Intramedullary tumors represent the major cause of spinal cord injuries, and its symptoms include pain and weakness. Progressive weakness may concomitantly occur in the upper and lower limbs, along with lack of balance, spine tenderness, sensory loss, trophic changes of extremity, hyperreflexia, and clonus. The study protocol was in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines.

Here, we present a patient who successfully underwent lateral cervical SCS to treat chronic refractory neuropathic pain.
Methods: A 46-year-old female, with a schwannoma involving the right axillary nerve, presented with a chronic refractory right upper extremity pain syndrome.
Introduction: Meningiomas account for 2.2% to 2.5% of all cerebral tumors, of which only 2% are located in the foramen magnum.
View Article and Find Full Text PDFBackground: Rosai-Dorfman disease (RDD) is a rare non-Langerhans cell histiocytic proliferative disorder classically as a massive cervical lymphadenopathy. However, over the years, extranodal locations were confirmed with the central nervous system involvement in less than 5% of cases, which is marked as a significant differential diagnosis of meningiomas, with which they are widely confused due to the similarity of their radiological images.
Case Description: We report a 37-year-old man and 45-year-old man who were diagnosed with intracranial RDD but whose radiological images mimic meningiomas, requiring anatomopathological and tumor's immunohistochemistry for definitive diagnosis.
Article Synopsis
- * A case is presented of a 44-year-old woman who faced severe lumbar pain and various neurological issues, eventually diagnosed with this abscess after multiple unsuccessful treatments for other conditions.
- * The report emphasizes the importance of recognizing this rare condition in patients with no apparent immunosuppression, highlighting the need for early diagnosis and surgical intervention to enhance recovery outcomes.
Article Synopsis
- A 30-year-old woman with severe occipital neuralgia experienced lead migration after starting occipital nerve stimulation therapy, attributed to fibrosis in the stress relief loop.
- Upon surgery to reposition the lead, extensive fibrosis was found, which increased tension on the lead and caused it to migrate.
- This case highlights a rare cause of lead migration, emphasizing the need for understanding its mechanisms to improve treatment outcomes.
