Adnexal torsion in a first-trimester pregnant patient without any predisposing factor: A case report

SummArY Adnexal torsion is an uncommon case during pregnancy. Torsion usually occurs in ovaries with previously diagnosed cysts or tumors. It is rare for a previously normal ovary to undergo torsion in advanced gestation. Here, we report a case of adnexal torsion during the 9th week of pregnancy without any predisposing factors. The patient was admitted to emergency department with mild lower abdominal pain and nausea. With the worsening of clinical and ultrasonographic signs, a right salpingo-ovariectomy was performed. After surgery, the pregnant patient was treated with fluid and appropriate drug supplementations and continuation of the pregnancy was achieved. Adnexal torsion, though rare, should be kept in mind in the differential diagnosis of lower abdominal pain in advanced gestation.
