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. Nontraumatic joint swelling combined with recurrent, possibly hemorrhagic joint effusions must be considered signs of a synovial hemangioma. Although no preoperative diagnostic tool enables confirmation of the diagnosis, and MRI seems to be the diagnostic procedure of first choice, … Show more
“…The intra-articular lesion is lobulated with highsignal-intensity convoluted vessels without bone involvement. The presence of hemarthrosis may hinder the diagnosis and mimic a hemophiliac arthritis or a pigmented villonodular synovitis [ 30 ]. Early degenerative changes to the cartilage with early onset of osteoarthritis represent a complication of intra-articular hemangiomas.…”

“…Bei Beteiligung des Kniegelenks kommt es langfristig zu einer Quadrizepsatrophie und Zunahme der Länge des betroffenen Beins. Zusätzliche vaskuläre Veränderungen im Hautbereich über dem Gelenk können als Nävus, Hämangiom oder als Teleangiektasien auftreten (40%) [3,4,9,11,13,16,19].…”

“…Weitaus am häufigsten ist das Kniegelenk (97%) -v. a. im Bereich des Recessus suprapatellaris -betroffen, selten Ellbogen-, Sprung-, Finger-, Hand-und Temporomandibulargelenk sowie Sehnenscheiden [1, 3,5,6,8,13,17].…”
