Torcular occipital encephalocele in infant: Report of two cases and review of literature

Abstract

The presence of torcula or sinus in the occipital encephalocele presents a challenge during surgery. However, a detailed study of magnetic resonance image and magnetic resonance venography can aid in preoperative localization of the torcula. Knowing the encephalocele's contents, its relationship with falx cerebri and falx cerebelli, and vigilance during surgery is a sure way to protect neural tissue. Visual Evoked Potential (VEP) may be indicated in torcular encephalocele. Here, authors report two such cases, one presented with ruptured encephalocele with cerebrospinal fluid leak and another case presented six months after birth due to financial constraints. Pertinent literature and management is briefly reviewed.
