Abstract
Background: A 1-year-old girl was referred to the neurosurgery department. The patient presented with a swelling on the vertex of the head which was present at birth but increased gradually over time. There were no perinatal problems and the child developed normally. The swelling produced no discomfort nor pain, and measured 2 cm Å~ 3 cm. The child was followed during 6 months because there was a chance of involution. The patient was reevaluated 6 months later.
