Spontaneous resorption of calcified cephalhematoma in a 9-month-old child: case report

Cephalhematoma is a subperiosteal collection of blood in newborns, mostly caused by birth injury [7]. It usually develops in the parietal eminence and does not cross suture lines. Most cephalhematomas spontaneously resorb within a month but they may calcify if they do not resorb beyond this time [5, 11]. Calcified cephalhematomas are classified into two types, based on the contour of the inner calvarial bone in relation to the surrounding normal cranial vault [17]. Type 1 has a nondepressed inner bone without encroachment into the cranial cavity and type 2 has a depressed inner bone into the cranial cavity. Calcified cephalhematoma causing skull deformitymay require surgical reconstruction if it develops 1 month after delivery. However, the cranial vault may remodel as skull grows even in cases of calcified cephalhematoma. To date, there is one report regarding calcified cephalhematoma causing skull deformity with spontaneous resolution [4]. Herein, we report a case of type 1 calcified cephalhematoma causing skull deformity in a 3-month-old boy, which spontaneously resorbed in 6 months and discuss treatment options for this rare condition.
