RESUMO
Pachymeningitis is a rare disorder that involves the dura mater of the cranial and spinal nerves. It can lead to localized or diffuse thickening of the dura mater as an inflammatory reaction. Very little is known about this uncommon disease, and even less is known about its exacerbating factors and relationship with chemotherapy. In this report, we present a case of an 86-year-old man with metastatic bladder carcinoma on chemotherapy who experienced worsening pachymeningitis with symptoms such as headache, aphasia, weakness, and seizures. The patient responded well to steroids, and his symptoms improved. This association between exacerbation of pachymeningitis and chemotherapy is rarely encountered, and its mechanism of action is poorly understood. We hope this case report will add to the existing literature on this uncommon phenomenon and its exacerbating factors.
