Rectus sheath hematoma

Planning

Indications

Main risk factors are:

  • Hypocoagulability, such as anticoagulant medication
  • Trauma

Choice of modality

IV contrast

For follow-up of a known muscular hematoma, it is sufficient to perform CT without IV contrast.[notes 2] If detection of contrast extravasation or active bleeding is specifically requested, an arterial phase contrast CT is preferred.[1]

Evaluation

  • Location
  • Size
  • If contrast CT, any visible contrast leakage

  2. A contrast CT can detect extravasation of contrast material, but this does not seem to be correlated to clinical severity, as evidenced from rectus sheath and iliopsoas hematomas.
