MRI Findings of Non-Degenerative Pathoanatomical Changes in Low Back Pain

Abstract

Non-degenerative pathoanatomical changes are far less common than degenerative changes but benefi ts most from imaging assessment. This study aimed to evaluate the non-degenerative pathoanatomical changes in patients undergoing MRI for low back pain.The study was a retrospective study conducted for the duration of 3 years in a multimodality-imaging center. All patients undergoing MRI of lumbosacral spine with complains of low back pain with or without radiculopathy were assessed for morphological changes and other abnormal fi ndings. After excluding patients with degenerative changes, non-degenerative pathologies were evaluated. Data was entered in predesigned proforma and analysis was done with SPSS 21.0.There were 183 patients who met the inclusion criteria and were included in the study. The mean age of the patients was 51.23 ±16.86 years. Compression fracture of the vertebra was the most common non-degenerative changes accounting for 34% cases followed by spinal meningeal cysts (26%) and infection (14%). Fractures were more common in upper lumbar level as compared to lower lumbar levels. Meningeal cysts were noted to involve the sacral spinal canal more frequently followed by lower lumbar levels. Infective lesions were equally distributed throughout the lumbar spine. Hemangioma was common lesion involving 16% of cases. Lumbosacral transitional vertebra was seen in 7(3.8%) patients.The common non-degenerative pathoanatomical changes associated with low back pain were traumatic lesion, infection, neoplastic lesion and lumbosacral transitional vertebra.Nepal Journal of Neuroscience 12:59-62, 2015

A hospital based plain radiographic observational study of lumbosacral transitional vertebrae in the Nepalese population

“…However this gender variation in prevalence of LSTV was statistically insignificant. In another MRI based study from Nepal by Karki et al 25 LSTV was seen in 3.8% of patient, which was much lower than that noted in this study. Similarly LSTV prevalence of 10.0% was reported in north Indian population by Garg 24 from evaluation of lumbosacral, KUB and abdomen radiographs.…”

Lumbosacral Transitional Vertebra among Patients Visiting the Department of Orthopaedics in a Tertiary Care Centre: A Descriptive Cross-sectional Study

“…The prevalence rate reported in our study was 9.48%, which was lower compared to similar studies conducted in Nepal. 1,6 However, in an MRI-based study, 7 the LSTV prevalence was 3.8%, much lower as compared to our study. Similarly, other similar studies from India and Saudi Arabia had lower prevalence as compared to this study.…”
