Polyorchidism and rete testis adenoma: ultrasound and MR findings.

Polyorchidism is an uncommon congenital anomaly. It is associated with an increased frequency of testicular malignancy, cryptorchidism, inguinal hernia, and torsion. Sonography may be used to confirm the clinically suspected diagnosis. We present a case of polyorchidism in which a rete testis adenoma was present in one of the testicles. Sonographic and magnetic resonance findings are illustrated.

Retroperitoneal amyloidosis, factor IX and X deficiency,and gastrointestinal bleeding.

A patient with gastrointestinal bleeding due to amyloidosis-related factor X deficiency had extensive calcified retroperitoneal amyloid deposition that was visible on plain radiographs and then localized by computed tomography. The radiologic findings were important in arriving at the proper diagnosis despite negative biopsies.
