Tumor de células gigantes de la vaina tendinosa de la mano. Estudio de la epidemiología, eficacia de las pruebas de imagen en su diagnóstico y análisis de la recidiva

Abstract

ObjectivesTo determine the diagnostic accuracy of different imaging tests used in our Center. Assess whether the distribution of the different variables that define the tumor is the same as in the tumors with and without recurrence. Methods54 cases of giant cell tumor of the tendon sheath of hand were evaluated. In all radiography it was performed, ultrasound in 19 cases and 7 MRI. The data analyzed were: sex, age, history of trauma, finger affection, location, results of imaging tests, pathologic features of the tumor (size and number of nodules), and presence or absence of recurrence. ResultsThe female/male ratio was 1.7, right hand and the second finger were the most common sites. None was diagnostic radiography, ultrasound had a positive predictive value of 36.8% and 71.4% MRI. 6 cases of recurrence, with no statistically significant relationship between recurrence and the size, number of nodules or osteoarthritis. ConclusionMRI has superior diagnostic capability of ultrasound and ultrasound is superior to plain radiography in the diagnosis of GCT tendon sheath in hand.The non-significant association with any recurrence of the rated factors does not mean that does not exist.
