Turner syndrome may be associated with hepatic adenoma

Abstract

Turner syndrome, caused by complete or partial loss of an X chromosome, is marked by a range of clinical manifestations including short stature, cardiovascular and renal disease. Hepatic involvement is an increasingly recognized concern. Steatosis and elevated transaminases are commonly observed in this population, but case reports have also described hepatic adenoma. Hepatic adenomas are rare, occurring in one per million people in the general population. They are typically benign but malignant transformation or rupture can occur. We sought to investigate whether Turner syndrome is associated with hepatic adenoma. Patients with Turner syndrome encountered at a single, academic institution between 2006 and 2020 were identified using ICD‐10 codes and demographic, medication, laboratory, and imaging data were analyzed. Of the 228 patients identified, 46.9% had liver function testing, which were abnormal in 48.6%. Five of 77 patients with hepatic imaging had abnormalities. Three patients (1.3%) had hepatic adenoma, one after presenting in hemorrhagic shock due to rupture. These findings suggest that patients with Turner syndrome may have an increased risk for developing hepatic adenoma. Annual monitoring of liver function tests is already recommended in Turner syndrome. The addition of periodic hepatic imaging may also be beneficial.
