Ultrasonographic diagnosis and misdiagnosis of hepatic pregnancy / 中国医师杂志

ABSTRACT

Objective:To investigate the ultrasonographic characteristics and misdiagnosis of hepatic pregnancy.Methods:The clinical data and preoperative ultrasound characteristics of 2 cases of hepatic pregnancy admitted to the Affiliated Hospital of Jining Medical College were retrospectively summarized, and related literatures were retrieved from January 1, 1956 to December 31, 2021.Results:A total of 37 cases of hepatic pregnancy were included, among which 35 cases showed liver nodules on ultrasound examination, which were classified into four types pregnancy cystic (24 cases), thick-walled cystic echo (6 cases), heterogeneous hyperecho (3 cases) and mixed cyst solid echo (2 cases), the exact diagnosis coincidence rate of each type was 100%, 4/6, 1/3, 0, respectively. Among the 35 liver nodules, 29(82.8%) cases were diagnosed correctly by ultrasound, 1 case was misdiagnosed as choriocarcinoma liver metastasis, 1 case was misdiagnosed as hepatic hemangioma, and 4 cases were diagnosed as liver nodules without suggestive diagnosis. No liver nodules were found in the other 2 cases, including 1 case misdiagnosed as retroperitoneal hematoma and 1 case misdiagnosed as ruptured ovarian cyst.Conclusions:Ultrasonography of hepatic pregnancy may show pregnancy sac, thick-walled cystic echo, hyperecho and mixed echo in liver. The first type is easy to be diagnosed accurately by ultrasound, while the other types are easy to be misdiagnosed. Combined with clinical conditions and the result of enhanced computed tomography (CT), the correct diagnosis rate of hepatic pregnancy can be improved.
