Complex dumb-bell spinal tumors are challenging surgical lesions. Combined antero-posterior exposures have traditionally been used in their management. This combined exposure has the disadvantage of a two-stage operation with transthoracic or retroperitoneal dissection. With better understanding of biomechanics of spine and evolution of microsurgical technique, there has been resurgence of single stage surgeries, among which the transparaspinal exposure provides the simplest and the most direct route for resection of dumb-bell tumors. A 16-year-old male was admitted with history of back pain with radiation to left lower limb for 6 months, progressive weakness of both lower limbs for two months, and hesitancy of micturition for 1 month. A clinical diagnosis of cauda-conus lesion was made. Radiological investigations revealed a complex dumb-bell spinal tumor extending from lower part of L2-L4 vertebra, with large paraspinal extension through left L3 intervertebral foramina. Tumor was successfully removed in one step using a transparaspinal approach. We discuss technical details of this novel approach along with limitations and possible complications.
