We aimed to study the relationship between two morphological parameters recently described on MRI images in relation to lumbar spinal stenosis (LSS): the first is the sedimentation sign (SedS) and the second is the morphological grading of lumbar stenosis. ⋯ One-third of surgically treated LSS patients do not present a SedS. This sign appears to be a lesser predictor of treatment modality in our setting of symptomatic LSS patients compared to the severity of stenosis judged by the morphological grade.

To determine the frequency of major complications and identify related risk factors in surgery for hypervascular spinal tumors after preoperative selective arterial embolization. ⋯ Major complications in surgery for hypervascular spinal tumors after embolization are prevalent. Risk factors identified in this study are useful prognostic indicators when considering surgical treatment combined with embolization.

This study aimed to investigate the association between the clinical symptoms of central lumbar spinal stenosis (CLSS) and morphological parameters using magnetic resonance imaging (MRI) data. ⋯ Larger LFA and LFT values are associated with higher ODI values. A larger DSA and SCA are associated with a longer SWD before claudication occurs. To evaluate CLSS patients, clinicians should more carefully inspect the integral morphological parameters than the individual morphological parameters.

Age-related loss of functional muscle mass is associated with reduced functional ability and life expectancy. In disseminated cancer, age-related muscle loss may be exacerbated by cachexia and poor nutritional intake, increasing functional decline, morbidity and accelerate death. Patients with spinal metastases frequently present for decompressive surgery with decision to operate based upon functional assessment. A subjective assessment of physical performance has, however, been shown to be a poor indicator of life expectancy in these patients. We aimed to develop an objective measure based upon lean muscle mass to aid decision making, in these individuals, by investigating the association between muscle mass and 1-year survival. ⋯ Death within 1 year in individuals with spinal metastases is related to lean muscle mass at presentation. Assessment of lean muscle mass may inform decision to operate in patients with spinal metastases.

Spinal intradural extramedullary (IDEM) schwannoma diagnosed by magnetic resonance (MR) imaging is sometimes detected incidentally. Because the natural history of spinal IDEM schwannoma has not been established well, questions remain regarding whether small and asymptomatic tumour has to be removed. We aimed to assess the natural history of spinal schwannoma diagnosed by MR imaging using an accurate and reliable method. ⋯ Spinal probable IDEM schwannoma grew 5.45% of the tumour volume annually and can be divided into growing and stable tumours. The tumour that grows≥2.5% of volume per year needs a careful inspection because it may be not benign schwannoma and keep growing continuously.
