Diagnostic Dilemma in a Septuagenarian Patient: Drug-Induced Liver Injury (DILI) or Autoimmune Hepatitis?

Autoimmune hepatitis is an uncommon, long-term condition in which the immune system targets the liver, leading to inflammation. It can affect individuals of any age or background and often presents either without symptoms or with vague complaints such as tiredness, appetite loss, nausea, or weight reduction. While it can emerge at any point in life, it tends to occur more frequently during adolescence and again in later adulthood. This report describes the case of an elderly woman of Indian origin who was found to have elevated liver enzymes with no clear cause. Subsequent evaluations, including liver biopsy, confirmed autoimmune hepatitis. This case highlights the steps taken to reach a diagnosis and the complexities involved in choosing a suitable management plan.
