Transient left homonymous hemianopsia and encephalopathy following treatment of testicular carcinoma with cisplatinum, vinblastine, and bleomycin.

A 36-year-old man being treated with cisplatinum, vinblastine, and bleomycin for testicular carcinoma developed a dense left homonymous hemianopsia, encephalopathy, and a partial nondominant parietal lobe syndrome. He subsequently had a resolution of all signs and symptoms, suggesting that these alarming events were a toxic but reversible side effect of the chemotherapy.
