Introduction
Torsion of a giant occipital encephalocele leading to necrosis is an extremely rare complication found in neonates with only two such cases reported in literature previously. Infection and ulceration of the necrosed skin may lead to meningitis or sepsis. We present here a neonate with giant occipital encephalocele showing progressive necrosis during the first day of his life.
Case report
A new-born baby, delivered vaginally, with no antenatal imaging was found to have a huge mass in the occipital region, which was covered by normal pink-purplish skin. During the first day of his life, the sac started becoming ulcerated accompanied with a rapid colour change in the skin, gradually turning darker and then black. The pedicle of the encephalocele was twisted with progressive necrosis of the encephalocele. MRI showed a giant encephalocele with single vein draining into the torcula and dysplastic occipital lobe herniating into the defect. The neonate was taken up for urgent excision and repair of the encephalocele. The encephalocele was excised ‘in-total’ with ‘figure-of-8’ repair of the meninges. One year after the operation, she appears to be well-developed without any neurological problems.
Conclusion
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.
