Pediatric posterior cerebral artery stroke as a presentation of atlantoaxial dislocation.

Nandish HS, Borkar SA, Kale SS, Sharma BS, Mahapatra AK - J Pediatr Neurosci (2015 Apr-Jun)

Bottom Line: Plain dynamic radiography showed reducible AAD and intra-arterial digital subtraction angiography demonstrated occlusion of left posterior cerebral artery.Vertebrobasilar insufficiency is a known entity in a patient with reducible AAD; however, isolated involvement of posterior cerebral artery is very rare.So this condition should be kept in mind, and necessary interventions must be undertaken at the earliest to avoid further irreversible brain damage.

ABSTRACT
We report an uncommon case of posterior circulation stroke in a young patient due to occlusion of posterior cerebral artery with reducible atlantoaxial dislocation (AAD). Plain dynamic radiography showed reducible AAD and intra-arterial digital subtraction angiography demonstrated occlusion of left posterior cerebral artery. Patient underwent stabilization of craniovertebral junction by occipito cervical fixation using occipit-C2/C3 lateral mass screws and rod fixation and has since experienced no recurrent symptoms. Vertebrobasilar insufficiency is a known entity in a patient with reducible AAD; however, isolated involvement of posterior cerebral artery is very rare. So this condition should be kept in mind, and necessary interventions must be undertaken at the earliest to avoid further irreversible brain damage.

Mentions: Dynamic X-rays of the cervical spine with CVJ revealed reducible AAD [Figure 3]. Non-contrast computed tomography cervical spine with CVJ showed occipitalized atlas with block vertebrae of C2/C3 and C6/C7 with mild kyphoscoliosis with AAD [Figure 4].
