Visceral and Muscle Injuries

The important visceral and muscle injuries include:

  1. Subcapsular hematoma of the liver.
  2. Suprarenal hemorrhage.
  3. Sternomastoid Tumor:
    • It is a painless firm swelling, around 2 cm in diameter over the middle or lower third of the sternomastoid muscle.
    • Stretching of the muscle during delivery → small hematoma which heals by fibrosis.
    • In the majority of cases, it resolves spontaneously and needs nothing more than physiotherapy.
    • If it persists, torticollis occurs and may need surgical resection of the fibrous band.
