Lipoma arborescente de la bursa bicipital

Intra-articular lipoma arborescens of the knee: A report of two cases with bilateral localization

“…In 46 cases of knee located lipoma arborescens found in the literature [ 6 , 7 ], the involvement was bilateral in only 8 cases, the average age is 46 years for men, 37 years for women [ 2 ]. The unilateral form affecting the knee is the most common, with a predilection for supra patellar recess [ 8 , 9 ]. The hip, wrist, elbow, ankle and bursae may also be affected [ 10 ].…”

“…The clinical examination finds symptoms of chronicity, such as progressive soft swelling, often very abundant joint effusion, pain, stiffness and episodes of joint blockage [ 1 ], which is exacerbated when the proliferation is interposed between articular surfaces [ 8 ]. Synovial fluid is usually acellular, sometimes moderately inflammatory or hemorrhagic [ [2] , [3] , [4] , [5] , [6] , [7] , [8] , [9] , [10] , [11] , [12] ].…”

Destrucción del tendón bicipital en el codo por bursitis bicipitorradial reumatoide

“…La etiopatogenia de las bursitis y nódulos reumatoides es desconocida. Los nódulos se desarrollan casi siempre en pacientes con artritis reumatoide y están presentes al menos en el 20-25% de los afectos por esta enfermedad 4,5 . Suelen situarse en las proximidades de las articulaciones y su tamaño oscila entre 1 y 5 cm de diámetro 4 .…”

“…El diagnóstico diferencial de las bursitis profundas y de los nódulos reumatoides debe hacerse con tumoraciones subcutáneas de partes blandas, especialmente con lesiones nodulares de una paniculitis lobulillar 4 y lipomas arborescentes de las bursas 5 .…”

Symptomatic bicipitoradial bursitis: a report of two cases and review of the literature

“…18 Magnetic resonance imaging studies are useful and accurate at diagnosing BRB, but it is difficult to distinguish BRB from interosseous bursitis when the bursa is very enlarged. 1,17 The differential diagnosis must include soft-tissue tumors (ie, lipoma), 5,15,21 infections, 9,16 tenosynovitis, ganglion cysts, 17 pigmented villonodular synovitis, 16 or malignant tumors. 2,9,12 The true diagnosis is not reached until a pathology study is carried out.…”
