[Anatomo-radiologic correlations in spontaneous hematoma of the rectus abdominis muscles].

Purpose: Rectus sheath hematomas are a frequent but sometimes misdiagnosed disease in patients under anti-coagulative drugs, hemodialysis, or simply in the elderly. The most frequent localization is in the lower part of the abdomen: the explanation lies in the anatomy of the abdominal wall, especially in the arcuate line of the rectus sheath. Aim of this work is to explain the reason of the almost constant location correlating the anatomy with the CT features.
