case_images: fig1-2050313X231197009
case_images: Ultrasound examination showed a heterogeneously hypoechoic irregular nodular lesion in the subcutaneous plane without significantly increased vascularity (Figure 1).
case_images: (a) Axial T1 weighted MRI image showing low signal intensity poorly marginated irregular nodular lesion (white arrow) inseparable from left rectus abdominis and rectus sheath (green arrow). (b) Axial fat-saturated image showing the high signal intensity irregular lesion (white arrow) inseparable from left rectus abdominis and rectus sheath (green arrow). (c) T1 post-contrast axial image showing the irregular nodular lesion (white arrow) showing the heterogenous enhancement and abutting left rectus sheath (green arrow).

case_images: fig2-2050313X231197009
case_images: T1 low, T2 intermediate, and fat-saturated high signals in MR images (Figure 2(a) and (b)). The lesion shows heterogenous enhancement in post-contrast images and is inseparable from the rectus sheath and rectus abdominis (Figure 2(c)).
case_images: (a) Low power microscopic view showing a cluster of epithelial cells (green line) and aggregate of stromal cells (black line). (b) High-power microscopic view showing the fragment of endometrial stromal cells. (c) High-power microscopic view showing the cluster of endometrial epithelial cells.
