MRI增强检查诊断多形性黄色星形细胞瘤的临床案例分析

Diagnosis of Pleomorphic Xanthoastrocytoma with Enhanced MRI Examination: A Clinical Case Analysis

  • 摘要: 多形性黄色星形细胞瘤(PXA)是一种原发性中枢神经系统肿瘤,其临床表现主要为癫痫发作。由于该肿瘤临床表现、影像学表现与颅内其他肿瘤存在重叠,且临床罕见,容易被误诊。本文报道1例PXA病例,16岁男性,突发癫痫一次。头颅MRI检查发现左侧颞叶囊实性占位,考虑胶质瘤可能。随后行肿瘤全切除,病理诊断为PXA(WHO 2级)。患者经治疗后,无癫痫发作,在近1年的随访中,头颅MRI提示未见肿瘤复发。本文对该病影像学特点进行总结,以提高临床医生对本病的认识,为PXA的准确诊断提供思路。

     

    Abstract: Pleomorphic xanthoastrocytoma (PXA) is a primary central nervous system tumor characterized primarily by epileptic seizures as its clinical manifestation. Due to overlapping clinical and radiological findings with other intracranial tumors, and its rarity in clinical settings, PXA is easily misdiagnosed. Here, we report a case of PXA in a 16-year-old male who experienced a sudden epileptic seizure. Cranial magnetic resonance imaging (MRI) showed a cystic-solid lesion in the left temporal lobe, which was interpreted as a possible glioma. The patient underwent a gross total resection of the tumor, and the pathological examination confirmed the diagnosis of PXA (World Health Organization grade 2). After the previous treatment, the patient did not experience any epileptic seizures. During a follow-up period of approximately 1 year, a cranial MRI indicated no signs of tumor recurrence. In this report, a comprehensive literature review based on the imaging findings in this case was conducted to summarize the imaging features of PXA, aiming to enhance the clinicians’ understanding and provide guidance for accurate diagnosis.
