Intrahepatic gallbladder mimicking a cystic liver lesion: A case report & literature review

A comprehensive exploration of gallbladder health: from common to rare imaging findings

This comprehensive review explores a wide range of imaging findings associated with the gallbladder (GB), from anatomic variants to rare diseases. Through an in-depth review of diagnostic modalities including ultrasound, magnetic resonance cholangiopancreatography, CT, and MRI, we aim to highlight the crucial role of imaging techniques in diagnosing GB disorders, as congenital anomalies, inflammatory diseases, neoplasms, and surgical complications. Employing a detailed analysis and comparison of imaging findings across various modalities, this review seeks to improve diagnostic accuracy for GB-related pathologies, facilitating optimal patient management.

Anatomic and Histologic Examination of a Grossly Enlarged Gallbladder Fused to the Inferior Surface of the Liver

The liver is an important organ located on the right side of the abdomen, predominantly responsible for controlling mechanisms related to metabolism, immunity, digestion, detoxification, and coagulation. The gallbladder is an organ present in the gallbladder fossa on the inferior surface of the liver. The main function of the gallbladder is to store and concentrate bile, aiding in fat digestion. In this article, we present a case report of an anomalous gallbladder discovered during cadaveric dissection. The gallbladder appeared to be fused to the inferior surface of the liver and was grossly enlarged. Furthermore, four diaphragmatic grooves were present on the superior surface of the liver. Histologic investigation revealed an acutely inflamed gallbladder wall at the point of fusion, and luminal contents composed mainly of fibrin and degraded blood products. This anatomy could potentially have clinical implications, such as in symptoms of acute and chronic inflammation and right upper quadrant pain. Furthermore, this article adds to the literature a representation of the gallbladder and would be useful in medical education.

Ectopic lesions in the abdomen and pelvis: a multimodality pictorial review

Various ectopic lesions occur in the abdomen and pelvis and affect multiple organs including liver, gallbladder, pancreas, spleen, and organs of the genitourinary system. Ectopic organs may be present outside their normal positions, or ectopic tissues may develop while the original organ exists in its normal position. Both benign and malignant lesions can occur in ectopic organs and tissues. Owing to their unusual location, they can often be misdiagnosed as other lesions or even malignant lesions, such as metastasis or seeding. This multimodality pictorial review provides various cases of ectopic lesions in the abdomen and pelvis, which will help narrow the differential diagnosis and guide clinical decision-making.
