Idiopathic portal hypertension associated with autoimmune thyroiditis.

We report a case of idiopathic portal hypertension (IPH) in association with autoimmune thyroiditis occurring in a 39 year old woman. Ultrasonography revealed a normal liver echotexture. Spleno-portogram confirmed portal hypertension and liver biopsy showed features in keeping with IPH. She was also found to be biochemically hypothyroid with markedly elevated thyroid autoantibodies. These findings may suggest an autoimmune link in the pathogenesis of IPH.
