Lipoma-Like Bronchogenic Cyst in the Right Chest Sidewall: A Case Report and Literature Review

Abstract

Bronchogenic cyst most commonly occurs in the mediastinum, followed by the lung. We admitted a 59-year female patient with bronchogenic cyst being uniquely located on the right chest wall of the parietal pleura. Preoperative CT scan showed a local low-density lesion on the right chest wall. The lesion was removed by the thoracoscopic surgery. During the surgical resection, the lesion was observed to be located on the right chest wall. The lesion was surrounded by adipose tissue and covered with entire parietal pleura, which looks like lipoma. Pathological examination demonstrated that the lesion was bronchogenic cyst. In addition, previously reported cases of bronchogenic cyst were reviewed, and the relevant clinical knowledge was discussed.

Intramedullary bronchogenic cyst in the foramen magnum region accompanied with syringomyelia

“…The typical pathological features of spinal bronchogenic cysts are pseudostratified ciliated columnar epithelium in the inner wall of the cysts, and in some cases cartilage and smooth muscle can be visible. [26] The reported cases as well as our present case all harbored these characteristics. Immunohistochemical staining can facilitate the diagnosis, which was positive to epithelial membrane antigen (EMA) but negative for glial fibrillary acidic protein (GFAP).…”

“…[29] Che et al also proposed that mediastinal bronchogenic cysts might have a risk of malignant transformation or spontaneous infection. [26] Chen et al reported spinal bronchogenic cysts might be associated with staphylococcus aureus infection or spontaneous hemorrhage. [2] In the current case and literature review, 9 (45%) cases received gross total resection and 11 (55%) cases received subtotal resection, and no recurrence was noted during the observation period.…”

Hydropneumothorax: A Presentation of Infected Bronchogenic Cyst

“…In a typical noninfected cyst containing serous fluid, T1-weighted images show a low signal and T2-weighted images show a high signal, whereas cysts with increased protein content, hemorrhage, or mucosal components tend to show moderate to high T1-weighted signals on MRI. In cases where CT suggests a solid tumor, MRI becomes an essential diagnostic tool to make an almost precise preoperative diagnosis and differentiate between solid tumors and cysts by T1-weighted image signal showing moderate to high strength and T2-weighted image showing high signal strength [ 17 , 18 ]. Despite the value of various noninvasive diagnostic studies, a definitive diagnosis can only be made by surgical excision and tissue biopsy [ 9 ].…”

Subcutaneous bronchogenic cyst of the chest wall: A case report with brief literature review

“…The differential diagnosis for bronchogenic cysts is established by their location in the body. A cystic neck mass might be an abscess, a thyroglossal duct cyst, or a bronchogenic cyst [25] . A cystic chest wall mass can be diagnosed as a dermoid cyst or teratoma, and a mediastinal cyst can be TB, foregut cyst, pericardial cyst, congenital cystic adenoid malformation, pulmonary sequestration, large B cell lymphoma, or enterogenic cyst [6] .…”
