Aggressive fibromatoses are locally invasive, non-metastasising, fibroblastic soft-tissue tumours. On the basis of examinations made in 6 patients with histologically confirmed diagnosis, the reliability of different imaging modalities in preoperative diagnosis and in follow-up is discussed. The inhomogeneous tumour composition was evident in all imaging procedures. Computed tomography offered the highest sensitivity for tumour detection and proved accurate in demonstrating the characteristic radial tumour spreading of mesenteric aggressive fibromatosis; the attenuation values ranged from 18 to 58 HU. in pre-contrast CT scans. In magnetic resonance imaging the tumours mostly produced a low signal in T1- and T2-weighted sequences; the calculated T2-relaxation times ranged from 97 to 186 ms.
侵袭性纤维瘤病是局部侵袭性、不发生转移的成纤维细胞性软组织肿瘤。基于对6例经组织学确诊的患者的检查，讨论了不同成像方式在术前诊断和随访中的可靠性。在所有成像检查中，肿瘤成分不均匀均很明显。计算机断层扫描对肿瘤检测的敏感性最高，并且在显示肠系膜侵袭性纤维瘤病典型的放射状肿瘤扩散方面被证明是准确的；在增强前CT扫描中，衰减值范围为18至58 HU。在磁共振成像中，肿瘤在T1加权和T2加权序列中大多表现为低信号；计算得出的T2弛豫时间范围为97至186 ms。
