====== Subgaleal hematoma differential diagnosis ======

[[Subgaleal hematoma]] may cross [[cranial suture]]s. Inexperienced clinicians may suspect [[CSF]] collection under the [[scalp]] which does not occur. Usually presents as a soft, fluctuant mass. These do not calcify.

===== Subperiosteal hematoma =====
 

[[Subperiosteal hematoma]] (some refer to this as [[cephalhematoma]]): most commonly seen in the newborn (associated with parturition, may also be associated with neonatal scalp monitor)

Osteomyelitis and Epidural Abscess: A Delayed
Complication of Fetal Monitoring. Pediatr Radiol.
1986; 16:150–151))
((Kaufman HH, Hochberg J, Anderson RP, et al.
Treatment of Calcified Cephalhematoma.
Neurosurgery. 1993; 32:1037–1040))
Bleeding elevates periosteum, extent is limited by sutures. Firmer and less ballotable than [[subgaleal hematoma]]
((Matson DD. Neurosurgery of Infancy and
Childhood. 2nd ed. Springfield: Charles C Thomas;
1969)); 
scalp moves freely over the mass. 80% reabsorb, usually within 2–3 weeks.
Occasionally may calcify
