Primary non-Hodgkin's lymphoma (NHL) occurring in the cauda equina region within the spinal canal is exceedingly rare. It is characterized by severe clinical symptoms, a high rate of misdiagnosis, rapid progression, poor prognosis, and significant metastasis potential. In this paper, we report 1 case of a 58-year-old female with primary NHL and another case of a 69-year-old male with secondary NHL. Both cases exhibited similar MRI findings, presenting the ``cauda equina engulfment'' sign. Early diagnosis and treatment, based on the recognition of these rare imaging features in combination with clinical history and cauda equina histopathological examination, are crucial for improving patient outcomes.
原发性非霍奇金淋巴瘤（NHL）发生于椎管内马尾区极为罕见。其特点为临床症状严重、误诊率高、进展迅速、预后差且具有显著转移潜能。本文报告1例58岁原发性NHL女性患者及1例69岁继发性NHL男性患者。两例均表现出相似的MRI表现，呈现“马尾包绕”征。结合临床病史及马尾组织病理学检查，认识这些罕见的影像学特征并进行早期诊断和治疗，对改善患者预后至关重要。
