Occult traumatic avulsion of an ovarian dermoid cyst

This case report describes a unique presentation involving avulsion of an ovarian dermoid tumor which occurred as the result of blunt trauma secondary to a motor vehicle collision. Despite an unimpressive initial presentation and normal physical examination, the patient subsequently developed symptoms of severe hemorrhage requiring aggressive intravascular volume resuscitation. A ruptured ovarian dermoid tumor was eventually diagnosed by computerized axial tomography. A review of the literature by the authors did not reveal any similar cases of previous reports of this phenomenon.
