Spontaneous Rectus Sheath Hematoma During Pregnancy Mimicking Abruptio Placenta

Abstract

Sudden disruption of a deep epigastric vessel may result in an abdominal wall hematoma, which, depending upon its location and size, can produce symptoms and clinical findings compatible with a variety of acute intra-abdominal conditions. The literature has noted a predominance of pregnant patients among those affected with this malady. Such hematomas are infrequently encountered and early accurate diagnosis could prevent surgical intervention. Unfortunately, the clinical manifestations of rectus muscle hematoma are sometimes so dramatic that laparotomy is performed under the belief that intra-abdominal pathology is present. We present a case of a suspected abruptio placenta misdiagnosed by clinical and ultrasound examination that was subsequently discovered to be a rectus sheath hematoma at the time of surgery.
