Unusual adverse event of tetanus: Rectus sheath hematoma

Abstract

Tetanus is a nervous system disorder characterized by muscular spasms and autonomic hyperactivity, such as unstable blood pressure. We herein report a case of tetanus in a patient in shock complicated with a rectus sheath hematoma caused by rupture of a pseudo-aneurysm of the inferior epigastric artery. A rectus sheath hematoma might be misdiagnosed as unstable blood pressure associated with autonomic hyperactivity, which is usually observed in patients with tetanus. The possibility of the occurrence of bleeding complications should be considered if a patient with tetanus has severe and persistent blood pressure reduction.
