By studying the MRI apperances of postcricoid area invaded by laryngeal carcinoma, to identify the characteristic appearances of the invaded postcricoid area and to provide information on the early detection of the lesions.
Eighteen cases of MRI images of postcricoid area invaded by laryngeal carcinoma were included in this study. To find out the characteristic manifestation of the lesions, the destructions of surrounding structures and layers, and the invaded extent were observed.
In 18 cases the invaded lesions of postcricoid area include the mucous layer, submucous fat layer and the mucous layer of anterior wall. In 14 cases the invaded lesions of postcricoid area include the mucous layer, submucous fat layer and the mucous layer of the posterior wall. The soft tissue mass was found in 15 cases, and disappeared hypopharynx cavity in 16 cases. In 14 cases, the full-thickness of both anterior and posterior walls were invaded, accompanied with soft tissue mass and disappeared hypopharynx cavity.
The postcricoid area invaded by laryngeal carcinoma usually shows the destruction of normal structures, signal change in MRI and soft tissue mass. Being familiar with the imaging of the invaded postcricoid area is extremely important to early detect laryngeal carcinomas invading postcricoid area.
通过研究喉癌侵犯环状软骨后区的MRI表现，识别受侵环状软骨后区的特征性表现，为病变的早期检测提供信息。
本研究纳入18例喉癌侵犯环状软骨后区的MRI图像。为找出病变的特征性表现，观察周围结构和层次的破坏情况以及受侵范围。
18例中，环状软骨后区受侵病变累及黏膜层、黏膜下脂肪层及前壁黏膜层；14例累及黏膜层、黏膜下脂肪层及后壁黏膜层。15例发现软组织肿块，16例下咽腔消失。14例前后壁全层受侵，伴有软组织肿块及下咽腔消失。
喉癌侵犯环状软骨后区通常表现为正常结构破坏、MRI信号改变及软组织肿块。熟悉受侵环状软骨后区的影像学表现对早期检测侵犯环状软骨后区的喉癌极为重要。
