AbstractA 56-year-old male was admitted in January 1994, with back pain persisting for 2 months. Magnetic resonance imaging disclosed a homogeneously enhanced mass occupying the spinal canal at the T-8 level and extending into the retropleural space through the left intervertebral foramen between T-8 and T-9. The diagnosis was a thoracic dumbbell-shaped neurinoma. The tumor was successfully removed through a posterolateral approach using hemilaminectomy and partial costotransversectomy with preservation of ipsilateral joint facets. Histological examination indicated neurinoma. This approach allows excellent visualization of anterior paraspinal components of the tumor, preserves important anatomic structures, and requires minimal compression of the cord for removal of the lesion.
