MRI diagnosis of occipital cephalohematoma mimicking an encephalocele

Calcified cephalohematoma as an unusual cause of EEG anomalies: case report

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.

Bathrocephaly: A Head Shape Associated with a Persistent Mendosal Suture

Bathrocephaly, a deformity of the posterior skull with bulging of the midportion of the occipital bone, is often associated with a benign variant of the mendosal suture ( Mulliken and Le, 2008 ). The endochondral and membranous portions of the occipital bone converge at the mendosal suture, which normally closes during fetal life or early infancy. When it persists, it is associated with a characteristic head shape that requires no intervention. We review the clinical findings associated with postnatal persistence of the mendosal suture and discuss other factors that may be associated with bathrocephaly.
