Abstract

This is a rare case of an ectopic gallbladder detected via ultrasound and CT scan in a 14-year-old male, who was seen at the Emergency Department due intermittent right upper abdominal quadrant pain. He underwent laparoscopic cholecystectomy, where an acutely inflamed gallbladder was located antero-superiorly to the liver at the right subdiaphragmatic area and embedded to the abdominal wall. Available literature regarding this entity is very limited. Aberrant locations of the gallbladder are of great clinical significance since the clinical presentation of cholecystitis may be atypical. Misdiagnosis in imaging may affect the course of patient treatment and technical problems during cholecystectomy and other biliary operations may also be encountered.

Case Report

Anomalously located gallbladder is a relatively rare condition, and only 0.1-0.7

Discussion

The gallbladder is normally situated beneath the right lobe of the liver along the plane of the interlobar fissure, straddling the undersurface of segments IVB and V. The neck is found within the porta hepatis and may extend to the caudal border of the liver [6,8].  Most commonly, ectopic gallbladders are found (1) under the left liver lobe in patients with or without situs inversus totals, (2) intrahepatic, (3) transverse, and (4) retro hepatic or retroperitoneal. Isolated cases of ectopic positions of the gallbladder include the falciform ligament, superior to the right lobe of the liver and under the diaphragm, the abdominal wall, behind the pancreas, or may be intra-thoracic [1-4]. In this case, the gallbladder was located suprahepatically, subdiaphragmatic and adherent to the abdominal wall. Very few literatures have been found describing this variant. Furthermore, a structured review of available related literature from 2010-2016 has revealed that there is limited understanding of the etic-pathogenesis of such condition. The most common presenting symptom of cholecystitis is upper abdominal pain, frequently beginning at the epigastrium then localizing at the RUQ. In some cases, peritoneal irritation may cause a dull colicky pain radiating to the right shoulder or scapula. Nausea, vomiting and fever are generally present.9 In this case, the patient presented with constant RUQ pain which was no radiating, pricking in quality and aggravated by movement, not associated with other signs or symptoms. Ectopic positions of the gallbladder alter the clinical presentation of cholecystitis; hence, are of great clinical significance [2]. Aberrant locations of this organ may pose a diagnostic problem as this defect may be considered as a different entity, such as a mass [5]. According to literature available, whenever there is failure to localize the gallbladder in its normal anatomic position on routine imaging, anomalous location of the gallbladder should always be considered. Ultrasonography will help in such cases. Furthermore, angiography may be employed by identifying the cystic artery. Computed Tomography, Magnetic Resonance Imaging, and Endoscopic Retrograde Cholangiopancreatography may also aid in the preoperative. planning of surgery for these patients, but often are often nonspecific. A study conducted on the use of CT scan in detecting gallbladder anomalies indicated that this modality can be helpful in the study of patients with no visualized gallbladders, as in this case [10]. Thus, the radiologist must always inform the clinician about the presence of an ectopic gallbladder [2]. It has been recommended that cholecystectomy should be done for ectopic gall bladder, even in asymptomatic cases [1].

Conclusion

The atypical presentation of cholecystitis due to abnormal gallbladder locations may cause significant dilemma and delay in the diagnosis and management of patients with such condition [7]. Ultrasonography is the primary imaging modality of choice for gallbladder anomalies, with CT and MRI being more helpful in cases where the organ is aberrantly located. A collaborative approach between the clinician and radiologist is of utmost importance to plan appropriate surgical approaches for these patients. A rare case of a 14-year-old male, whose gallbladder was abnormally located, is presented. Laparoscopic cholecystectomy was performed as it has been recommended for ectopic gall bladder, even in asymptomatic cases.
