RESUMO
Crossed testicular ectopia (CTE) is a rare anomaly, characterized by migration of one testis towards the opposite inguinal canal. Presented here is a case of crossed ectopia of the right testis, treated by extraperitoneal transposition of the gonad and right orchiopexy. Embriology and surgical findings suggest that CTE is a common consequence of many unclear ethiologic factors, specially mechanical ones, and can be associated with Muller duct persistence. Review of literature suggests a classification of CTE into 3 types: I--associated with inguinal hernia alone; II--associated with persistent mullerian remnants; III--associated with other anomalies without mullerian remnants. Treatment includes transeptal orchiopexy or extraperitoneal transposition of the testis, research for mullerian remnants and other anomalies, and long term postoperative follow-up, due to the risk of becoming malignant.

The authors suggest a new methodology for the study of the intrahepatic portal system, using atmospheric air as a contrast medium. They used 48 livers of normal and pathological corpses, obtaining post-mortem cholangiographies and vinyl molds. Comparing the images obtained with literature data and with the vinyl molds, the authors conclude that the method is accurate, presenting furthermore many advantages with regard to contrasts generally used, such as low cost, easy performance, possibility repeating the radiographs as many times as necessary, and the possibility of simultaneous obtaining contrasts of other intra-hepatic systems by use of other radio-opaque contrast media in another system, as for example the biliary or the arterial system.

The authors study 14 cirrhotic livers by means of post-mortem cholangiography and vinyl casts. They analyze the radiographs according to thorough criterions, described in the text, and come to the conclusion that intrahepatic biliary ducts in cirrhotic livers present serious alterations, represented by distorted ducts with focal stenoses, nodular impressions, wall irregularities, increase of the number of obtuse angles and poor peripheral filling, which confer a disharmonic aspect to the intra-hepatic biliary ducts of these organs. Furthermore, they show that livers with post-necrotic cirrhosis present bile ducts much more seriously damaged than those with Laennec's cirrhosis. The paper was submitted to statistical analysis and allows objective conclusions.
