متن کاملIsolated abducens nerve palsy caused by contralateral vertebral artery dolichoectasia.
hematological investigations were all within normal limits. Magnetic resonance (MR) imaging and MR angiography of the brain and orbit demonstrated compression of the right abducens nerve superiorly and laterally by dolichoectatic left VA. No other abnormal signals were seen in brainstem [Figure 1]. Owing to the fact that the right abducens nerve palsy was mild and the patient showed no diplopia...
متن کاملVertebral artery compression of the medulla.
BACKGROUND Intracranial arteries in the subarachnoid space may compress the brain parenchyma and cranial nerves. Most arterial compressive lesions have been attributed to dolichoectasia in the vertebral-basilar system, and prior reports have concentrated on the pressure effects of basilar artery ectasia. Much less is known about vertebral artery compression of the medulla. OBJECTIVE To descri...
متن کاملDolichoectatic basilar artery: a review of 23 cases.
The dolichoectatic basilar artery was found in 23 cases during a 10-year period. The 19 males and 4 females ranged in age from 30 to 69 years (mean: 55 years). Hypertension was noted in 17 patients. In seventeen (74%) of the present cases this anomaly could be visualized with CT scan. Seven patients (30%) presented with pontine infarction, which was identified on CT scan in all cases. Vertebro-...
