Retrobulbar Metastasis Of Prostate Cancer: A Case Report

Abstract

A case of retrobulbar metastasis of prostate cancer in a 58years old man without lower urinary tract symptoms is reported. He presented with a two months history of protrusion of the right eye, diplopia and pain in the eye. Digital rectal examination revealed a mildly enlarged prostate that was hard in consistency and nodular. Prostate specific antigen estimation showed a value of 32.5ng/ml. a trans-rectal digitally guided biopsy of the prostate confirmed the diagnosis of adenocarcinoma of the prostate. Total androgen blockade was instituted with bilateral orchidectomy and bicalatamide 50mg daily. Response was complete but short-lived for 6months.
Conclusion: We conclude that prostate cancer can present with bizarre symptoms sometimes unrelated to the lower urinary tract. We therefore, advice a thorough physical examination, including a digital rectal examination and prostate specific antigen determination in men above 50years presenting with unexplained symptoms.
