Medication-induced changes on magnetic resonance imaging of the brain.

Abstract

In this review the authors focus on abnormal brain magnetic resonance imaging caused by drugs given to patients in any age group for any disease. The review includes viral infections with fever in children/infections in general, epilepsy, psychiatric diseases, multiple sclerosis, neoplasms, bone marrow/organ transplantations, total parenteral nutrition, vaccinations, oral contraceptives and other prothrombotic drugs, and gadolinium deposition. Knowledge of patients' diseases and medications they receive is crucial to establish the correct diagnosis. The absence of these data in a referral for a brain MRI scan can result in completely wrong suspicions and unleash unnecessary, complicated, time-consuming and expensive diagnostics, causing additional stress in patients and their guardians.
