【摘要】：目的:分析软组织良、恶性神经鞘肿瘤(NSTs)的CT和MRI特征,提高对该病影像学诊断的准确性。方法:回顾性分析经手术病理证实的77例软组织NSTs的CT、MRI资料与临床资料,其中良性组63例,包括神经鞘瘤41例和神经纤维瘤22例;恶性组即恶性外周神经鞘膜瘤(MPNST)14例。结果:77例软组织NSTs中64例有疼痛和(或)神经症状记录,以MPNST(8/11)多见,良、恶性组间差异有统计学意义(P0.05)。良恶性软组织NSTs在肿瘤大小的10 cm分界、边缘状况、有无囊变坏死、周围水肿征及周围强化征的差异有统计学意义(P0.05)。结论:根据肿瘤大小的10 cm分界、边缘状况、有无囊变坏死、周围水肿征及周围强化征,结合临床有无疼痛和(或)神经症状有助于软组织NSTs良、恶性的鉴别诊断。
[Abstract]:Objective: to analyze the CT and MRI features of benign and malignant neurilematous tumors of soft tissue and to improve the accuracy of imaging diagnosis. Methods: Ct MRI findings and clinical data of 77 cases of soft tissue NSTs proved by operation and pathology were retrospectively analyzed, including 63 cases of benign group, including 41 cases of schwannoma and 22 cases of neurofibroma, and 14 cases of malignant peripheral nerve sheath tumor. Results among 77 cases of soft tissue NSTs, 64 cases had pain and / or neurological symptoms, most of which were found in MPNST8 / 11. The difference between benign and malignant groups was statistically significant (P 0.05). The difference of benign and malignant soft tissue NSTs between the tumor size and the margin, whether there was cystic necrosis, peripheral edema sign and peripheral enhancement sign was statistically significant (P 0.05). Conclusion: according to the 10 cm margin and margin of tumor size, whether there is cystic necrosis, peripheral edema sign and peripheral enhancement sign, combined with clinical symptoms of pain and / or nerve, is helpful to the differential diagnosis of benign and malignant soft tissue NSTs.
