We report 2 cases of torsion of scrotal malignant tumors of the testis. A review of the literature disclosed several instances of torsion of intra-abdominal testicles with malignant tumors and only 1 case of a scrotal testis. The association of torsion and tumor in these cases may represent 2 manifestations of a dysplastic gonad.

Computed tomography (CT) of hypernephroma is compared with arteriography in terms of accuracy and cost. Computed tomography is shown to be as accurate as arteriography with respect to identification and diagnosis of most renal masses. In selected cases, it has been more accurate than arteriography because of the definition of adjacent retroperitoneum and tumor extent. Most of our patients having CT have required supplemental inferior vena cavography preoperatively, and a few selected cases have required arteriography. Nevertheless, the renal arteriogram can be omitted in most cases because CT is effective in diagnosing and staging hypernephroma, in addition to being noninvasive and more cost-effective.
