T-cell lymphoma presenting neutrophilic inflammation in the cerebrospinal fluid

Abstract

A 66-year-old woman presented with upper abdominal pain and weakness in the limbs. She had bilateral uveitis and gastric ulcers. A neurological examination revealed tetraparesis and sensory disturbance in the right arm. A cerebrospinal fluid (CSF) examination showed polymorphonuclear pleocytosis with elevated proinflammatory cytokine levels. Magnetic resonance imaging showed brain lesions and a long spinal cord lesion. She was initially diagnosed with neuro-Behçet's disease and was treated with corticosteroids, resulting in no improvement. A gastric mucosa biopsy indicated T-cell lymphoma colocalizing with neutrophils. The cytokine-mediated neutrophilic inflammation probably caused characteristic CSF and histopathological features. It is noteworthy that T-cell lymphoma may present with CSF neutrophilic inflammation.
