The Case of a Multi-Locular Bronchogenic Cyst Found in Periadrenal Fatty Tissue

Abstract

Introduction Bronchogenic cysts (BC) are rare congenital cystic lesions formed during the migration of embryonic primitive foregut buds during early embryogenesis (1). They are usually found in the posterior mediastinum, but they may rarely be found in adrenal glands (2). Morphologically, they have the same characteristics as the tracheobronchial system. Most BC are asymptomatic in the early stages, but they can become symptomatic because of pressure caused by the cyst in the surrounding area. Additionally, BC can cause bleeding, rupture or infections (3). Malignant transformation is very rare, with only 0.7% risk (4). A case study, in which a bronchogenic cyst was located in the adrenal area, was presented to us. Bronchogenic cysts are rare congenital cystic lesion formed during the migration of embryonic primitive foregut buds during early embryogenesis. Although they are most commonly located in the mediastinum, in some rare cases, they are found localized in the periadrenal area. In our male patient in 22 year old who had no symptomps, a multiloculated bronchogenic cyst was detected incidentally in the periadrenal area. The lesion was located in the left adrenal area as observed using imaging techniques. The large mass was extracted by laparoscopy to confirm the diagnosis. Histopathological examination described the cyst as multilocular and bronchogenic. The case was presented to us because of the rare occurrence of bronchogenic cysts in the periadrenal area, and an accompanying ectopic kidney condition.
