioma, intra-articular haemangioma or an intermediate type of hemangioma with intra-and extraarticular components.

Synovial hemangioma and osteoarthritis of the knee: a case report

Acta orthopaedica et traumatologica turcica, 2014

This report presents an adult patient suffering from knee osteoarthritis and gross hypertrophy of the synovium, preoperatively interpreted as a nonspecific synovial reaction. The patient underwent a total knee replacement and a complete synovectomy was performed. Histological examination disclosed a synovial hemangioma, which is a rare intra-articular, benign tumor of youth.

Synovial hemangioma: a pictorial essay of two cases

International Journal of Research in Medical Sciences, 2017

Synovial hemangiomas are uncommon benign tumours of vascular origin arising in relation to the synovium of joints or bursae. Usually, a long-standing history of pain and joint swelling is present affecting children and adolescents especially in the knee or elbow joint. We present two cases of knee swelling diagnosed as synovial hemangioma.

Intra-articular Synovial Hemangioma: A Rare Cause of Knee Pain and Swelling

Journal of Clinical Imaging Science, 2021

Synovial hemangioma is a rare intra articular lesion and it has several more common differentials. Therefore, our main objective is to consider the possibility of hemangioma in any intra-articular mass to prevent diagnostic delay of unnoticed or untreated hemangioma occurring within the knee joint. Ultrasound can be useful method in assessing the lesions. Surgical excision is the definitive treatment for such lesions.

Synovial hemangiohamartomas of the knee joint

Archives of Orthopaedic and Trauma Surgery, 2007

Hemangioma or vascular malformation of the synovium is rare and presents a difficult problem in diagnosis and treatment. A long history of joint pain and recurrent non-traumatic hemarthrosis usually draws attention to the hemangioma of the knee joint. The lesion can be seen in two different formations; the synovial hemangioma or the arteriovenous malformation named as hemangiohamartomas, both of which involve the synovium and cause non-traumatic episodes of hemarthrosis. MRI scanning together with arthroscopy is a diagnostic tool to demonstrate the extent and the nature of the lesion. We treated the three patients at different ages. All patients underwent standard radiographic examination, CT scans, MRI and diagnostic arthroscopy. After frozen section taken via arthroscopically, the lesions were excised by arthrotomy. The mean follow-up was 38 months (31-45) and all patients are asymptomatic postoperatively. Three additional cases and a review of the literature are presented because of the rarity of the lesion.
