Space-occupying tumor bed cysts may exceptionally happen after the resection of diffuse low-grade glioma. Their mechanism and management remain debated. The authors report two cases of tumor bed cysts occurring after the resection of a left temporal diffuse low-grade glioma with two different evolutions.
The first patient showed a spontaneous decrease in the cyst volume and did not report any symptoms. In contrast, the second patient showed a progressive increase in the cyst volume and reported headaches and difficulties in finding words. Endoscopic cyst fenestration was performed and led to symptom relief and normalization of the surgical cavity.
A tumor bed cyst is a rare complication of temporal low-grade glioma resection. Its formation is due to entrapment of the choroid plexus in the temporal horn widely opened into the surgical cavity. Endoscopic cyst fenestration should be offered only in symptomatic cases. https://thejns.org/doi/10.3171/CASE23674.
弥漫性低级别胶质瘤切除术后可能会罕见地出现占位性肿瘤床囊肿。其发生机制及处理方法仍存在争议。作者报告了两例左颞叶弥漫性低级别胶质瘤切除术后出现的肿瘤床囊肿，且囊肿有两种不同的演变过程。
首例患者囊肿体积自发减小，且未出现任何症状。相比之下，第二例患者囊肿体积逐渐增大，并出现头痛及找词困难的症状。遂进行了内镜下囊肿开窗术，术后症状缓解，术腔恢复正常。
肿瘤床囊肿是颞叶低级别胶质瘤切除术的一种罕见并发症。其形成是由于脉络丛被困于广泛开放至术腔的颞角内。仅在出现症状的情况下才应进行内镜下囊肿开窗术。https://thejns.org/doi/10.3171/CASE23674 。
