Isolated tubal torsion in the third trimester of pregnancy: A case report and review of the literature

Abstract

Isolated torsion of a fallopian tube in the third trimester of pregnancy is an uncommon event. Its common symptoms are lower abdominal pain, vomiting, and nausea. Because these symptoms are nonspecific, isolated torsion of a fallopian tube may be misdiagnosed, delaying treatment and the opportunity to preserve the tube. This is a case report of a primipara in her third trimester, who was misdiagnosed as having acute appendicitis and ovarian cyst torsion. The ultrasound-assisted examination was useful, but the specific diagnosis was made after laparotomy and histopathology. The patient was managed by simultaneous salpingectomy and cesarean section. This surgical intervention prevented adverse obstetric sequelae. We summarize our experience, provide our conclusions, and review 17 relevant studies from the literature to aid clinicians in understanding, diagnosing, and managing this condition in a timely fashion.
