Both CT and MRI defined the extent of histologically proven recurrent disease, although it was impossible to radiographically distinguish recurrent disease from postoperative scar tissue or mucoperiosteal thickening.
A retrospective analysis of radiographic findings of patients with known inverted papilloma (IP) was performed to identify those characteristics that should prompt preoperative biopsy in patients with polypoid nasal masses.
The radiologic studies from a group of 77 patients with biopsy-proven IP of the nasal cavity or paranasal sinuses were reviewed. Fifty-three computed tomography (CT) scans, 17 cases of plain sinus radiography and 7 cases of magnetic resonance imaging (MRI) were analyzed.
Although no preoperative MRI examinations were available for comparison, CT was the most helpful study for evaluation of primary, nonrecurrent inverted papilloma. CT demonstrated disease-related abnormalities in 90% of studies. The finding of frequent unilateral bony remodeling was demonstrated in 43% of scans. Plain sinus X-rays were abnormal in 70% of cases of primary tumor, with all positive studies showing nonspecific unilateral opacification of the maxillary antrum.
CT和MRI均能明确经组织学证实的复发性疾病的范围，尽管在影像学上无法将复发性疾病与术后瘢痕组织或黏膜骨膜增厚区分开来。
对已知内翻性乳头状瘤（IP）患者的影像学表现进行回顾性分析，以确定那些对于鼻腔息肉样肿物患者应促使其进行术前活检的特征。
回顾了一组77例经活检证实患有鼻腔或鼻窦内翻性乳头状瘤患者的放射学研究。分析了53例计算机断层扫描（CT）、17例鼻窦平片和7例磁共振成像（MRI）。
尽管没有术前MRI检查可供比较，但CT是评估原发性、非复发性内翻性乳头状瘤最有用的检查。在90%的研究中，CT显示出与疾病相关的异常。43%的扫描显示出频繁的单侧骨质重塑。在70%的原发性肿瘤病例中，鼻窦平片显示异常，所有阳性研究均显示上颌窦单侧非特异性混浊。
