US AND COLOR DOPPLER FINDINGS OF ENDOMETRIOMA OF THE ABDOMINAL WALL NEAR CESAREAN SECTION SCAR. A SERIES OF 17 PATIENTS

This paper describes ultrasonography and color Doppler findings in 17 women with painful abdominal wall nodules near a prior cesarean section scar, all of whom had at least one cesarean section. Using high-frequency linear transducers and Doppler settings aimed at low-velocity flow, the authors report that ultrasound commonly showed hypoechoic inhomogeneous lesions with internal hyperechoic echoes, irregular spiculated infiltrative margins, and a variable hyperechoic ring. Color Doppler demonstrated a single vascular pedicle at the mass periphery in 12 cases, with abundant intralesional vascularization in 4 larger lesions, while power Doppler did not add significant information; a stated limitation is the small, single-series design without explicit diagnostic accuracy metrics. This paper is centrally about endometriosis — it specifically characterizes abdominal wall endometrioma arising near cesarean section scars using US and Doppler features.
