To analyze the outcome of epileptic patients who had redo surgery involving the vagus nerve stimulation's lead. ⋯ Complete removal or replacement of the VNS system including the lead and the electrode is feasible and safe. These procedures should be offered to patients who would no longer benefit from the VNS or when only a lead change is needed.

Racial disparities have been shown to affect surgical outcomes. However, the effect of race on complex spinal fusion outcomes remains understudied. The aim of this study is to determine if patient race affects 30-day complication rates after elective complex spinal fusion (≥5 levels). ⋯ Our study suggests that there is no difference between races in 30-day complication and readmission rates after complex spinal surgery requiring ≥5 levels of fusion.

Case Reports
Trigeminal Ganglioneuroma: A rare cause of trigeminal neuralgia caused by cerebello-pontine angle tumor.
Intracranial ganglioneuromas are very rare benign tumors of neural crest origin and generally arise from the peripheral nervous system or adrenal glands. Very few cases of intracranial ganglioneuroma arising from the trigeminal nerve have been reported in the literature, all in East Asia. ⋯ To the best of our knowledge, this is the sixth case of trigeminal ganglioneuroma; however, it is the first case reported in the United States.

Case Reports
Spontaneous Intraventricular Hemorrhage: A Rare Presentation of a Skull Base Mesenchymal Chondrosarcoma.
Chondrosarcomas are very rare malignant, slow-growing tumors that develop in or near the petroclival region of the brain. We report a very rare case in which the tumor originated from left petrous bone and induced intraventricular hemorrhage leading to an acute comatose presentation. ⋯ Our experience of petroclival junction chondrosarcoma causing intraventricular hemorrhage may be the first to be documented. Preferred treatment of this highly malignant lesion is radical removal with postoperative radiotherapy.

Case Reports
Delayed development of aneurysms following gamma knife surgery for trigeminal neuralgia: report of 2 cases.
Delayed development of intracranial aneurysms is an extremely rare complication of gamma knife surgery (GKS), with only 6 cases been reported to date. There are no reported cases after GKS performed to treat trigeminal neuralgia (TN). Of the 6 aforementioned cases, none referred to the natural history or pathophysiology of GKS-related intracranial aneurysm formation. ⋯ Long-term observations are necessary after GKS performed for TN owing to the possibility of formation of intracranial aneurysms near the irradiated region.
