Overview of literature: The presence of increased facet fluid on axial T2-weighted magnetic resonance imaging (MRI) has been proposed as a potential marker for motion segment instability in the lumbar spine. Both facet fluid on MRI and spinal instability on dynamic x-rays are crucial in diagnosing and managing low back pain, guiding decisions on surgical interventions. Methods: We analyzed the prospectively collected data from patients meeting the inclusion criteria. Facet fluid measurements were made according to Schinnerer's criteria on axial T2weighted images and anterior translation as a marker of instability was evaluated on dynamic radiographs for all eligible patients. Statistical analysis was performed using IBM SPSS version 23, employing cross-tabulations, chi-square tests, and Pearson correlation. The study utilized a null hypothesis to evaluate the association between facet fluid and spinal instability. Results: Our findings demonstrated a statistically significant association between positive facet fluid on MRI and the occurrence of instability on lateral flexion/extension radiographs. Moreover, we found a strong positive correlation between the volume of facet fluid on axial MRI and the level of spinal instability on standing flexion/extension radiographs. Based upon these outcomes, we propose that standing lateral flexion-extension radiographs should be routinely administered to patients exhibiting increased facet fluid signals on MRI, as they may provide valuable information regarding potential spinal instability. Further research will help establish the clinical utility of this approach in managing degenerative lumbar diseases.

Case Description: A 25-year-old male presented following a high velocity road traffic accident with back pain and tenderness at the L/S junction. His radiologic images showed bilateral locked facets at the L5/S1 level with Grade 1 spondylolisthesis, bilateral pars fractures, acute traumatic L5/S1 disc herniation, and disruption of the anterior and posterior longitudinal ligaments. After undergoing a L4-S1 laminectomy with pedicle screw fixation, he became asymptomatic and remained neurologically stable. Conclusion: L5/S1 facet dislocation whether unilateral or bilateral needs to be diagnosed early and treated with realignment and instrumented stabilization.

Mostly, they present as intradural extramedullary lesions. They are quite rare in the intramedullary (IM) region. We report a case of IM schwannoma. Case Description: A 52-year-old gentleman presented with a history of gait instability and numbness in bilateral lower limbs. He had clinical signs of myelopathy. His magnetic resonance imaging (MRI) dorsal spine was done that showed an intradural IM lesion at the level of D11, with one differential of ependymoma. Near total resection of lesion was done and histopathology reported it schwannoma. Conclusion: Preoperative radiologic assessment for IM spinal lesions is difficult and high degree of suspicion should be present when approaching a patient with somatic pain and IM lesion on MRI, keeping in mind one differential of IM schwannoma.
