Description
Mohammad Hossein Harirchian and colleagues describe, in 2026, a woman with multiple sclerosis whose new symptoms turned out to be a brain lymphoma rather than a relapse. She had received rituximab for years, a drug that removes B cells from the blood, yet the cancer still grew inside the nervous system.
The patient, aged 58, developed headache, vomiting, imbalance, and thinking problems over about a month. Scans looked unlike her earlier multiple sclerosis lesions, and tissue testing confirmed diffuse large B-cell lymphoma. The case warns clinicians to watch for warning signs of a second disease, even when a familiar diagnosis seems to explain new decline.
