Characteristics of primary giant cell tumor in soft tissue on magnetic resonance imaging: A case report

Figure 1 A 36-year-old woman was admitted to our hospital with swelling, skin redness and pain in the upper limb that persisted for 6 mo without a prior history of trauma. A: Plain computed tomography (CT) imaging shows an irregular hypodense mass in the superficial deltoid muscle extending to the intermuscular space (white arrow) with axillary lymphadenopathy (orange arrow); B: Contrast CT (venous phase) reveals a slightly persistent inhomogeneous enhancement of the mass with a blurred margin (white arrow).
