Hemorrhagic Hepatic Hemangioma Compressing a Peribiliary Cyst Mimicking an Intraductal Papillary Neoplasm of the Bile Duct: A Case Report
Get PDFHerein, we report a rare, resected case of a hemorrhagic hemangioma originating in contiguity with a peribiliary cyst, which was misdiagnosed as an intraductal papillary neoplasm of the bile duct (IPNB).
A 74-year-old woman was referred to our department for the inspection of a nodular lesion that had emerged within a cystic lesion in the posterior segment of the liver. The cystic lesion had originally been pointed out 7 years before the appearance of the nodule; the nodule increased in size over a short period and was accompanied by contrast enhancement. In addition, a plain CT after an endoscopic retrograde cholangiography (ERC) suggested a communication between the cystic lesion and the bile duct.
As a malignant neoplasm such as IPNB could not be ruled out, surgery was performed. The pathological results revealed that the nodule was a hemorrhagic hemangioma and the cystic lesion was a peribiliary cyst; the hemangioma had compressed the cyst. Several reports of hemorrhagic liver cysts can be found in medical literature, but the coexistence of a hemorrhagic hemangioma and a peribiliary cyst has not been previously reported. A surgical approach is recommended when the possibility of a neoplastic cystic lesion cannot be ruled out by imaging studies.journal articl

Hepatocellular Carcinoma Diagnosed by Routine Abdominal Ultrasound Examination during Pregnancy
Get PDFA case in which HCC was diagnosed by an abdominal ultrasound examination conducted as part of a routine examination during pregnancy, and the patient then underwent cesarean section at 34 weeks' gestation and hepatectomy on the same day is presented.
A 37-year-old woman was found to be hepatitis B surface (HBs) antigen-positive at a routine checkup in the 12th week of pregnancy. She was diagnosed as an inactive hepatitis B virus (HBV) carrier and underwent abdominal ultrasound examination, which found no liver tumor. However, further abdominal ultrasound at 30 weeks' gestation showed an irregular tumor in the right lobe of the liver. Based on the ultrasound findings, the tumor was diagnosed as HCC. There was no evidence of metastases. A cesarean section followed by S5 partial hepatectomy was performed at 34 weeks 3 days of gestation. Ultrasound screening for HCC of pregnant women who are HBV carriers is very important for both mother and child.journal articl
