Tumor de la Vaina tendinosa
Femenina 46 años edad con antecedente de cirugía en cara volar de muñeca izquierda. Se le aprecia nodulo duro en encima de la cicatriz quirúrgica. Refiere dolor que se extiende a los dedos de la mano y calambres.El examen sonografico muestra nodulo solido,hipo-ecogenico, en relacion a tendón flexor de 3er dedo- Los limites son ligeramente irregulares. El nodulo mide aprox: 8,3 X 7,4 mm.El eco-Doppler muestra flujo vascular en la parte mas profunda del nodulo y la Elastografia muestra patrón de Color con score 2 de Ueno-lo cual sugiere benignidad-.La parte distal del nodulo hipoecogenico se continua con presencia de masa ecogena-fibrotica.
En el área proximal de la articulación metacarpo-falángica del 2do dedo ,rodeando el tendón flexor, se aprecia área an-ecogena por presencia de liquido en la zona.
Se concluye con los diagnósticos de nódulo sólido del tendón flexor del 3er dedo mano izquierda,por tumor de la vaina tendinosa,posiblemente un tumor de células gigantes de la vaina del tendón, y de tenosinovitis tendón flexor del 2do dedo.
El tumor de células gigantes de la vaina tendinosa es benigno, de etiologia desconocida, con tendencia a las recidivas.La forma localizada de esta afección es mas frecuente en mujeres sobre todo entre los 30-50 años,se desarrolla predominantemente en los tendones flexores de la mano, sobre todo en la cara volar de los tres primeros dedos, tal como es el caso que presentamos.
Female 46 years old with a history of surgery on the face of the left wrist. You can see a hard nodule on top of the surgical scar. It refers to pain that extends to the fingers of the hand and cramps. The sonographic examination shows a solid, hypo-echogenic nodule, in relation to the flexor tendon of the third finger. The limits are slightly irregular. The nodule measures approx: 8.3 X 7.4 mm. The Doppler echo shows the vascular flow in the deepest part of the nodule and the Elastography shows a Color pattern with an Ueno score of 2, which suggests benignity. The distal part of the hypoechoic nodule is continued with the presence of fibrogenic echogenic mass.
In the proximal area of the metacarpophalangeal joint of the 2nd finger, surrounding the flexor tendon, the an-echogenic area is seen due to the presence of fluid in the area.
We conclude with the diagnosis of a solid nodule of the flexor tendon of the 3rd left-hand finger, by tendon sheath tumor, possibly a giant cell tumor of the tendon sheath, and flexor tendon tenosynovitis of the 2nd finger.
The giant cell tumor of the tendon sheath is benign, of unknown etiology, with a tendency to relapse. The localized form of this condition is more frequent in women especially between 30 and 50 years, it develops predominantly in the flexor tendons of the hand, especially in the flying face of the first three fingers, as is the case we present.
