Complementary Effects of Surgery and Pexidartinib in the Management of Patients with Complex Diffuse-Tenosynovial Giant Cell Tumor

Figure 13

Effusion in the knee of a 55-year-old male with D-TGCT. No tumor recurrence is observed following rupture of anterior cruciate ligament. (a) This axial view with contrast of the distal femur shows a suprapatellar pouch effusion with hyperintense capsular enhancement (plus). No tumor is visible. (b) The axial view at the level of the menisci has areas of hypointensity interpreted by the radiologist as scar rather than tenosynovial giant cell tumor along the posterior cruciate ligament insertion (star). (c) This sagittal view shows a dramatic reduction of the popliteal cyst with small residual nodules of debris in the cyst (arrow).
