Torsion of giant occipital encephalocoele in a 2-day-old infant: emergent surgery and outcome.

Necrosis may have resulted from arterial or venous compromise caused by torsion of the pedicle during delivery or after birth. The high pressure inside the sac associated with the thin skin of the encephalocele may be another predisposing factor. In view of the risk of meningitis and rupture, immediate surgery with repair with minimal blood loss is indicated.
