Synovial Hemangioma

Hemangioma of Synovium


  • It presents frequently in the knee with pain, tenderness, intermittent swelling and recurrent hemarthrosis. MRI can be helpful in diagnosis of synovial hemangioma.[ncbi.nlm.nih.gov]

Constitutional Symptom
  • Case Report This healthy 2-year old girl presented with painless right elbow swelling for 3 months with no history of fever, weight loss, or other constitutional symptoms.[file.scirp.org]

  • Cytologically, synovial sarcoma shows highly cellular aspirate with clustered or cohesive malignant cells.[jmgims.co.in]
  • The diagnosis is best made by eliciting a characteristic history and physical examination, finding grossly bloody fluid on joint aspiration, and pursuing with arthrography or arthroscopy and then arthrotomy.[semanticscholar.org]
  • Repeated aspiration yielded only blood. Arthrotomy with synovectomy was done. Histopathology of the resected specimen showed a synovial hemangioma. No References No Citations No Supplementary Data No Article Media No Metrics[ingentaconnect.com]

  • […] of synovial hemangioma include pigmented villonodular synovitis (PVNS), non-specific synovitis and lipoma arborescens. [5] From a pathologic standpoint, the differentials of this entity include PVNS, non-specific synovitis, organizing hemorrhage and angiomatosis[ijpmonline.org]
  • Lipomatosis, liposarcoma, angiomatosis, angiosarcoma has been described earlier as differential diagnosis of intramuscular hemangima. However, synovial sarcoma has rarely been described in differential diagnosis of intramuscular hemangioma earlier.[jmgims.co.in]

Skin Lesion
  • Capillary refill was normal and there were no skin lesions.[ispub.com]
Knee Pain
  • Synovial hemangioma should be considered in the differential diagnosis of knee pain, particularly after more common diagnoses have been ruled out.[ncbi.nlm.nih.gov]
  • In cases of nonspecific symptoms and longstanding knee pain the diagnosis of a synovial hemangioma should also be considered in order to avoid diagnostic delay.[dieorthopaedin.at]
Joint Swelling
  • It may be a cause of pain and recurrent joint swelling in children and young adults. This report presents a 29-year-old patient with a synovial hemangioma in the left knee joint.[ncbi.nlm.nih.gov]
Knee Effusion
  • Linson, Ira Posner Published in JAMA 1979 DOI: 10.1001/jama.1979.03300200044024 SYNOVIAL hemangioma is an unusual cause of knee effusions, but must be considered in the individual who has recurrent nontraumatic knee effusions.[semanticscholar.org]

Synovial Hemangioma

  • Abstract We report our clinical experiences in the diagnosis and treatment of four patients with synovial hemangiomata. Synovial hemangiomata are rare causes of recurrent, nonspecific joint complaints and occur most often at the knee joint.[ncbi.nlm.nih.gov]


  • What is the Prognosis of Synovial Hemangioma? (Outcomes/Resolutions) The prognosis of Synovial Hemangiomas is generally very good, when the lesions are small.[dovemed.com]
  • Following total excision, prognosis is usually excellent and recurrence is rare. No recurrences were detected during a follow-up period of 16 months.[agris.fao.org]
  • Long-standing synovial hemangiomas which are localized with spared articular cartilage have a good prognosis with arthroscopic synovectomy.[jocr.co.in]
  • The most significant histologic differential, in terms of prognosis, is PVNS, a lesion which has a significant risk of recurrence.[ijpmonline.org]

  • Epidemiology Intramuscular hemangiomas Most deep soft tissue hemangiomas probably are asymptomatic and small and go completely unnoticed; therefore, the exact incidence and prevalence are impossible to determine with any degree of certainty.[emedicine.medscape.com]

  • Irrespective of the primary aetiology, electrophysiological studies suggest that the underlying pathophysiology relates to compression of the vasa nervosum of the nerve [ 6 Sunderland S.[benthamopen.com]
  • Pathophysiology Hemangiomas are benign lesions with increased numbers of blood vessels.[emedicine.medscape.com]


  • Early diagnosis is important to prevent prolonged suffering from chronic joint swelling with probable joint damages, unnecessary treatment procedures and as well school and sports absenteeism.[ncbi.nlm.nih.gov]
  • Orthopedicians must exercise a high index of suspicion, as prompt diagnosis and treatment can prevent progressive secondary degeneration of the joint.[jocr.co.in]
  • They are benign tumors with risk of local recurrence between 18% and 50%. [15], [16] Preoperative diagnosis is important; however, to properly evaluate feeding arterial blood supply and prevent potential operative morbidity. [17] Treatment is aimed at[jmgims.co.in]
