Nasal cerebral heterotopia: nasal atretic cephalocele

Adult nasal gliomas

“…Nasal gliomas are differentiated from encephaloceles in that they lack anatomical communication with central nervous system tissue 4 , 5 . This gave rise to the Furstenberg test, which is typically positive when the ipsilateral internal jugular vein is compressed, and the mass enlarges and becomes pulsatile, thus differentiating encephaloceles from nasal gliomas.…”

Both Nasal Cerebral Heterotopia and Encephalocele in the Same Patient

“…It is already well accepted that nasal heterotopia are sequelae to encephaloceles (Patterson et al, 1986). Martinez-Lage et al (2002) suggested the nasal cerebral heterotopia and encephalocele form a continuum and share a common pathogenetic mechanism. In their review of 22 nasal cerebral heterotopias, Yeoh et al (1989) reported no histological features indicating communication with the brain.…”
