Summary
Mesothelial cysts, rare fluid-filled sacs, were found at the porta hepatis, a location previously unreported for these lesions. This incidental finding occurred during a routine surgical procedure.
Area of Science:
- Gastroenterology and Hepatology
- Surgical Pathology
Background:
- Mesothelial cysts are uncommon cystic lesions lined by mesothelial cells.
- These cysts typically occur in the peritoneum, pleura, or pericardium.
- Previous literature has not documented mesothelial cysts at the porta hepatis.
Observation:
- A 45-year-old woman presented for an open cholecystectomy.
- An incidental finding of a cystic lesion was noted at the porta hepatis during surgery.
- The lesion was subsequently identified as a mesothelial cyst.
Findings:
- Histopathological examination confirmed the cystic lesion to be a mesothelial cyst.
- This represents the first reported case of a mesothelial cyst at the porta hepatis.
- The cyst was asymptomatic and detected incidentally.
Implications:
- This case expands the known anatomical distribution of mesothelial cysts.
- It highlights the importance of considering rare diagnoses in surgical pathology.
- Further investigation may be warranted to understand the etiology and potential clinical significance of porta hepatis mesothelial cysts.

01:17Gross Anatomy of the Liver
The liver, the largest gland within the human body, is a firm and reddish-brown organ. This wedge-shaped structure weighs approximately 1.5 kg and occupies a significant portion of the right hypochondriac and epigastric regions. It extends more to the right of the body's midline than to the left.
Located under the diaphragm, the liver is almost entirely ensconced within the rib cage, providing it with substantial protection. Except for the superior most bare area, the liver's surface is covered...

01:17Gallbladder
The gallbladder is a small, pear-shaped organ that plays a crucial role in our digestive system. Measuring about 10 cm in length, it is comparable in size to a kiwi fruit and is located in a hollow area on the lower surface of the liver. The gallbladder's primary function is to store and concentrate bile, a fluid produced by the liver that aids in digestion.
The gallbladder's anatomy consists of three regions: the fundus, body, and neck. Extending from the neck, the cystic duct joins the common...

01:19Appendicitis
Appendicitis is an acute inflammatory condition of the vermiform appendix, most commonly caused by obstruction of its lumen. The appendix is a narrow, blind-ended pouch that extends from the cecum, making it particularly prone to obstruction. Causes include fecaliths, lymphoid hyperplasia (often after viral infections), parasites, tumors, or foreign bodies. This obstruction initiates a cascade of pathological changes.Luminal Obstruction and Early InflammationAfter obstruction, normal mucosal...
01:22Portal Hypertension
Portal hypertension is an increase in blood pressure within the portal venous system. Normally, this pressure is less than 5 mmHg. It is considered clinically significant when it rises above 10 mmHg. At this threshold, complications from altered blood flow and venous congestion emerge.EtiologyPortal hypertension arises from conditions that impede blood flow through the liver. The most common cause is cirrhosis, in which chronic liver injury leads to fibrotic scarring. This fibrosis narrows or...
01:20Cholecystitis
Cholecystitis is inflammation of the gallbladder, most commonly caused by obstruction of the cystic duct. This blockage prevents bile from draining, leading to gallbladder distension, inflammation, and potentially serious complications. This condition may present acutely or chronically and can happen with or without gallstones.EtiologyAbout 95% of cholecystitis cases are calculous, caused by gallstones blocking the cystic duct, leading to bile accumulation and inflammation of the gallbladder...
