[Involvement of cranial pairs as manifestation of prostatic cancer]

Two cases of prostate cancer (PC) which presented clinically with affectation of the cranial pairs due to skull base metastasis. In both cases, existence of intraparenchimatous brain metastasis was excluded. Initial improvement with hormonal therapy was followed by clinical, analytical and radiological relapse due to spread of process until death, at 11 and 36 months from diagnosis. Although PC's bone metastasis are frequent, their location at the skull base is uncommon. Even more rare are the cases which present with changes in the cranial pairs in the absence of signs and symptoms of prostatism.
