Onyx embolization of a ruptured rotundum foreman artery aneurysm in a patient with moyamoya disease: case report.
Hemorrhage caused by the rupture of a rotundum foreman artery pseudoaneurysm in Moyamoya disease (MMD) is rarely reported. ⋯ Given the difficulties and risks of surgery, onyx embolization of rotundum foreman artery aneurysm accompanied with MMD is feasible and effective.

Successful Management of Hemorrhage-associated Hemiballism after STN DBS with Pallidal Stimulation: A Case Report.
Deep brain stimulation has been widely used for treating several movement disorders including idiopathic Parkinson disease (IPD). The development of hemiballism after an iatrogenic injury to the subthalamic nucleus (STN) such as postoperative hemorrhage or stroke is rare. Employing pallidal DBS to manage hemiballism arising as a result of STN injury is a unique application of this therapeutic modality, which has only been reported twice in the literature. ⋯ In our case pallidal DBS was effective in treating hemiballism that arose as a result of traumatic displacement of STN DBS electrodes. Medical management and changes in stimulation parameters failed to produce any significant change in the hemiballism. This report is only the third of its kind in the literature wherein hemiballism arising as a result of STN damage after DBS was successfully treated with pallidal stimulation.
