Non-Parasitic Cysts (Congenital) of the Liver, With a Study of Aberrant Bile Ducts

Mesothelial cyst of the liver in a neonate

“…Mesothelial cysts have been reported to occur at various sites, such as the spleen, adrenal gland, ovary, falciform ligament, vaginal process of the testicle, and mesentery. We treated a mesothelial cyst of hepatic origin, which was very difficult to differentiate from a liver cyst [2][3][4] before surgery. To the best of our knowledge, only four cases of mesenteric cyst of hepatic origin, including our own, have been reported in the literature [5][6][7][8].…”

“…We treated a neonate with a mesothelial cyst of hepatic origin, which was difficult to differentiate from a liver cyst [2][3][4] before surgery. The presentation, diagnosis, and treatment of the mesenteric cyst in this case discussed.…”

Fine Needle Aspiration Diagnosis of Ciliated Hepatic Foregut Cysts

“…17 They are usually located on the anterior surface of the liver, near the suspensory ligament. 6,10 The liver develops embryologically as a diverticulum of the caudal foregut. 9 Ciliated hepatic foregut cysts probably arise from remnants of the embryonic foregut and are similar to bronchial and esophageal cysts.…”

“…9 Ciliated hepatic foregut cysts probably arise from remnants of the embryonic foregut and are similar to bronchial and esophageal cysts. 10,13,16 Hepatic foregut cysts are unilocular, lined with a layer of ciliated columnar cells, and contain mucus or amorphous cellular debris. From a clinical standpoint, the differential diagnosis of a ciliated hepatic foregut cyst would include other unilocular liver cysts: simple hepatic cyst, parasitic (echinococcal) cyst and two rare entities, epidermoid (or endometrial) cysts and carcinoid tumors with cystification.…”

Solitary Nonparasitic Cysts of the Liver

“…Operation.-The patient was transferred to the surgery service and operated on Oct. 8,1925, under ether anesthesia. Dr. Law, on whose surgical service this patient was operated on, permitted one of us (O. H. W.) to remove the cyst and to include the report of the case in this paper.…”
