title: Efficacy of transabdominal sonoelastography in the diagnosis of caesarean section scar endometrioma: A pilot study.
abstract: Transabdominal sonoelastography (TASE) is a new imaging technique that maps the elastic properties of soft tissue. We evaluated 34, consecutive women with suspected scar endometrioma using standard B-mode ultrasound and elastography. Twenty-three women (23/34) underwent surgical excision and had the diagnosis confirmed by histopathology. All endometriomas (23 patients) in B-mode imaging appeared as hypoechoic masses along the line of a previous caesarean section incision and the outer borders were difficult to define precisely. By TASE, the endometrioma presented a typical blue-green-red appearance and the outer borders were clearly defined. (red and green area corresponds with the central hypoechoic soft areas). Strain ratios varied from 0.02 to 0.75. Real-time TASE is a simple, useful technique in confirming a clinical diagnosis of endometrioma in a caesarean section scar. Compared with B-mode ultrasound, it provides additional, preoperative information about the extent of the lesion that may be helpful to the surgeon.
