The etiology, pathogenesis, and optimal treatment strategies for this condition remain undetermined. The occurrence of spontaneous spinal epidural hematoma (SSEH) in the context of JAK2 V617F-positive myeloproliferative neoplasms (MPNs) represents a rare manifestation. Magnetic Resonance Imaging (MRI) plays a crucial role in the definitive diagnosis of this condition. With a good understanding of the pathogenic characteristics and clinical presentations of this disease, a diagnosis can be reasonably made, even in the absence of MRI, based on physical examinations indicating the affected area. Once diagnosed, immediate surgery is recommended to attempt the restoration of spinal cord function. Postoperatively, the use of hydroxyurea has proven effective in disease control.Case Presentation: We report a case of a 65-year-old male patient who presented with progressive lumbar back pain and bilateral lower limb paralysis lasting for 36 hours. CT imaging revealed an intraspinal lesion at the L1-3 level, and genetic testing confirmed the presence of the JAK2V617F mutation. Following surgery, there was a significant recovery of sensory and motor function in the lower limbs. At one-year follow-up, the patient demonstrated good functional status, and blood tests indicated a platelet count within the normal range.Conclusion: The presented case adds to the existing literature on SSEH by highlighting the association with myeloproliferative neoplasms (MPNs), as evidenced by the JAK2V617F mutation. MPNs constitute a group of hematologic malignancies, and the association with SSEH is a rare occurrence. The exact interplay between MPNs and SSEH warrants further investigation, as the underlying mechanisms linking these conditions remain elusive. The case also underscores the importance of a multidisciplinary approach, involving hematologists and neurosurgeons, in the comprehensive management of such complex cases.Keywords: myeloproliferative neoplasms, spinal epidural hematoma, JAK2V617F |
