The Utility of Delta-9-Tetrahydrocannibinol Therapy in a Multiple Sclerosis Patient with a Neoplastic Brain Lesion

Abstract

Multiple sclerosis (MS) can sometimes cause uncommon pseudotumoural lesions that produce atypical symptoms, such as motor epileptic seizures which are often pharmacoresistant. In these cases, accurate diagnosis is essential for correct therapy, even if unconventional. We present the case of a brain tumour in a 40-year-old relapsing-remitting MS patient who presented with pharmacoresistant seizures which eventually responded to nabiximols. After various therapeutic approaches, delta-9-tetrahydrocannabinol therapy was introduced with good results. Spasticity improved, pain decreased and we observed a reduction in the number of daily seizures. It is possible that delta-9-tetrahydrocannabinol can enhance the efficacy of anti-epilepsy therapy.
