Accessory liver lobe attached to the gallbladder wall preoperatively detected by ultrasonography: A case report

View Article: PubMed Central - PubMed

ABSTRACT

An accessory liver lobe is a rare anomaly of the liver.

An accessory liver lobe is usually asymptomatic and incidentally detected during surgery or autopsy in most cases.

An accessory liver lobe should be resected in order to prevent complications and malignant transformation.

Ultrasonography is useful in case of accessory liver lobe for preoperative diagnosis.

Mentions: A 59-year-old female with right upper abdominal pain was admitted to our hospital. She had no relevant past medical or surgical history. Her abdomen was soft with no palpable masses. Abdominal ultrasonography revealed a high echoic area which appeared to be debris in the gallbladder and a 15-mm ellipse-shaped section of liver tissue in front of the gallbladder (Fig. 1). The laboratory data showed slight hepatic dysfunction, with an aspartate transaminase (AST) level of 47 U/L (0–40) and an alanine transaminase (ALT) level of 57 U/L (0–41). An enhanced abdominal computed tomography (CT) scan also showed the accessory liver lobe at the surface of the gallbladder (Fig. 2). Magnetic resonance imaging (MRI) also revealed the accessory lobe at the surface of the gallbladder (Fig. 3). She underwent laparoscopic cholecystectomy for gallstones. During the laparoscopy, an accessory liver lobe, 15 mm in size, was noted on the serosal surface of the gallbladder body with a connection to the main liver sections (Fig. 4). The pedicle was clipped, and this accessory liver lobe was removed together with the gallbladder. The histopathological evaluation of the specimen revealed the diagnosis of an accessory liver lobe due to the presence of normal liver structures without any malignant transformation (Fig. 5). The patient was discharged on the fourth postoperative day without any complications.
