■鼻窦内翻性乳头状瘤是一种罕见的鼻腔和鼻旁窦(PNS)良性肿瘤。放射学评价是管理的关键。
一名46岁男性主诉右侧鼻塞和偶尔出血4个月。在前鼻镜检查期间,看到一个粉红色的肉质肿块占据了右侧鼻腔。X线和计算机断层扫描(CT)PNS视图显示右鼻腔和上颌窦混浊。鼻子和PNS的MRI显示出一种特殊的回旋条纹/脑型模式。组织病理学报告描述了内翻性乳头状瘤的特征。患者在全身麻醉下接受了内镜下切除肿块。与邻近的正常粘膜组织一起进行肿瘤的手术切除。患者恢复良好,随访复发。
■鼻窦内翻性乳头状瘤常见于男性的第五至第六十年。CT扫描是评估疾病程度的首选方式。MRI在区分肿瘤与其他疾病以及评估软组织延伸方面优于CT。额窦受累是复发的危险因素。治疗倒置乳头状瘤的第一种选择是用邻近的未受累粘膜完全手术切除。
■在活检证实的病例中,CT和MRI等放射学评估在研究典型形态学中起着关键作用,划定扩展名,并检测复发。
UNASSIGNED: Sinonasal inverted papilloma is a rare benign tumor of the nasal cavity and paranasal sinuses (PNS). Radiological evaluation is the key to management.
UNASSIGNED: A 46-year-old male presented with complaints of right nasal congestion and occasional bleeding for 4 months. During anterior rhinoscopy, a pinkish fleshy mass occupying the right nasal cavity was seen. X-ray and computed tomography (CT) PNS view showed opacification in the right nasal cavity and maxillary sinus. An MRI of the nose and PNS revealed a peculiar convoluted striated/cerebriform pattern. Histopathology report described the features of an inverted papilloma. The patient underwent endoscopic removal of the mass under general anesthesia. Surgical resection of the tumor was performed along with adjacent normal mucosal tissues. The patient recovered well and was followed-up for recurrence.
UNASSIGNED: Sinonasal inverted papilloma is commonly found in males in their fifth to sixth decade of life. A CT scan is the initial modality of choice to evaluate the extent of the disease. MRI is superior to CT in distinguishing tumors from other conditions as well as to evaluate soft tissue extensions. Involvement of the frontal sinus is a risk factor for recurrence. The first option for treating an inverted papilloma is complete surgical removal with the adjacent uninvolved mucosa.
UNASSIGNED: In a biopsy-proven
case, radiological assessments like CT and MRI play a pivotal role in studying the typical morphology, delineating the extension, and detecting recurrence.
