Abstract

We report the sargical outcome of spinal subpial lipoma in four cases without adult-onset spinal bifida. [Case 1] A 20-year-old female complained of mild weakness (MMT [4]) of the left lower extremity and urinary hesitancy. MRI revealed spinal subpial lipoma. Laminectomy from T3 to T8 was performed. After tumor biopsy, duraplasty using autologous fascia lata was performed. Postoperatively, MMT for the left lower extremity improved to [5]. Independent ambulation became stable, and urinary hesitancy disappeared. [Case 2] A 46-year-old female complained of weakness of the right lower extremity. The patient was diagnosed with spinal subpial lipoma with thoracic scoliosis. Laminectomy from T1-T9, biopsy, and duraplasty using artificial dura mater were performed. After surgery, ambulation became stable and she returned to her previous job as a waitress 10 months after surgery. [Case 3] A 27-year-old female complained of numbness and weakness in both lower extremities. Laminectomy from T8 to T12, biopsy, and duraplasty using artificial dura mater were performed. Numbness and weakness in both lower extremities improved. [Case 4] A 48-year-old female complained of numbness in the left upper and lower extremities. Partial tumor resection at C1-C2 was done, but position sense disturbance manifested postoperatively.
