Fig. 1From: Gait analysis of a patient after femoral nerve and malignant soft tissue tumor resections: a case reportMagnetic resonance images. Magnetic resonance imaging shows a mass lesion in the left femur. The tumor occupying the sartorius muscle has a Hypointensity with few hyperintensities on T1-weighted image (WI) and b Hyperintensity on T2WI. c Fat-saturated T1WI shows some areas of hyperintensity in the mass, and d Gadolinium-enhanced fat-saturated T1WI shows enhancement in the mass lesion excluding the central regionBack to article page
