Review Case Reports
Isolated Oculomotor Nerve Palsy As The First Presenting Symptom of Bilateral Chronic Subdural Hematomas: Two Consecutive Case Report and Review of the Literature.
Isolated oculomotor nerve palsy (ONP) is caused most commonly by vascular disease, posterior circulation aneurysms, and inflammatory or traumatic injury. ONP usually occurs in chronic subdural hematoma (CSDH) as a common sign of cerebral herniation that typically is associated with a deterioration of consciousness. ⋯ Although isolated ONP is a very rare presentation of CSDH, a differential diagnosis is absolutely necessary, because surgical treatment allows good recovery of third nerve palsy in most of the cases.

Comparative Study Controlled Clinical Trial
Comparison of Primary Spinal Central and Peripheral Primitive Neuroectodermal Tumors in Clinical and Imaging Characteristics and Long-term Outcome.
Primary spinal primitive neuroectodermal tumors are extremely rare entities. The purpose of this study was to analyze the differences in clinical and imaging characteristics and outcomes between primary spinal central PNETs (cPNETs) and peripheral PNETs (pPNETs). ⋯ Patients with spinal cPNETs were younger compared with patients with pPNETs. The prognosis of spinal cPNETs and pPNETs was poor with no significant difference between the entities. The most beneficial treatment modality is GTR combined with adjuvant radiotherapy and chemotherapy.

Review Case Reports
Isolated Intramedullary Spinal Rosai-Dorfman Disease: A Case Report and Literature Review.
Rosai-Dorfman disease (RDD) is a rare histioproliferative disorder that only occasionally involves the central nervous system. ⋯ Preoperative diagnosis of spinal RDD is still challenging because the lesion usually is a dura-based lesion that mimics a meningioma. Surgical resection is an effective treatment and radiotherapy; and steroid and chemotherapy have not demonstrated reliable therapeutic efficiency.

Review Case Reports
Thoracolumbar Arteriovenous Malformations Presenting with Intracranial Subarachnoid Hemorrhage: Case Series and Review of Literature.
Cryptogenic intracranial subarachnoid hemorrhage accounts for approximately 15% of all subarachnoid hemorrhage cases. Diagnostic workup after negative cerebral digital subtraction angiogram typically includes magnetic resonance imaging of the brain and cervical spine for arteriovenous malformations, tumors, and fistulae. Only a few cases of thoracolumbar spinal vascular malformations have been associated with intracranial subarachnoid hemorrhage. ⋯ In younger populations presenting with nonaneurysmal intracranial subarachnoid hemorrhage and symptoms related to the spinal cord, evaluation for thoracolumbar spinal vascular malformations must be included in the initial workup.

Review Case Reports
Isolated, transient, pneumocephalus-induced oculomotor neuropathy after microvascular decompression of the trigeminal nerve.
Pneumocephalus is a common radiographic finding after posterior fossa craniotomy. In contrast, cranial neuropathies related to pneumocephalus are extremely rare, with only a handful of previous reports. ⋯ Cranial neuropathy secondary to pneumocephalus is a rare and usually self-limiting condition. Although high-concentration oxygen therapy hastens resolution of pneumocephalus, recovery from pneumocephalus-related neuropathies may take weeks to months. To properly treat pneumocephalus-induced cranial neuropathies, further studies into the mechanism of injury are needed.
