Unusual Presentation of Prostate Adenocarcinoma: Collet-Sicard Syndrome with Dysfunctions of Cranial Nerves VII and VIII

Collet-Sicard syndrome is characterized by the unilateral paralysis of cranial nerves IX–XII. The most common cause is an extradural tumor in the posterior fossa. This syndrome may occasionally occur because of distant metastases. Collet-Sicard syndrome which results from metastatic prostate carcinoma is very rare. A review of the English literature showed that this is the second report of metastatic prostate carcinoma with Collet-Sicard syndrome and dysfunctions of cranial nerves VII and VIII. On the other hand, this is the first report of a patient with prostate carcinoma who initially presented with Collet-Sicard syndrome and showed dysfunctions of cranial nerves VII and VIII.
