Limb Amputation after Multiple Treatments of Tenosynovial Giant Cell Tumour: Series of 4 Dutch Cases

Figure 1

Case  1.

(a) Sagittal T1-weighted MR image, turbo-spin echo, after intravenous contrast injection in a 69-year-old female patient with recurrent, end stage TGCT on the right side. Extensive tumour growth around her total knee replacement (TKR), involving the entire knee joint, anterior and posterior, ranging from high up suprapatellar pouch to below tibia-fibular joint, including bone involvement

(b) Sagittal Short-TI Inversion Recovery metal clear MR image of the posterior part of the right knee, revealing extensive tumour growth, also growing outside the body. Characteristic TGCT blooming effect is seen attributed to scattered areas of low signal intensity, typical for iron deposition
