Tracheocele or tracheal diverticulum is an uncommon benign entity that can be congenital or acquired. It is usually diagnosed incidentally on cervicothoracic imaging. Our aim is to describe the etiopathogenic, clinical and paraclinical features of the tracheocele as well as its therapeutic modalities.
We report 2 cases of asymptomatic congenital tracheocele occurred in a boy and a woman, incidentally found on cervical CT scan done for accidental ingestion of chicken bone and infected thyroid hematocele respectively. The tracheocele, in our 2 cases, was probably congenital: no risk factors were noted and the opening of the tracheocele was narrow. The tracheocele was located in the right posterolateral tracheal wall in the 2 cases. It communicated with the tracheal lumen in one case. The female patient underwent a right lobectomy and resection of the tracheocele. For the boy, our attitude was conservative. The evolution was uneventful in the 2 cases.
The presence or absence of risk factors, CT scan, bronchoscopy and histologic exam may distinguish between congenital and acquired forms. Asymptomatic patients are managed conservatively. Surgical resection is the treatment of choice for symptomatic patients.
气管膨出或气管憩室是一种罕见的良性病变，可为先天性或后天性。通常在颈胸部影像学检查时偶然发现。我们的目的是描述气管膨出的病因、临床和辅助检查特征及其治疗方式。
我们报告2例无症状先天性气管膨出病例，分别发生在一名男孩和一名女性身上，男孩因意外吞食鸡骨、女性因感染性甲状腺血肿行颈部CT扫描时偶然发现。在我们的2例病例中，气管膨出可能为先天性：未发现危险因素且气管膨出开口狭窄。2例气管膨出均位于气管右后壁。其中1例与气管腔相通。女性患者接受了右肺叶切除术及气管膨出切除术。对于男孩，我们采取保守治疗。2例患者病情进展均平稳。
危险因素的存在与否、CT扫描、支气管镜检查及组织学检查可区分先天性和后天性形式。无症状患者采取保守治疗。有症状患者的治疗选择为手术切除。
