Abstract

|
|
|
Pilocytic astrocytoma is most often a benign and low-grade tumor with a favorable prognosis. This report presents the case of a 24-year-old woman with rapidly progressive weakness of the bilateral lower extremities. The manual motor test was Grade I. She underwent thoracic laminoplasty from level T2 to T8 and a lesionectomy was performed in our department. Despite surgical intervention, the lower extremity weakness deteriorated to Grade 0. Serial magnetic resonance imagings (MRIs) revealed that the tumor mass was recurring and that syrinx expansion was further contributing to the spinal cord compression. Two years later, this patient presented complaining of upper extremity weakness. On the MRI scan, the syrinx was further expanded and cord signal change of the cervical spine was noted. Revision laminoplasty was performed with a massive spinal lesionectomy from T1 to T12 under intraoperative neuro-monitoring. Radiation therapy of the entire spinal cord was performed to prevent further recurrence following surgery.
