Extralobar pulmonary sequestration is located outside the lung parenchyma and is covered by a separated pleural sac, which comprises approximately 25% of all pulmonary sequestration.
This article reported one case of an extralobar pulmonary sequestration originated from the mesoesophagus, which was recognized and excised during a lung resection. Histologic examination revealed an ectopic lung tissue with hyperplasia of bronchioles, which was accord with an extralobar pulmonary sequestration.
CT angiogram, ultrasound and MRI can be used to clarify the diagnosis and detect the abnormal feeding arteries of extralobar pulmonary sequestration. Carefulness should be taken while dissecting and ligating the potential feeding arteries. Endovascular occlusion might be an alternative option to surgery.
肺隔离症位于肺实质外，被分隔的胸膜囊覆盖，约占所有肺隔离症的 25%。
本文报道了一例起源于中食管的肺隔离症，在肺切除术中被发现并切除。组织学检查显示为异位肺组织，细支气管增生，符合肺隔离症。
CT 血管造影、超声和 MRI 可用于明确诊断并检测肺隔离症的异常供血动脉。在解剖和结扎潜在供血动脉时应小心。血管内闭塞可能是手术的替代选择。
