Dumbbell neurilemoma simulating lumbar disk disease

The beneficial response to a nonsurgical program for lumbar disk disease in a 56-year-old woman seemed to obviate invasive procedures. Fourteen months later, the previous symptoms and findings recurred. A myelogram showed a block at T12-L1 and a small herniated disk at L4-L5. A neurilemoma was removed. The patient is well 4 years later.
