Cervical intra-extradural meningioma with en-plaque, dumbbell-shaped, and an unusual calcified pattern in a young patient

Abstract

Background: Most spinal meningiomas primarily grow in the intradural extramedullary location. Epidural meningiomas are uncommon; if detected, they usually coexist with intradural lesions. They inhere more aggressive and invasive characteristics compared with their counterparts inside the dura. Case Description: We report a 22-year-old female who was admitted to the hospital with weakness and numbness in both lower limbs. Her cervical magnetic resonance imaging revealed an en-plaque and dumbbell-shaped lesion located from C5 to C8. After gadolinium injection, the whole mass was enhanced and unveiled two portions: intradural and extradural. The bone window of the computed tomography scan revealed calcification inside the lesion. The patient underwent tumor removal surgery. The pathology findings showed a psammomatous meningioma. After 6 months of surgery, the patient has been able to walk with walkers. Conclusion: We should consider spinal meningioma as a differential diagnosis when encountering an extradural lesion in the cervical region. The optimal surgical treatment for young patient with epidural meningiomas is radical surgery with dura attachment removal.
