Background: Lumbar spinal stenosis often associates with chronic pain described the abnormal narrowing of the lumbar spinal canal, resulting in compression of neural elements within the central spinal canal or the lateral recesses or the root canals or coordinate with each other. The purpose of this study was to describe and compare the plain X-ray and magnetic resonance imaging features of lumbar canal stenosis. Materials and methods: This was a cross-sectional study of 78 patients with an acquired lumbar spinal canal between October 2017 and May 2018. Results: The X-rays confirmed osteophytes in 92.3%, endplate sclerosis in 88.5% and disc space narrowing 62.8%. On MRI, 213 lumbar levels were lumbar spinal canal stenosis, 181 lumbar levels were evaluated for the grade of central spinal canal stenosis. Conclusions: X-ray examination has limitations in a diagnosis of lumbar spinal stenosis but also serves as a diagnostic aid. MRI is well diagnosed as spinal pathology as well as lumbar spinal stenosis. Key words: Lumbar spinal, Lumbar spinal stenosis, Magnetic resonance imaging (MRI), X-ray, Grading

✓ Periosteal chondromas located in the spine are rare. The authors document a case of periosteal chondroma in the lumbar spinal canal of a 77-year-old man. The patient had severe pain in his right leg and used a wheelchair because of weakness in both legs. Magnetic resonance imaging revealed a round tumor that was hypo- or isointense on T1-weighted images and uniformly hyperintense on T2-weighted images. Administration of gadolinium-diethylenetriamine pentaacetic acid resulted in margin enhancement on T1-weighted images. During the operation, a round tumor 1.5 cm in diameter was found on the surface of the anterior wall of the L-3 lamina. Histological examination revealed that the tumor consisted of chondroid tissue with typical chondrocytes, indicating that it was a periosteal chondroma.

Abstract BACKGROUND Congenital spinal stenosis (CSS) of the cervical spine is a risk factor for acute spinal cord injury and development of degenerative cervical myelopathy (DCM). OBJECTIVE To develop magnetic resonance imaging (MRI)-based criteria to diagnose preexisting CSS and evaluate differences between patients with and without CSS. METHODS A secondary analysis of international prospectively collected data between 2005 and 2011 was conducted. We examined the data of 349 surgical DCM patients and 27 controls. Spinal canal and cord anteroposterior diameters were measured at noncompressed sites to calculate spinal cord occupation ratio (SCOR). Torg–Pavlov ratios and spinal canal diameters from radiographs were correlated with SCOR. Clinical and MRI factors were compared between patients with and without CSS. Surgical outcomes were also assessed. RESULTS Calculation of SCOR was feasible in 311/349 patients. Twenty-six patients with CSS were identified (8.4%). Patients with CSS were younger than patients without CSS (P = .03) and had worse baseline severity as measured by the modified Japanese Orthopedic Association score (P = .04), Nurick scale (P = .05), and Neck Disability Index (P < .01). CSS patients more commonly had T2 cord hyperintensity changes (P = .09, ns) and worse SF-36 Physical Component scores (P = .06, ns). SCOR correlated better with Torg–Pavlov ratio and spinal canal diameter at C3 than C5. Patients with SCOR ≥ 65% were also younger but did not differ in baseline severity. CONCLUSION SCOR ≥ 70% is an effective criterion to diagnose CSS. CSS patients develop myelopathy at a younger age and have greater impairment and disability than other patients with DCM. Despite this, CSS patients have comparable duration of symptoms, MRI presentations, and surgical outcomes to DCM patients without CSS.
