''Crushed glass'' appearance of particles observed in roentgenograms after hysterosalpingography as an indicator of pelvic abnormalities

Objective: To evaluate the diagnostic value of the crushed glass appearance of particles observed on roentgenogram after hysterosalpingography in patients with pelvic abnormalities. Design: Retrospective study of 32 patients whose roentgenogram had particles with a crushed glass appearance and 16 patients without crushed glass appearance, with laparoscopy conducted to determine the location and severity of the pelvic disease. Setting: Fujita Health University Hospital, Aichi, Japan. Patient(s): A total of 240 patients underwent hysterosalpingography to determine the cause of infertility. Main Outcome Measure(s): We compared the location of the pelvic endometriosis and/or inflammation that was observed on roentgenogram as the crushed glass appearance versus definitive findings at laparoscopy. Result(s): A total of 30 of the 32 cases (93.8%) with the crushed glass appearance were confirmed as having pelvic abnormalities, such as endometriosis (73.3%) and pelvic inflammation (26.7%). The rate of the concurrence of the location of the crushed glass appearance observed on the film and that of the lesions verified by laparoscopy was 66.7%. Histopathological examination showed that specimens taken from endometriosis or inflammatory lesions that comprised the crushed glass appearance were lacking in epithelium in proportion to the size of the particles. Conclusion(s): Identification of the crushed glass appearance of particles was a useful noninvasive method of detecting pelvic abnormalities, such as pelvic endometriosis and inflammation, in infertile women.
