case_images: (a) Magnetic resonance imaging of left knee: T1-weighted images sagittal image, shows that the mass iso intense located in contact with the medial femoral condyle with bony scalloping, (b) T2-weighted images (T2 WI) coronal image, (c) T2 WI sagittal image, the mass appears heterogeneously hyperintense causing cortical scalloping of the medial femoral condyle.

case_images: T1-weighted and T1-weighted fat saturated images were also included in the study. The mass was iso intense on T1W1 [Figure 1] and the signal intensity was not suppressed upon T2FS [Figure 2].
case_images: (a) Magnetic resonance imaging (MRI) T2-weighted fat-saturated sagittal image, (b) MRI T2-weighted fat-saturated coronal image, (c) MRI T2-weighted fat-saturated axial image shows high-intensity lesion attached to the medial femoral condyle of left knee, no signs of bone marrow edema.

case_images: (a) Magnetic resonance (MR) post-contrast, T1-weighted images (T1WI) Sagittal image, (b) MR post-contrast, T1WI fat-saturated axial image, shows the mass deep to the medial retinaculum with heterogeneous intense post-contrast enhancement.

case_images: Post-gadolinium (Gd) administration, the mass demonstrated intense yet heterogeneous enhancement [Figure 3].
