Two cases of rare spinal tumors recently experienced were both misdiagnosed as a lumbar disc herniation. Disc protrusions were not found at operation.
Case 1; A 20-year-old man was admitted to our clinic, whose chief complaint was lumbosciatica with intermittent claudication. A myelogram showed a narrowing below the level of the L4-5 space. The cause of that was an extradural lipoma.
Case 2; A 33-year-old woman complained of coccygalgia and both sciatica. A myelogram showed a complete block at the level of the L2 body. A laminectomy was done from L1 to L5 and then the removal of almost all the intradural tumor was able to be performed under the operation microscope. The pathological diagnosis was ependymoma.
