Abstract

We present a case of an intraperitoneal bronchogenic cyst located at inferior surface of the liver, next to the gallbladder which clinically mimicked a gallbladder tumor. This is the first case reported in Korea, and we offer reviews of the related literatures. A 48-yr-old woman was admitted to our hospital because of intermittent abdominal pain in right upper quadrant. Computed tomography showed a large mass alongside the gallbladder. During laparotomy, the mass showed an ovoid cystic nature, which was attached to the normal gallbladder and liver bed. Cyst excision with cholecystectomy was performed, and histopathological examination revealed a bronchogenic cyst. Most bronchogenic cysts have a benign nature, but malignant changes have also been reported. Therefore, if a cystic tumor in the abdomen is suspected during preoperative diagnosis, a bronchogenic cyst should be considered in the differential diagnosis.

Figure

• 

  Fig. 1 Sonographic finding showing a well-defined round cystic mass adjacent to the gallbladder, the lesion is filled with echogenic materials.

• 

  Fig. 2 Post-contrast sequential axial abdominal CT scan shows a well-defined round cystic mass at the inferomedial aspect of the gallbladder. The internal density of the cystic mass appears as a subtle increase than that of the gallbladder.

• 

  Fig. 3 On operation, the mass is ovoid and cystic and is attached to the normal gallbladder and liver bed.

• 

  Fig. 4 The cut section of the specimen shows a single large cystic cavity, containing a thick brownish mucoid fluid.

• 

  Fig. 5 Cyst lining is composed of respiratory type epithelium, underlying lamina propria, and smooth muscle (A, H&E, ×40). Pseudostratified ciliated columnar epithelial cells are interspersed occasionally with goblet cells (arrow head) (B, H&E, ×200).
