Successful relief of central poststroke pain with BurstDR spinal cord stimulation: A case series.

Background: Central poststroke pain (CPSP) is a commonly undertreated condition that can negatively impact a patient's quality of life. The efficacy of spinal cord stimulation (SCS) for the treatment of CPSP is not established due to limited studies. Case Description: Here, two patients, ages 42 and 75, sustained strokes resulting in CPSP. After failed medical management, both underwent placement of paddle-lead SCS systems utilizing BurstDR stimulation that successfully resulted in pain resolution. Conclusion: Two patients with CPSP were successfully treated with paddle lead SCS with BurstDR programming.

Trigeminal nerve hemangioblastoma in the setting of undiagnosed von Hippel-Lindau disease: illustrative case.

BACKGROUND: Von Hippel-Lindau disease (VHL) is an autosomal dominant tumor predisposition syndrome caused by mutations in the VHL gene. Patients with VHL are predisposed to developing numerous neoplasms, including central nervous system hemangioblastomas that typically arise within the cerebellum, brainstem, or spinal cord. The authors present the unusual case of a 69-year-old patient with a hemangioblastoma of the trigeminal nerve as his initial presentation of VHL. OBSERVATIONS: A 69-year-old male presented with progressive right-sided V3 paresthesias, gait disturbance, and diplopia. Magnetic resonance imaging demonstrated an enhancing 0.5-cm nodule within the right trigeminal nerve and an associated peritumoral cyst exerting mass effect on the cerebral peduncle. Neural axis imaging demonstrated pia-based enhancing lesions concerning for multiple spinal hemangioblastomas. The patient underwent an uncomplicated retrosigmoid craniotomy for trigeminal nerve hemangioblastoma resection. The patient had postoperative improvement in his gait, diplopia, and facial paresthesias. Genetic testing revealed that the patient was heterozygous for a pathological mutation in the VHL gene. LESSONS: Hemangioblastomas in adults over 50 years of age should prompt a workup for VHL. Recognizing that cranial nerves are a possible site of hemangioblastoma occurrence is important for neurosurgeons and radiologists alike. Resection of cranial nerve hemangioblastomas is technically challenging but can lead to symptom improvement for patients. https://thejns.org/doi/10.3171/CASE24149.
