FIGURE 1 Imaging findings of the presented case. (A ) Thrombosis of the distal intermuscular vein of the right lower extremity. The lumen of the vein exhibits a moderately hypoechoic plaque, while color Doppler flow imaging (CDFI) detects a filling defect within the lumen, along with an absence of a blood flow signal. (B ) An abdominal CT scan illustrates a substantially enlarged uterus. (C ) Gynecologic ultrasound confirms the presence of adenomyosis.
