目的探讨颅骨韧带样纤维瘤的影像学特点,提高对其诊断正确率。方法回顾性分析经手术病理证实的5例颅骨韧带样纤维瘤患者的影像学表现。结果 5例均为单发病灶,3例发生在顶骨,2例发生在额骨,病灶均呈膨胀性骨质破坏,内见残存骨嵴及钙化灶,骨皮质可中断,无明显软组织肿块,病变在MRI T1WI上呈混杂低信号,在T2WI上呈以高信号为主的混杂信号,增强后呈明显不均匀强化。结论颅骨韧带样纤维瘤多见于顶骨及额骨,以板障内膨胀性骨质破坏伴有粗大结节样钙化为其特征性表现。
Objective To investigate the imaging features of skull ligament-like fibroids and to improve the diagnostic accuracy. Methods The imaging findings of 5 patients with craniofacial-like fibroma confirmed by surgery and pathology were retrospectively analyzed. Results 5 cases were single lesions, 3 cases occurred in the parietal bone, 2 cases occurred in the frontal bone, the lesions showed swollen bone destruction, internal remnants of bone crest and calcification, the cortical can be interrupted, no significant soft tissue mass, Lesions showed mixed low signal on MRI T1WI, mixed signal dominated by high signal on T2WI, and enhanced obviously uneven enhancement. Conclusion Cranial ligament-like fibroids are more common in the parietal and frontal bones. Expanded bone destruction with coarse nodular calcification in the platelet is the characteristic manifestation.
