Neuroimaging of the twins. (a) Cerebral CT of twin A shows a vast lesion of cerebrospinal fluid intensity in the left temporal lobe with a maximum diameter of 63x40x26 mm. (b) & (c) MRI of twin A shows a left middle cranial fossa cystic lesion with low and high signal intensities on T1- and T2-weighted images. (d), (e) & (f) Brain CT and T1- and T2-weighted MRI of twin B shows a mirror-imaging lesion with a diameter of 30x21x5 mm with a similar intensity of cerebrospinal fluid in the right temporal lobe.

A cerebral computed tomography (CT) scan was performed showing a vast lesion of cerebrospinal fluid (CSF) intensity in the left temporal fossa with a maximum diameter of 63x40x26 mm (Fig 1a). Later magnetic resonance imaging (MRI) confirmed this observation, showing a left middle cranial fossa cystic lesion with low and high signal intensities on T1- and T2-weighted images (Fig. 1b, c). B), when the concerned parents took him to our department. Brain CT and MRI of twin B who did not have any complaints revealed a mirror-imaging of the AC in the right temporal fossa with a diameter of 30x21x5 mm (Fig 1d-f).
