Posterior epidural intervertebral disc migration and sequestration: A systematic review
Posterior epidural intervertebral disc migration and sequestration (PEIMS) is a rare and debilitating complication of degenerative disc disease. Radiological differential diagnosis is often challenging, complicating the accurate planning of appropriate treatment strategies. We systematically reviewed the literature on PEIMS, focusing on clinical-radiological features and available treatments. PubMed, Scopus, Web of Science, and Cochrane were searched to include studies reporting clinical data of patients with PEIMS. Clinical characteristics, treatment strategies, and functional outcomes were analyzed. We included 82 studies comprising 157 patients. Median age was 54 years (range, 19-91). PE…
Aneurysmal bone cyst of the spine in adult patients: A systematic review and comparison of primary vs secondary lesions.
Background: Spine aneurysmal bone cysts (ABCs) rarely occur in adults. Primary and secondary lesions may show some differences and require appropriate treatments. Objective: To systematically review the literature on adult spine ABCs. Methods: PubMed, EMBASE, Scopus, and Web-of-Science were searched. Clinical-radiological features, treatments, and outcomes were analyzed and compared between primary vs secondary adult spine ABCs. Results: We included 80 studies comprising 220 patients. Primary spine ABCs were more frequent (76.4%). Main symptoms were lower-back-pain (42.8%) and motor deficits (31.2%). Tumors were mostly thoracic (31.4%) or cervical (26.8%), showing lytic (70.4%) and/or cysti…
