Intrahepatic multicystic biliary hamartoma: A case report.

BACKGROUND: Multicystic biliary hamartoma (MCBH) is a rare hamartomatous nodule of the liver, which has recently been described as a new category of hepatic nodular cystic lesion. Most of them are benign. The imaging findings are similar to those of many other hepatic cystic lesions, but MCBH also has some notable features, such as large cysts, smooth cyst walls, and lack of communication with the hepatic duct. Due to the non-specific radiology, preoperative diagnosis is difficult, and is usually diagnosed by postoperative pathology. Complete resection is the best treatment option, and the postoperative prognosis is good. CASE SUMMARY: When the patients have MCBH, the symptoms may not very typical, and they require a combination of imaging and pathology for diagnosis. Under normal circumstances, the prognosis of MCBH is good. However, in patients with MCBH, more cases need to be observed for verification. CONCLUSION: When the patients have MCBH, the symptoms may not very typical, and they require a combination of imaging and pathology for diagnosis. Under normal circumstances, the prognosis of MCBH is good. However, in patients with MCBH, more cases need to be observed for verification.
