Arachnoiditis ossificans is an intradural extramedullary lesion resulting from an unusual chronic meningeal inflammatory process and it is thought to be the sequela of end-stage adhesive arachnoiditis secondary to surgery, trauma, arachnoid hemorrhage, meningeal irritation, myelography (particularly oil-based contrast agents), and spinal anesthesia. The spinal arachnoiditis ossificans may be silent or cause a variety of symptoms depending on its location and uncommonly happen to cause spinal cord compression. Very little attention has been paid to the management and outcome of this rare condition in the neurosurgical reem. We report the case of a 45 years old man admitted with L1 - L2 arachnoiditis ossificans revealed by polyradiculopathy on incomplete cauda equina syndrome mimicking spinal canal tumors. The patient underwent surgery and we performed the laminectomy of L1 - L2, total resection of the lesion, followed by a complete remission of the hemiparesis after three months of kinesitherapy nursing.
