A 46-year-old woman patient presented with a lump right hypochondrium with a diagnosis of calculus cholecystitis on ultrasound abdomen. During laparoscopy, a Riedel’s lobe of liver was seen (Fig. 1). Riedel lobe is a tongue-like, inferior projection of the right lobe of the liver beyond the level of the most inferior costal cartilage, and it is an anatomical variant. It was reported in 1888 by a German Surgeon named Bernhard Moritz Carl Ludwig Riedel in seven lady patients who had palpable masses, and they were all confirmed by open surgical exploration. It is also referred as floating lobe, “tongue like”, or constriction lobe. The incidence of Riedel’s lobe of liver was 3.3 to 31% and more common in females. The potential complications of Riedel’s lobe are rare and include torsion, mass effect morbidity and occasionally laparoscopic-associated difficulty in getting a proper Calot’s triangle view during different surgical procedures [1]. Asymptomatic or uncomplicated Riedel’s lobe usually does not need any special treatment. The only other reason for close follow-up of such cases is due to development of malignancy arising in Riedel’s lobe, for example, hepatocellular carcinoma or metastatic lesion [2].
