Proboscis lateralis (PL) is a rare craniofacial anomaly with a reported incidence of less than 1 in 100 000.1 Given the rarity of this condition, there is a paucity of reports documenting the characteristic appearance of this anomaly on physical examination and radiologic imaging. We present a case of PL evaluated with computed tomography (CT) and magnetic resonance imaging (MRI) and review salient features of this rare condition.
