But, contral- ateral internal carotid artery origin has not been mentioned in this review article. In our patient, the origin of contralateral ophthalmic artery was infrachiasmatic. When any stenosis or occlusion occurs in the ICA or common carotid artery, ipsilateral ocular symptoms can be seen, except for neurological findings. In our patient, although we determined the occlusion in right ICA, vision loss was not detected. Dandy–Walker variant is a less severe brain anomaly than Dandy–Walker malformation. There is usually partial hypoplasia of the cerebellar vermis with partial obstruction to the fourth ventricle, but without enlargement of the posterior fossa. The majority of patients with Dandy–Walker variant are sporadic. 18 Magnetic resonance imaging shows dilatation in lateral and third ventricle, hypoplasia of cerebellar vermis, and cystic dilation communicating with the fourth ventricle. 19 Differential diagnosis of the cystic malformations of the posterior fossa has been radiological extensively addressed. Magnetic reson- ance imaging may not provide sufficient anatomic information in the diagnosis of the cystic lesions of the posterior fossa. Moreover, membranes associated with these cysts cannot often be visualized by conventional MR imaging. Phase-contrast MR imaging provides noninvasive evaluation of intracranial cerebrospinal fluid (CSF) flow patterns, and clearly depicts flow communication between CSF containing compartments such as Dandy–Walker complex, mega- cisterna magna, and arachnoid cyst. 20 In our patient, because the patient could not tolerate a CSF flow MR imaging, we could not perform CSF flow examination with phase-contrast MR imaging. Hydrocephalus is often associated with Dandy–Walker com- plex. In these patients, aquaductal stenosis or occlusion may pre- sent. Cardiac-gated cine MR sequence is useful in the assessment of the aqueduct for patency. 20 The diagnosis of additional cranial anomalies is associated with a poor outcome regardless of the type of posterior fossa anomaly. 21 Normal neurodevelopmental outcome in prenatal and postnatal series shows wide variety. However, neurodevelopmental delay has been notified in 40% to 60% of children with Dandy–Walker complex, with the worse outcome. 20,21 Because of associate anomalies, termination rates were very high in Dandy–Walker malformation/variant. 20 CONCLUSION We presented that the right OA originated from the supraclinoidal segment of the left ICA. It lied into the right optic channel and orbita. Moreover, Dandy–Walker variant was together with this very rare anomaly. To our knowledge, this togetherness is the first patient in English literature. In determining variations of OA (as in our patient), the diagnostic value of MR angiography is high and can be used in routine examinations. In daily radiological practice, the radiologists should perform a very careful assessment in patients with possible anatomical variations. REFERENCES 1. Fawcett E.
