“…In a minority of cases, intrauterine events have been thought to contribute to this malformation. Axton and Levy9 suggest that the most frequent mechanism may be occult trauma from pressure of the fetal head on the sacral promontory, resulting in moulding. Other mechanisms include pressure on the soft fetal skull from the maternal fifth lumbar vertebrae, pubic symphysis, ischial spines, asymmetric or contracted pelvis, fetal limbs, and uterine myomas 10 11…”

Congenital depression of the skull in a neonate

et al. 2016

Congenital depression of the fetal skull is a rare condition. We discuss the case of a 14-days-old male infant, born at term by elective non-complicated caesarean section presenting with a left temporoparietal skull depression. A CT scan was performed which showed no associated fracture. A conservative approach was followed since the infant showed no signs of neurological deficit. Similar cases have been managed successfully in other reports using a conservative approach, with the condition being often self-resolving over the course of a few months.

“…The incidence of depressed skull fracture in neonates observed immediately after birth is very rare, ranging from 1/4,000 [3] to 1/10,000 [4], Delivery trauma or ab dominal trauma of the mother during pregnancy can be a cause of depressed fracture [1-3, 6, 12]. In some cases with unknown cause, the promontory of the sacrum [2,3], fibroma of the uterus [2,4], and exostosis of the lumbar vertebra [2] have been reported to be responsible for depression of the skull.…”

“…In some cases with unknown cause, the promontory of the sacrum [2,3], fibroma of the uterus [2,4], and exostosis of the lumbar vertebra [2] have been reported to be responsible for depression of the skull. According to the literature, depressed fracture of infant's skull has been reported to occur as a result of contact of the skull against the promontory of the sacrum.…”

“…Two surgical methods have been reported: (1) the routine method is to expose the depression and repair the frac tured region as a free bone [7], and (2) the other method is to insert a periosteal elevator through a burr hole made around the depression and to elevate and repair it [3,8]. In the case of intrauterine depressed fracture, depression usually occurs in the frontal bone and the bregmatic fontanel is open.…”

Intrauterine Depressed Skull Fracture

et al. 1989

View full text Add to dashboard Cite

Two cases of intrauterine depressed fracture are presented. In each case, the mother had no history of abdominal trauma during pregnancy, the children were delivered normally without the use of forceps, but a round depression was present in the left frontal bone at time of delivery. CT scans demonstrated a depressed fracture of the left frontal bone and stagnation of cerebrospinal fluid around the fracture. Elevation of the depression was therefore made through a small incision along the rear edge of the frontal bone using a periosteal elevator. A review of intrauterine depressed skull fracture is made and the concept, mechanism, surgical indications and operative methods of this rare fracture are discussed.

“…Prenatal moulding of a calvarial bone has occa sionally been shown to result from maternal abnor malities, such as a uterine fibroid (BARR 1952), but may be caused also by the fetal limbs. When examin ing a newborn baby with congenital bilateral impres sion of the forehead and slight malformation of the feet, BROWNE noticed that, on extension of the legs and flexion in the hip joints, each foot thus brought into contact with the forehead fitted into the ipsilateral concavity of the skull.…”
