Atypically located bronchogenic cyst causing invagination

Bronchogenic cysts are formed due to abnormal budding from the bronchial tree and contain cuboidal ciliated epithelium, smooth muscle fibers, submucosal bronchial glands, or cartilage. They are most commonly localized in the lung parenchyma and mediastinum. In the literature, there are reports of very rare atypically located bronchogenic cysts found in the subcutaneous tissue, cervical region, stomach, diaphragm, cardiac septum, retroperitoneum, and abdomen. However, ileal localization of bronchogenic cysts is extremely rare. Although bronchogenic cysts can remain asymptomatic for years, most eventually become symptomatic over time due to compression of surrounding tissues, hemorrhage, or infection. Among the reported symptoms, there has been no documented case of a bronchogenic cyst presenting with intussusception. Herein, we aimed to present a case of atypically located bronchogenic cyst causing ileal intussusception in a 30 month-old male patient. An atypically located bronchoscopic cyst should be considered in cases of intussusception.
