“…To our knowledge, there is only one case report describing the interventional embolization of the feeding artery of ALLs with HCC followed by laparoscopic surgery [32]. Huo et al stated that while FDG PET/CT is effective for identifying numerous liver conditions, its sensitivity in the early detection of hepatocellular carcinoma is suboptimal [33]. Additionally, Arakawa et al observed that serum alphafetoprotein (AFP) levels were higher than 1000 ng/mL in 12 out of 19 cases of ALLs or ectopic liver with HCC (63%).…”

Accessory liver lobe is a rare finding, with the most common cases being accessory liver tissue on the gallbladder wall separate from the orthotopic liver. As the incidence of the ectopic liver is low there are only several case reports in published literature that describe similar presentations. We report a case of intrathoracic liver lobe that was connected to the main liver by a thick pedicle. Due to benign presentation, the patient was discharged without any surgical intervention. This case highlights the importance of understanding anatomical variability of internal organs, understanding the risks of torsion and malignant transformation of the accessory liver tissue. The literature review provides an excellent overview of published case series and reports, and outlines current recommendations on imaging, diagnosis, and management.

“…[3] Few reports demonstrated extrahepatic HCC locate at lateral of left liver lobe. [5,11–14] Part of them laparotomy disclosed no connection between the tumor and the left hepatic lobe. [5,11] Only very few cases confirmed that had a stalk or pedicle between the tumor and the liver.…”

“…There was so little literature aiming at PET/CT finding about ALL with HCC. Huo et al [14] reported although FDG PET/CT is an excellent modality in detecting a variety of hepatic pathologies, the sensitivity in the early detection of hepatocellular carcinoma is suboptimal. In comparison, 11C-acetate PET/CT is more accurate in this clinical setting.…”

Introduction:Accessory liver lobe (ALL) is a rare congenital anomaly. ALL combined with hepatocellular carcinoma (HCC) is even rarer. Most ALLs with HCC are often located in the right liver, and are not supplied by the left hepatic artery.Patient concerns:A 77-year-old man was referred to our hospital because of the level of serum alpha-fetoprotein (AFP) continually increased for 1 month. He had no history of chronic hepatitis, alcohol abuse, or cirrhosis of the liver.Diagnoses:Preoperative computed tomography (CT) scan revealed a 3.0 × 3.0 × 1.0 cm ovaloid-shaped solid mass in the left subphrenic area with isodensity. Magnetic resonance imaging (MRI) showed a mass with a heterogeneous signal on T1- and T2-weighted images. On contrast-enhanced CT and MRI, the mass showed a pattern of early enhancement and washout. Digital subtraction angiography (DSA) confirmed the mass was fed by the branch of left liver artery.Interventions:The mass was treated by transatheter arterial embolization (TAE) followed by surgical resection. Histopathologically showed HCC, consistent with a moderately differentiated.Outcomes:Follow-up of 3 months after surgery, the level of AFP returned to normal gradually.Conclusions:In this report, we describe a rare case of ALL with HCC, located in the left subphrenic area, especially which was supplied by the branch of left hepatic artery has rarely been described. The clinical presentation, radiological features are described in the literature.

“…Riedel's lobe, named after a German surgeon in 1888, is a rare anatomical variation of the liver, often being described as a downward extension of its right lobe [ 1 , 2 ]. It is mostly discovered incidentally when a patient is being investigated for another underlying affliction, and it can remain either a benign discovery or lead to complications, even malignancy [ 3 ]. Since it can be easily overlooked, its prevalence is not clear yet, varying between 3.3% and 31% [ 4 , 5 ].…”

Riedel's lobe is a rare anatomical variant of the liver, more often being diagnosed incidentally, with the patient being investigated for other underlying pathology. As regards acute pancreatitis, this represents one of the most treated diseases worldwide in gastroenterology with a variable severity and outcome. Here, we report a case of a non-palpable Riedel's lobe in a 47-year-old man, smoker, and chronic alcohol consumer, who presented to the hospital with epigastric pain radiating in the right hypochondrium, accompanied by nausea. Based on his clinical examination, laboratory, and imaging findings, he was admitted in the gastroenterology department with the diagnosis of alcohol-related acute pancreatitis. The computed tomography scan emphasized the presence of Riedel's lobe, causing an increased anterior diameter of the liver. Riedel's lobe is, in most cases, an unforeseen radiologic disclosure, which can remain clinically latent, or it can raise confusion regarding the differential diagnosis.
