Five cases of rare gliosarcoma are described with pathologic correlation. Because of its sarcomatous component, gliosarcoma tends to present as a sharply defined, round or lobulated, hyperdense solid mass with relatively homogeneous contrast enhancement and peritumoral edema. Sharp demarcation of the tumor from surrounding tissue may lead to complete removal and prolonged survival despite high malignancy. However, aggressive tumor regrowth occurs often after incomplete resection. The genesis of gliosarcoma is also discussed.
本文描述了5例罕见的胶质肉瘤，并进行了病理对照。由于其肉瘤成分，胶质肉瘤往往表现为边界清晰、圆形或分叶状的高密度实性肿块，对比增强相对均匀，且有瘤周水肿。尽管恶性程度高，但肿瘤与周围组织的清晰分界可能导致完全切除并延长生存期。然而，不完全切除后肿瘤常出现侵袭性复发。本文还讨论了胶质肉瘤的起源。
