The clinical course, computerized tomography (CT) scans, and postmortem reports for 265 patients treated for malignant brain tumors were reviewed. Forty-one patients underwent reoperation for tumor recurrence and one had needle aspiration as a diagnostic procedure; of these patients, seven (3% of 265 and 17% of 42) were diagnosed as harboring tumor cysts and 10 (25% of 41) as having necrotic tumor centers. The CT scans on the 17 patients harboring tumors with surgically confirmed cysts and necrotic centers were reviewed; criteria for distinguishing between cysts and central necrosis are suggested. The relative benefits of repeated aspiration and surgical therapy for these cystic lesions are discussed.
回顾了265例接受恶性脑肿瘤治疗患者的临床病程、计算机断层扫描（CT）结果及尸检报告。41例患者因肿瘤复发接受了再次手术，1例患者接受了针吸活检作为诊断手段；在这些患者中，7例（占265例的3%，占42例的17%）被诊断为存在肿瘤囊肿，10例（占41例的25%）存在肿瘤坏死中心。对17例经手术证实存在囊肿和坏死中心的肿瘤患者的CT扫描结果进行了回顾；提出了区分囊肿和中央坏死的标准。讨论了对这些囊性病变反复抽吸和手术治疗的相对益处。
