Lumbar disc herniation occurs with the emergence of the nucleus pulposus from weakened annulus fibrosus fibers. Lumbar disc herniation can be seen as protruding, extruded and sequestered type. Sequestered parts often replace to superior, inferior and laterally. Migration of disc fragment to the posterior epidural space is extremely rare. Here, two cases with posterior epidural migration were reported. One patient had radicular symptom and other one had cauda equina syndrome. In the lumbar magnetic resonance imaging of the patients, there was a mass at the posterior epidural space, compressing the dural sac. The patients underwent emergency operation and the lesions at the epidural space were proved to be sequestered disc fragments which migrated to posterior epidural space. Clinical symptoms of the patients were improved after surgery and the patients were discharged with full recovery.
The Prevalence of Lumbar Paraspinal Muscle Fatty Degeneration in Patients with Modic Type I and I/II end Plate Changes
(2020) Atci, Ibrahim Burak; Yilmaz, Hakan; Samanci, Mustafa Yavuz; Atci, Aysel Gurcan; Karagoz, Yesim; 0000-0001-8952-6866; 31679330; I-1408-2016
Study Design: Retrospective case control. Purpose; The authors of this study assessed whether the prevalence of paraspinal fatty degeneration in correlates with the presence of Methods type I and I/II change in patients with low back pain (LBP) Objective of Literature: Modic changes are bone marrow and end plate changes visible on magnetic resonance imaging. Methods: A consecutive series of 141 patients who attended the neurosurgery outpatient clinic between April 2017 and September 2017 for nonspecific LBP were evaluated. Sixty-one patients with single-level Modic type I or I/II change constituted the patient group. Eighty age-, gender-, and body mass index IIBMIi-matched patients without any Modic changes were recruited as the control group. A retrospective review was performed in 61 patients with Modic changes and 80 controls without Modic changes. The percentage of fatty muscle degeneration was graded by two reviewers using T2-weighted axial images at the L4-L5 level. The system was graded as follows: grade 0, normal; grade I, minimal focal or linear fat deposition; grade H, up to 25%; grade HI, 25%-50%; and grade IV, more than 50%. Results: Sixty-one patients with nonspecific LBP and Modic type I or I/II change and 80 patients without Modic changes were evaluated. There was no difference between these groups in terms of age, gender, and BMI distribution. The mean muscle cross-sectional area in the patient and control groups were 1,507.37 +/- 410.63 and 1,581.64 +/- 379.59. Regarding fatty degeneration, a chi-square test of homogeneity was run, and the two multinomial probability distributions were not equal within the population analyzed. Conclusions: The novel finding of this investigation is that patients with Modic type I and I/II changes have greater amounts of fatty degeneration in their lumbar paraspinal musculature.
