A spinal intradural hemorrhage due to a neurinoma is very rare and requires emergency surgery. We report the first case of a spinal intradural hemorrhage due to a neurinoma in an early puerperal woman. The patient had a history of intermittent episodes of lower back pain for 3 years. The antenatal course to that time had been uneventful. Two days after a normal vaginal delivery, she presented with sudden onset of spinal lesion with severe symptoms and an emergency laminectomy was performed to remove an intradural hemorrhagic lesion due to a neurinoma. In this case, we speculate that clots in the intratumoral vessels spontaneously occurred during pregnancy and obstructions of these vessels followed by necrosis and hemorrhage of distal tissues occurred in the early postpartum stage. Moreover, the change in posture caused by the change in the maternal center of gravity following delivery, as well as the frequent bending required for the care of the newborn, may have been contributing factors. Mild but repetitive traction force caused by the change in posture and frequent bending may have created exertion on the vascular attachment to the nerve roots, causing the intradural hemorrhage.

Objectives: To assess the efficacy of endovascular treatment and clinical outcomes in individuals with symptomatic intracranial stenosis who had not responded adequately to medical intervention.
Methods: The study included 32 patients who received endovascular treatment due to high-grade (70%-99% severity) intracranial atherosclerotic stenosis from December 2021 to December 2023. The patients had not experienced any acute ischemic or hemorrhagic infarction within the last three weeks, had a Modified Rankin Scale score of ≤3 at baseline, and developed a transient ischemic attack or non-disabling stroke despite having received the best medical treatment.

Objective: The objective of this study was to discuss the characteristics of intracranial extension in patients with juvenile nasopharyngeal angiofibroma (JNA) and propose and an algorithm for its management.
Methods: A retrospective chart review of all patients with JNA who underwent operations between January 2013 and January 2023 was done, and those cases with intracranial extension categorized as stage IIIb, IVa, and IVb according to the Andrews modification of the Fisch staging classification were included in the study. Data were collected about age at presentation, symptoms, radiological findings, routes of intracranial extension, therapeutic management, and follow-up.
Epistaxis and Intradural-Extramedullary Haemorrhage in a Dog With Steroid Responsive Meningitis-Arteritis.

Article Synopsis
- A 2-year-old female Golden Retriever exhibited sudden non-ambulatory paraparesis after initially unremarkable examinations, prompting further investigation.
- MRI revealed an intradural-extramedullary mass causing significant spinal cord compression, indicating a hemorrhagic process, and CSF analysis showed signs of inflammation.
- Following surgery for decompression, the dog showed gradual improvement and regained mobility, and the diagnosis of steroid responsive meningitis-arteritis (SRMA) was supported by clinical findings and treatment response.
One-piece resection for the treatment of ventral intradural extramedullary spinal meningioma: a retrospective study.

Article Synopsis
- - The study evaluated the effectiveness of one-piece resection for treating ventral intradural extramedullary spinal meningiomas (VIESMs) by analyzing demographic and surgical data from patients treated between January 2017 and December 2023.
- - A total of 27 patients (average age 63.37) underwent the procedure, with results showing no recurrences on MRI and significant improvement in neurological status for 74.07% of the cases, although one patient faced cerebrospinal fluid leakage.
- - The findings conclude that one-piece resection is a safe and effective method for VIESMs, emphasizing techniques like maintaining a clear surgical corridor and careful dural coagulation to minimize complications and recurrence.
