[Dural metastasis as the first manifestation of prostate cancer]

Metastases of prostate cancer to intracranial meninges are rare and often confused with meningiomas or chronic subdural hematomas. These usually occur in patients with a known cancer diagnosis in advanced stages of the disease, and only in some rare cases do its manifestations precede the detection of the primary tumour. The clinical presentation is unspecific. However, due to the affinity of this tumour for the base of the skull, it must be included in the differential diagnosis of men over 70 years of age with cranial nerve palsy. The treatment of these lesions has not been standardized. Within the therapeutic options we find surgical resection, chemotherapy, radiotherapy or a combination of these measures, and yet survival is poor. We present the case of a 77 year old male patient whose initial symptoms of prostate cancer were caused by a metastatic lesion to the dura, confirmed by histopathology. We also review the epidemiological, clinical and imaging highlights of this condition.
