Background: Pseudotumors are rare lesions that may cause compression of adjacent neural structures. Treatment options range from conservative management to surgical intervention.
Case description: A 59-year-old female presented with a 3-month history of headaches, difficulty speaking, swallowing, gait disturbance, and progressive left-sided weakness. Her examination confirmed left-sided tetraparesis. The cervical magnetic resonance showed a right-sided mass compressing the bulbomedullary junction. Through a modified right-sided far lateral craniotomy, an intradural "pseudotumor" was removed. Postoperatively, the patient's symptoms gradually improved. Histopathological analysis revealed an acellular fibrocartilaginous mass consistent with the diagnosis of pseudotumor.
Conclusion: Pseudotumors at the craniocervical junction may cause progressive tetraparesis readily resolved following gross total surgical excision.
