Spontaneous resolution of atraumatic intrauterine ping-pong fractures in newborns delivered by cesarean section.

Two cases of spontaneous intrauterine ping-pong fractures are reported in newborns delivered by cesarean section. Skull fractures occurred with no evidence of extrinsic trauma or cephalopelvic disproportion. Subsequent clinical follow-up at 6 and 12 months revealed normal skull reshaping and growth, with no associated neurological deficits. Spontaneous intrauterine ping-pong fractures in newborns delivered by cesarean section is a distinctly rare condition. These 2 cases demonstrate that, even without complicated spontaneous vaginal delivery or history of external trauma, congenital ping-pong fracture of the skull can occur. The existence of this clinical condition and its spontaneous resolution is important knowledge that can assist in the prepartum and postpartum management of children with this pathology.
