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.

Although glioblastoma is the most common primary brain tumor, primary intraventricular locations are extremely rare; only 21 cases have been reported to date. ⋯ Intraventricular glioblastoma is extremely rare and can affect younger individuals including children. This malignant tumor should be included in the differential diagnosis of intraventricular lesions, especially in the lateral ventricles. Radical surgical resection can be associated with remarkable disease-free survival, especially in isocitrate dehydrogenase-mutated tumors. Because recurrence virtually is unavoidable, long-term follow-up is mandatory.

Review Case Reports
Dislocated pacemaker electrode simulating focal epileptic state in a patient with subdural hematoma - Case report and review of the literature.
Due to demographic changes, the number of patients with traumatic brain injury carrying a cardiac resynchronization therapy device is increasing. One of the common complications of subdural hematoma (SDH) is epilepsy, whereas one of the most frequent early complications after cardiac resynchronization therapy device implantation is lead dislocation. The latter might then cause unintended skeletal muscle stimulation that might be misinterpreted in seizure-prone patients. ⋯ In case of refractory treatment of epilepsy, dislocation of pacemaker electrodes is a, most certainly, rare but possible differential diagnosis. Confirmation of electrode position and function is easily and quickly feasible and will help prevent futile seizure-directed therapy.

Review Case Reports
Neuroinflammation preceding and accompanying primary central nervous system lymphoma: case study and literature review.
Primary central nervous system lymphoma (PCNSL) is an aggressive lymphoma confined to the CNS. Although the pathogenesis of PCNSL in immunocompetent individuals remains unclear, there have been several case studies demonstrating the "sentinel" inflammatory lesions months before the manifestation of PCNSL. However, the pathologic relationship between the inflammatory lesions and subsequent PCNSL is still unknown. ⋯ PCNSL may be preceded and accompanied by an inflammatory process that is pathologically distinct from PCNSL. Our case study, in combination with a review of previously published similar cases, supports the hypothesis that the "sentinel" inflammatory lesions may be the first immune response against PCNSL.

Review Case Reports
Microvascular Decompression for Oculomotor Nerve Palsy: A Case Report and Literature Review.
Oculomotor nerve palsy can result as a manifestation of diabetic mellitus or aneurysmal compression. Vascular loop compression is a very rare etiology of oculomotor nerve palsy. Here, we present a case report of microvascular decompression for oculomotor nerve palsy. ⋯ Vascular compression of the oculomotor nerve is a very rare finding in neurosurgical practice. A diagnosis of vascular compression is made by excluding other pathologies and using high-resolution images that visualize the nerve and the offending vessel loop. Microvascular decompression can be an effective treatment method for this condition.
