“Splenogonadal fusion”的意思、由来-开放百科全书

The anomaly was first described in 1883 by Bostroem.^[2] Since then more than 150 cases of splenogonadal fusion have been documented.^[3] The condition is considered benign.^[4] A few cases of testicular neoplasm have been reported in association with splenogonadal fusion.^[5]^[6] The reported cases have occurred in patients with a history of cryptorchidism, which is associated with an elevated risk of neoplasm.^[6]

Splenogonadal fusion occurs with a male-to-female ratio of 16:1, and is seen nearly exclusively on the left side.^[3] The condition remains a diagnostic challenge, but preoperative consideration of the diagnosis may help avoid unnecessary orchiectomy. On scrotal ultrasound, ectopic splenic tissue may appear as an encapsulated homogeneous extratesticular mass, isoechoic with the normal testis. Subtle hypoechoic nodules may be present in the mass.^[7] The presence of splenic tissue may be confirmed with a technetium-99m sulfur colloid scan.^[8]
