Description
Mungmee and Punyarat test a simple imaging ratio in this 2026 surgical study of intradural spinal tumors, growths inside the spinal cord's protective sac. They reviewed forty-six adults treated between 2018 and 2024 with hemilaminectomy. That is a bone-sparing operation that opens only one side of the vertebra. For each patient they measured the tumor's occupancy ratio. That is its cross-section against the spinal canal on MRI scans.
The approach worked well overall: surgeons removed tumors completely in 44 of 46 patients, and 80.4 percent improved neurologically by a median follow-up of 27 months, while only two patients worsened. But the fuller the canal, the worse the recovery. In adjusted analysis the occupancy ratio was the sole independent predictor of failing to improve, each unit increase raising the odds of non-improvement by a factor of 1.31 in the model. The authors offer it as an easy preoperative counseling tool needing external validation.
