Ultrasound examination showed a heterogeneously hypoechoic irregular nodular lesion in the subcutaneous plane without significantly increased vascularity (Figure 1).
(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).

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)).
(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.
