“…Pathological findings previously demonstrated that ALL contains three major structures: a portal vein, hepatic artery, and bile ducts [ 8 , 9 ]. Vessels and bile ducts in ALL (particularly pedunculated lobes) may be connected to the main liver.…”

Background Laparoscopic cholecystectomy (LC) is one of the most commonly undertaken procedures worldwide for cholecystolithiasis and cholecystitis. Accessory liver lobe (ALL) is a developmental anomaly defined as an excessive liver lobe composed of a normal liver parenchyma. Some ALL exist on the serosal side of the gallbladder. We herein present two cases of ALL incidentally detected during LC. Case presentation The first case was a 69-year-old woman diagnosed with chronic cholecystitis. LC was performed. ALL was observed anterior to the wall of the gallbladder and resected after clipping. Pathological findings revealed liver tissue with Glisson’s capsule and a lobular structure in ALL. However, communication between the bile ducts of ALL and the main liver was unclear due to surgical heat degeneration. The second case was a 56-year-old woman diagnosed with acute cholecystitis. LC was performed approximately one month after the attack, and ALL attached to the wall of gallbladder. ALL was clipped and completely resected. Pathological findings showed that the bile ducts of ALL might be connected within the wall of gallbladder. Conclusions We presented two cases of ALL attached to the gallbladder encountered during LC. Since ALL contains a normal liver parenchyma, postoperative bleeding or bile leakage may occur if it is inefficiently resected. Therefore, the complete resection of ALL is important to prevent these postoperative complications.

“…Ultrasonography, plain CT scan, and MRI have also been reported to be non-specific for diagnostic imaging findings in pediatric AHL patients ( 5 ). Hepatic infarcts often showed as hypoechoic, non-vascular areas on ultrasonography ( 15 ). The typical AHL demonstrated on CT is a mass with a narrow base or broad bottom attached to the healthy liver, with the Hounsfield unit consistent with healthy liver tissue ( 16 ).…”

The accessory hepatic lobe (AHL) is a rare congenital malformation of the hepatic tissue, among which the giant AHL is the rarest in children. Patients without complications are usually asymptomatic, and most auxiliary examinations cannot provide a definitive preoperative diagnosis. Surgical procedure is the only recommended management for patients who suffered from the complications of AHL. We report the case of a rare pediatric giant AHL torsion combined with left hepatic vein branch thrombosis which was successfully treated by laparoscopic lobectomy followed by excision of AHL.

“…As the previously vascularized lobe infarcts, some of its imaging characteristics lose their similarity to the normal appearing adjacent liver. The ultrasound findings of a liver infarct are represented as hypoechoic, nonvascular regions on conventional and Doppler sonography [11] . Similarly, the “mass” seen in our patient was originally described as a heterogeneously hypoechoic (relative to normal liver parenchyma) and echogenic masslike structure without flow on color Doppler which lead to the initial diagnosis of a hematoma.…”

An accessory liver lobe is a congenital anomaly of hepatic tissue most commonly due to embryonic heteroplasia. Rarely, accessory liver lobes can undergo torsion and present as an acute surgical emergency. Although common in certain animals, there are only a few reported cases of accessory lobe torsion in humans. We report a multi-modality radiographic diagnosis of an acute torsion and subsequent infarct of an accessory liver lobe following minor trauma in a 29-year old male patient.
