Abstract

Bronchogenic cysts are congenital lesions usually observed in the mediastinum, near the tracheal carina and middle mediastinum. Herein, we present an exceedingly rare case of intradiaphragmatic bronchogenic cyst with an infectious complication in a 52-year-old man. Chest CT and three-dimensional volume rendered reconstructed images revealed an oval, cystic mass with multiple nodular calcifications, centered in the left diaphragm crus. CT facilitated documentation of the healing process of this rare entity, revealing decrease in size and increase in internal density.

Figure

  • Fig. 1 Bronchogenic cyst in an intradiaphragmatic location in a 52-year-old man with dyspnea. A. Chest CT shows an about 10 × 9.8 × 10.8 cm sized, oval mass across the left pleural cavity and left retroperitoneum on the axial and coronal reformatted images (white arrows). It has well defined margins and low attenuation of 18–21 Hounsfield unit, which suggests a cystic lesion. The center of the mass is in the left diaphragmatic crus. Contrast enhanced CT reveals peripheral enhancement and multiple enhancing inner septations (arrowheads, left lower and right lower). In the lower portion of the mass, multiple nodular calcifications are seen (black arrow, right upper). There are also pleural effusion and passive atelectasis. B. On chest CT acquired at another facility approximately 2 years previously, a smooth margined, elliptical and heterogeneous density mass is seen in left diaphragmatic crus (white arrows). Multiple nodular calcifications are seen in the mass (black arrow, right panel).
