成人会厌及咽部水肿,伴有咽喉炎、呼吸困难,可能是急性咽部感染,也可能是恶性肿瘤浸润所致,对此很难确诊。作者报道一例罕见的弥散性头颈部淋巴管瘤,其表现为急性上呼吸道感染,并对其影象学诊断及淋巴管瘤的治疗方法进行了讨论。 淋巴管瘤是淋巴组织形成的良性团块,以局部淋巴管肥大为特征。可分为三种组织学类型:单纯型,海棉型和囊性肿瘤,三种类型可能同时出现。这种组织学的改变在出生时就占50％～60％,到两周岁时可达80％～90％。淋巴管瘤多散在分布于颈部,无压痛,柔软且边界不清。80％发生在颈后三角。此例为弥散性淋巴管瘤局限于咽、会厌及下颌下区。
Adult epiglottis and pharyngeal edema, associated with pharyngitis, difficulty breathing, may be acute pharyngeal infection, may also be caused by malignant tumor infiltration, which is difficult to diagnose. The authors report a rare case of disseminated head and neck lymphangioma, which manifests as an acute upper respiratory tract infection and discusses its imaging diagnosis and treatment of lymphangiomas. Lymphoma is a benign mass formed by lymphoid tissue characterized by local lymphatic vessel hypertrophy. Can be divided into three histological types: simple type, sponge type and cystic tumors, three types may appear at the same time. This histological change accounts for 50% to 60% at birth and up to 80% to 90% by the age of two. Lymphoma mostly scattered in the neck, no tenderness, soft and unclear boundary. 80% occurred in the posterior triangle. This case of diffuse lymphangioma confined to the pharynx, epiglottis and submandibular area.
