A 32-year-old woman with no previous disease history was presented with worsening right-lower abdominal pain, which lasted for 4 days. On magnetic resonance imaging, a solid mass measuring 48 mm in longitudinal diameter connected with a tortuous structure that appeared to be a fallopian tube was identified in the right-lower abdomen. Because the right ovary was identified at a slightly distant location, isolated fallopian tube torsion with heterogeneous mass was suspected. The isolated fallopian tube torsion without ovarian involvement was laparoscopically confirmed. After detorsion, solid necrotized mass in the distal portion of the right fallopian tube near the fimbrial end became evident, followed by uneventful right salpingectomy with ovarian preservation. The pathological diagnosis was paraganglioma of the fallopian tube with positive cells for neural cell adhesion molecule, neuron-specific enolase, and S-100 protein in the viable peripheral foci of the massively necrotized hemorrhagic mass. Recurrence was not observed after 1.5 years.
一名既往无病史的32岁女性出现右下腹部疼痛加重，持续4天。磁共振成像显示，右下腹部有一个纵向直径为48毫米的实性肿块，与一个似乎是输卵管的迂曲结构相连。由于右侧卵巢位于稍远处，怀疑是孤立性输卵管扭转伴异质性肿块。经腹腔镜证实为无卵巢受累的孤立性输卵管扭转。扭转解除后，右侧输卵管伞端附近远端的实性坏死肿块变得明显，随后顺利进行了保留卵巢的右侧输卵管切除术。病理诊断为输卵管副神经节瘤，在大量坏死出血性肿块的存活周边灶中，神经细胞黏附分子、神经元特异性烯醇化酶和S-100蛋白的细胞呈阳性。1.5年后未观察到复发。
