A retrospective study was undertaken to evaluate the radiologic appearance of salpingitis isthmica nodosa (SIN) in the fallopian tubes of 150 consecutive patients having hysterosalpingograms performed almost exclusively for primary and secondary infertility. SIN was observed in 13 of these 150 patients. The characteristic radiologic features of this condition are minute loculations of contrast medium adjacent to the tubal lumen which range in size up to 2 mm in diameter and are clustered together over a tubal length of 1 to 2 cm. Although the most frequent site of occurrence is in the proximal isthmic portion of the tube, there is occasional involvement of the distal isthmus and even the interstitial portion of the adjacent uterine cornu. Associated tubal abnormalities in this condition such as hydrosalpinx and tubal occlusion help explain the increased incidence of tubal pregnancy and infertility in patients with SIN.
进行了一项回顾性研究，以评估150例连续接受子宫输卵管造影术的患者输卵管中结节性峡部输卵管炎（SIN）的放射学表现，这些患者几乎均因原发性和继发性不孕症而进行该检查。在这150例患者中，有13例观察到SIN。该病的特征性放射学表现为紧邻输卵管腔的造影剂微小分叶，直径可达2mm，在1至2cm的输卵管长度上聚集在一起。虽然最常见的发生部位是输卵管近端峡部，但远端峡部甚至相邻子宫角的间质部偶尔也会受累。这种情况下相关的输卵管异常，如输卵管积水和输卵管阻塞，有助于解释SIN患者输卵管妊娠和不孕发生率增加的原因。
