CEPHALHEMATOMA is a common condition in the neonate, reported to affect boys more commonly than girls and the right parietal bone more commonly than the left.1 Neonatal osteomyelitis of the calvaria, on the other hand, is a relatively rare condition.2-6Gardnerella vaginalis is an organism of low virulence and invasiveness that is associated with nonspecific vaginitis.7 The following case report describes a patient with cephalhematoma, right parietal osteomyelitis, a scalp aspirate revealing gram-negative pleomorphic rods, and a positive placental culture of gram-negative rods resembling G vaginalis.

Report of a Case  A male infant weighing 4080 g was born at 43 weeks' gestational age to a 17-year-old primigravida after induction of labor with oxytocin.
