Ectopic thyroid in duplicated gall bladder: a rare entity. Case report

Abstract

Duplication of the gall bladder is a rare anomaly. Ectopic thyroid in a gall bladder is also exceedingly rare with only four cases of ectopic thyroid tissue in the gall bladder reported in English literature. We report the unique case of ectopic thyroid tissue in a duplicated gall bladder in a 51-year-old female with recurrent right upper quadrant pain. Abdominal sonography revealed a duplicated gall bladder with the cystic-solid mass in the septum separating the two gall bladders while subsequent histopathology from the cholecystectomy specimen confirmed ectopic thyroid tissue within the wall of double gall bladder.

Ectopic thyroid of the pancreas

“…Of the 34 cases, only 6 cases involved whole-body nuclear scintigraphy; in one case, [ 34 ] scintigraphy was performed after FNAC, while in the other cases it was performed postoperatively. [ 21 , 27 , 32 , 35 , 43 ]…”

Ectopic liver and gallbladder in a cloned dog: Possible nonheritable anomaly

“…Abbreviation: C-sec, cesarean section. Important congenital abnormalities of a gallbladder are related to number (agenesis, bilobed or multiseptate gallbladder), shape (Phrygian cap, diverticulum, or hypoplasia), or position (ectopic gallbladder) [5,44]. The four most common ectopic locations are under the left liver lobe, inside the liver, transverse, and retroplaced [18,19,[45][46][47].…”

Ectopic thyroid in the gallbladder accompanied with gallbladder adenoma

“…Here we report a new case of ectopic tissue in the gallbladder wall, and review the literatures on ectopic thyroid Including our case, there were only 5 cases of ectopic thyroid in the gallbladder wall: a case of thyroid tissue in the perimuscular subserosal connective tissue in the neck region of the gallbladder [3] ; a case of the cystic mass filled with colloid like substance in the body and fundus region after excising subserosal layer [6] ; a case of a small tan nodule in the neck of gallbladder around the cystic duct [5] ; a case of thyroid tissue close to the cystic duct in the gallbladder wall and associated with gastric mucosal tissue [9] ; and our case of thyroid tissue in the body of the gallbladder in the subserosal layer. For the other 4 cases: 1 case of thyroid tissue in fibrofatty tissue adjacent to the gallbladder [12] ; 1 case of ectopic thyroid in the septum between the duplicated gallbladder [7] ; 1 case of the nodule on the serosa aspect of the gallbladder [8] ; and 1 case of an ectopic rest adjacent to the gallbladder. [4] The embryological defect that may cause ectopic thyroid in the gallbladder remains to be investigated.…”

“…Ectopic thyroid is most common in the tongue, in the females, especially in the Asian population, and it may occur in any age. [1] A variety of unexpected locations of thyroid tissues have been reported including the gallbladder, [2][3][4][5][6][7][8][9] lung, [10] duodenum, [11] porta hepatis, [12] pancreas, [13] adrenal gland, [14] fallopian tube, [15] and small intestinal mesentery. [16] Here we reported a rare case of thyroid tissue located in the gallbladder wall, accompanied with adenoma and a cyst lined with pseudostratified ciliated columnar epithelium in the neck region of gallbladder neck.…”
