“…The lesions that arise as a result of the two conditions, especially in the fingers, are similar in size, location, and gross morphological features. Moreover, magnetic resonance imaging (MRI) manifestations are similar between FTS and GCTTS in previous studies (3)(4)(5)(6)(7). These tumors typically have a signal intensity (SI) that is lower than or equal to that of skeletal muscle on T1-weighted (T1W) and T2-weighted (T2W) imaging (8).…”

Background The differential diagnosis of fibroma of tendon sheath (FTS) and giant cell tumor of tendon sheath (GCTTS) on the basis of clinical and radiographic characteristics remains difficult. Purpose To evaluate the quantitative measurement of signal intensity (SI) obtained by magnetic resonance imaging (MRI) for the differential diagnosis of FTS and GCTTS in just the finger. Material and Methods We retrospectively identified patients with FTS (n = 6) and GCTTS (n = 22) of the finger who were treated at our hospitals between April 2011 and August 2019. Two researchers independently reviewed the MRIs and measured the regions of interest (ROIs) in the tumor and flexor tendon from the same image. The SI ratio obtained for the tumor and tendon ROIs was measured and compared using receiver-operating characteristic curve analyses. Sensitivity and specificity analyses were performed. Results The SI ratios (mean ± SD) of FTS and GCTTS were 1.83 ± 0.64 and 6.34 ± 3.16 for researcher 1 and 1.82 ± 0.60 and 6.10 ± 3.22 for researcher 2, respectively. The areas under the curve were 0.970 and 0.970 for researchers 1 and 2, respectively. The cut-off values of the SI ratio as determined by researchers 1 and 2 for differentiating FTS from GCTTS were 3.00 and 3.00, respectively (sensitivity = 95.5%, specificity = 100%). Conclusions The SI ratio is useful for differentiating FTS from GCTTS independent of a combination of tumor signal and shape.

Lo más frecuente es que se trate de un proceso casi exclusi-vamente intraarticular y las lesiones extraarticulares son generalmente extensiones del proceso 1,2,3,4,5,6,7,8 .…”

Giant cell tumor of the tendon seath of the tendinous insertion in pes anserinus

Abstract: A 56-year-old woman with a palpable lump in the medial surface of her left knee was referred for diagnostic workup with magnetic resonance imaging. The lesion was pathogically confirmed to be a giant cell tumor of the tendon seath. The MR features of the lesion are presented.
