Encephalocele, a herniation of cranial contents beyond the normal confines of the skull, is usually classified according to the location of the skull defect [1]. Suwanwela and Suwanwela classified encephaloceles into four types, which are divided further into subtypes. Frontoethmoidal encephaloceles (FEE) type has subtypes of nasofrontal (NF), nasoethmoidal (NE), and nasoorbital (NO) [2]. Mahatumarat added “combined” subtype, defined as combination of nasoethmoidal and nasoorbital subtype [3]. Nasoorbital type is of the most infrequent type among others. The content may comprised of meninges and cerebrospinal fluid (CSF), meninges and brain parenchyma, combination of both, or involving part of the ventricle. The clinical presentation of NO FEE includes mass in the orbit, displacement of the eye, and interorbital hypertelorism. Anophthalmia or microphthalmia may occur. The authors describe cases of NE-NO, presenting with clinical sign of pulsating orbits.
