We evaluated the clinical and radiological findings in 35 patients with submucosal laryngeal masses. The presenting symptoms were hoarseness, stridor, dysphagia and external neck mass. In 20 cases an important delay between the onset of symptoms and direct laryngoscopy was found. There was a considerable delay between laryngoscopy and definitive diagnosis in 13 cases due to repeated negative biopsies. Computed tomography pointed out the location and extension of the masses in all cases. In 27 mass lesions CT allowed correct prediction of the malignant or benign character of the lesion. In 6 cases no reliable differentiation could be made. The lesion was mischaracterised in 2 cases. Magnetic resonance imaging was also performed in 4 patients, and showed the extent of the lesion better; in 1 case MRI narrowed the differential diagnosis. In the case of a negative biopsy result, radiological findings should incite further investigation, reducing the possible delay between the onset of symptoms and definitive diagnosis.
我们评估了35例喉黏膜下肿物患者的临床及影像学表现。主要症状为声音嘶哑、喘鸣、吞咽困难及颈部肿物。20例患者症状出现与直接喉镜检查之间存在明显延迟。13例患者因多次活检阴性，喉镜检查与明确诊断之间存在相当长的延迟。计算机断层扫描（CT）在所有病例中均指出了肿物的位置及范围。27例肿物病变中，CT能够正确预测病变的良恶性。6例无法做出可靠鉴别。2例病变被误诊。4例患者还进行了磁共振成像（MRI）检查，其对病变范围的显示更佳；1例MRI缩小了鉴别诊断范围。活检结果为阴性时，影像学表现应促使进一步检查，以减少症状出现与明确诊断之间可能的延迟。
