ObjectiveRarely do spinal hamartomas receive attention in the literature, and the majority of previous studies consist of case reports. The purpose of this report, then, is to provide a more accurate diagnosis and treatment of spinal hamartomas by presenting the clinical and surgical outcomes of 8 cases.MethodsThe researchers conducted a retrospective analysis of the data for eight individuals with spinal hamartomas. The eight patients had undergone both preoperative and postoperative magnetic resonance imaging (MRI) and went through surgery. Radiological and pathological criteria were applied to diagnose the spinal hamartomas. The Modified McCormick classification system was used to evaluate neurological function in these patients.ResultsAmong the eight patients, six were male and two were female, with an average age of 37.4 years. The typical duration of symptoms was 14.5 months. During surgery, all lesions were well-defined and located in the bone marrow. Gross total resection (GTR) was achieved in 6 cases, and the anatomical plane was clearly delineated, and subtotal resection (STR) was achieved in 2 cases. None of the patients took postoperative radiotherapy. 14.5 months was the average follow-up period, during this time, MRI did not observe the recurrence or regeneration of residual tumors. The McCormick grade was improved in seven patients and remained stable in one patient.ConclusionsSpinal hamartomas are benign, but they are clinically progressive lesions. Pathology is the basis of accurate diagnosis, and complete preoperative evaluation is crucial for providing suitable treatment and prognosis.Copyright © 2024. Published by Elsevier Inc.
