title: Calcified cephalohematoma as an unusual cause of EEG anomalies: case report.
abstract: Cephalohematoma, one of the most common neonatal head injuries, generally undergoes spontaneous resorption. When calcified, it may cause cranial vault distortion and depression of the inner skull layer, although it remains asymptomatic. Surgery, indeed, is usually performed for cosmetic purposes. For these reasons, the long-term effects of calcified cephalohematoma (CC) are widely unknown. The authors report the case of an 11-year-old girl with a persistent calcified CC causing skull deformity and delayed electroencephalography (EEG) anomalies. These anomalies were detected during routine control EEG and were not clinically evident. The young girl underwent surgical removal of the CC for cosmetic purpose. The EEG abnormalities disappeared after surgery, thus reinforcing the hypothesis of a correlation with the brain "compression" resulting from the CC. To the best of the authors' knowledge this is the first time that CC-associated EEG anomalies have been described: even though these anomalies cannot be considered an indication for surgery, they merit late follow-up in case of skull deformity.
