Abstract
Background/Objectives: Turner syndrome (TS) is a genetic chromosomal disorder including various manifestations depending on the karyotype; endocrine, gastrointestinal, respiratory, neurological, urogenital, musculoskeletal, and cardiovascular disorders contribute to increased morbidity and mortality. Liver function abnormalities are less well studied and mostly associated with insulin resistance, obesity, diabetes, hypogonadism, hypothyroidism, and autoimmune conditions. The association of liver pathology with architectural changes in various etiologies and the metabolic dysfunction-associated liver disease is of particular interest. Methods: Herein, we present three cases of adult women with TS and the persistent elevation of liver enzymes due to porto-sinusoidal vascular disorder (PSVD). Results: In one case, the diagnosis of TS followed the liver biopsy results. The absence of cardiometabolic risk factors, low liver stiffness and cardiovascular malformations may predict this histological diagnosis. Conclusions: Liver function impairment in TS may derive from a broad spectrum of liver pathology, including PSVD, and requires careful evaluation to decrease the risk of complications.
