A 30-year-old G2P1 at term undergoes vacuum extraction for prolonged second stage. The cup is applied 3 cm anterior to the posterior fontanelle over the sagittal suture. After delivery, the newborn develops a collection limited by cranial sutures. This describes which type of hematoma?
- A Subgaleal hemorrhage
- B Cephalohematoma ✓
- C Subdural hematoma
- D Subarachnoid hemorrhage
Correct answer: B. Cephalohematoma
Explanation
Cephalohematoma is a subperiosteal collection of blood that does not cross cranial sutures because the periosteum is firmly attached at suture lines. It is a recognized complication of vacuum extraction. Subgaleal hemorrhage crosses suture lines, spreads diffusely, and can cause massive blood loss with hemodynamic instability. Subdural and subarachnoid hemorrhages are intracranial and not limited by sutures externally.
