Abstract
Neurological presentation is rare in carcinoma prostate. Brachial plexopathy as the only manifestation of carcinoma prostate is very rare and has not been previously reported. We report an 88-year-old man who presented with new-onset paralysis of the right hand. Digital rectal examination revealed a hard, enlarged prostate and biopsy revealed adenocarcinoma of the prostate with a Gleason score of 7 (4 + 3) with perineural invasion. Computed tomography of the neck showed osteoblastic secondaries involving C6, C7, and T1 vertebrae with a paravertebral soft-tissue mass involving the right foramina of C6, C7, and T1 vertebra. The patient succumbed to the disease despite complete androgen blockade.
