RESUMO
A case of malignant paraganglioma of the prostate, metastatic to the retroperitoneal area, is reported. The literature is reviewed and the possible origin of the disease is discussed. We believe that this is the first report of this entity of prostatic origin.

A hypovascular pheochromocytoma not visualized by nephrotomography or arteriography but demonstrated successfully by computerized axial tomography is described. We propose that this non-invasive test be used alone or in conjunction with other modalities to assist in the localization of this elusive and potentially fatal tumor.

A simple, safe and rapid scanning procedure using 99-m technetium is described for the diagnosis of torsion of testicles. The procedure is especially useful in the adult with an enlarged scrotum of recent origin in whom the surgeon cannot clinically differentiate torsion of the testicle from epididmitis. It is not suggested that this procedure replace immediate scrotal exploration in the acutely illpatient.
