Abstract

BACKGROUND

Primary pathological laryngeal lesions occur rarely in infraglottic space. Modern possibilities of diagnostic imaging of infraglottic space include computed tomography (CT) and magnetic resonance (MR). Diagnostic imaging was performed in potential lesions in this area: inflammatory process - cicatrical pemphigoid, benign neoplastic process - chondroma, malignant neoplastic - squamous cell carcinoma. The aim of the paper is to present clinical and radiographical characteristics of selected lesions located in infraglottic space in MRI examination.

MATERIAL/METHODS: Three patients examined at the Department of Radiology and Diagnostic Imaging of University Hospital No. 1 in Lodz (SPZOZ USK nr 1) from 2010-2011 with a pathological mass in infraglottic space. Standard imaging protocol for MRI of the neck was used in all patients: field of 1.5 T, slice thickness 3 mm, the distance between the scans 10-20%, FOV - 3 mm, sequences: T1 (TR/TE 455/9, 7 ms, T2 (TR/TE 5300/67 ms), T1 + Gd-DTPA (contrast agent Gd-DTPA at 0.2 mmol/kg).

CONCLUSIONS

  1. It is possible to determine characteristic signal pattern for rare lesions of the infraglottic space in MRI. 2. MRI is a valuable complementary modality for the diagnostics and differentiation of lesions in infraglottic space, the evaluation of their advancement and treatment planning.
摘要

背景

原发性喉部病理病变在声门下区很少见。声门下区的现代诊断成像方法包括计算机断层扫描（CT）和磁共振成像（MR）。对该区域的潜在病变进行了诊断成像：炎症性病变——瘢痕性类天疱疮，良性肿瘤性病变——软骨瘤，恶性肿瘤性病变——鳞状细胞癌。本文的目的是展示MRI检查中位于声门下区的特定病变的临床和影像学特征。

材料/方法：2010年至2011年期间，在罗兹第一大学医院放射学和诊断成像科（罗兹第一大学医院编号1）对3例声门下区有病理肿块的患者进行了检查。所有患者均采用颈部MRI的标准成像方案：1.5T磁场，层厚3mm，扫描间距10 - 20%，视野 - 3mm，序列：T1（TR/TE 455/9, 7ms），T2（TR/TE 5300/67ms），T1 + Gd - DTPA（造影剂Gd - DTPA剂量为0.2mmol/kg）。

结论

  1. 在MRI中可以确定声门下区罕见病变的特征性信号模式。2. MRI是声门下区病变诊断、鉴别、评估病变进展及治疗规划的有价值的辅助手段。
