Facial abnormalities include turribrachycephaly, flattened midface, hypertelorism, cleft palate, bilateral cleft lower lip, supernumerary teeth, macrostomia, short neck with limited range of movement and two separate, fully formed, independently moving tongues - double tongue [Figure 1a].

Head MRI reveals duplication of multiple midline structures: two sellas and two pituitary glands, a duplicate ventricular system, two basilar arteries and a midline third cerebral peduncle [Figures 2a-c and 3a, b].
T1 weighted MRI with contrast of associated cranial abnormalities (a) axial image of midline third cerebral peduncle (b) coronal image demonstrating fenestration of basilar artery, agenesis of corpus callosum

Head MRI reveals duplication of multiple midline structures: two sellas and two pituitary glands, a duplicate ventricular system, two basilar arteries and a midline third cerebral peduncle [Figures 2a-c and 3a, b]. Her imaging is also notable for agenesis of the corpus callosum and a clival encephalocele Figure 3 with an adjacent midline nasopharyngeal tumor consistent with residual teratoma [Figure 4].
Midline saggital T1 weighted MRI with contrast: defect in the clivus is observed with accompanying encephalocele. Naso-pharyngeal teratoma also observed

The craniocervical junction appeared abnormal with a widened C1 arch, C2 body duplication and two odontoid processes [Figure 5].
