Diagnosis and management of liver masses in pregnancy

Key content Liver masses are increasingly detected in pregnancy because of the widespread use of abdominal ultrasonography. Most lesions are benign and can be treated conservatively, although rarely these can lead to clinical symptoms and the potential for significant haemorrhage. Diagnosis of liver masses is made primarily through radiological assessment with blood tests and rarely by direct liver biopsy. Collaboration between the obstetric department and specialist liver multidisciplinary team is essential to ensure optimal management.Learning objectives Review of liver masses in pregnancy.
