Absence of the common carotid artery (CCA) is a rare anomaly. In the few cases described in the literature, it has been typically associated with separate origins of the internal carotid artery (ICA) and external carotid artery (ECA) Fife (1921), Boyd (1934), Rossiti and Raininko (2001), Cerase et al. (2009), Drazin et al. (2010), Yim et al. (2009), Monaco et al. (2009), Jerius et al. (1995), Dahn et al. (1999), Cakirer et al. (2002), Choi et al. (2015), Bryan et al. (1978), Horowitz et al. (2003), Roberts and Gerald (1978), Rajeshwari (2013), Purkayastha et al. (2006), Maybody et al. (2003), Wood et al. (2011) . To the best of our knowledge, absence of the CCA without separate origins of the ECA and ICA has only been described five times before, one of them in conjunction with a persistent proatlantal intersegmental artery (PIA) Cao et al. (2011) and four with agenesis of the ICA Kobayashi et al. (2013), Kunishio et al. (1987), Chen et al. (2008), Xie et al. (2010) . We present a case of a previously undescribed variation of this rare vascular anomaly.
