ABSTRACT
A 36 year-old man after tests for assessing male infertility was diagnosed with primary infertility, bilateral cryptorchidism, nonobstructive azoospermia and discontinuous splenogonadal fusion. Carcinoma in situ was found in his left testicle, which was intraabdominal and associated with splenogonadal fusion. To our knowledge, this is the fourth case of splenogonadal fusion associated with testicular cancer reported. One should always bear in mind the possibility of this association for the left cryptorchid testicle.
Um homem de 36 anos, depois de ser submetido a exames para avaliação de infertilidade masculina, foi diagnosticado com infertilidade masculina primária, criptorquidia bilateral, azoospermia não obstrutiva e fusão esplenogonadal descontínua. Carcinoma in situ estava presente no testículo esquerdo, que tinha localização intra-abdominal e estava associado à fusão esplenogonadal. Esse é o quarto caso de fusão esplenogonadal associada a câncer testicular, segundo nossa avaliação. Deve-se sempre ter em mente a possibilidade dessa associação em testículos criptorquídicos à esquerda.

Transverse testicular ectopia (TTE) is a rare congenital anomaly in which both testes migrate toward the same hemiscrotum. In most cases, the correct diagnosis is not made preoperatively, but it's made during an inguinal herniotomy or during surgical exploration for an undescended testis because TTE is clinically misdiagnosed as an symptomatic inguinal hernia or as a tumor of the testis on the side to which the ectopic testis has migrated or as an undescended testis on the contralateral side. US and MR imaging can detect the transverse testicular ectopia by its characteristic appearance and so provide useful information about any associated anomalies. We report here on a case of transverse testicular ectopia that was diagnosed by US and MR imaging in a 10-month-old boy, and we review the relevant literature.

PURPOSE: To find the magnetic resonance (MR) imaging patterns and to determine the viability in normal, infracted and reversible ischemic testis of the rat. MATERIALS AND METHODS: Fifteen Sprague-Dawley rats were examined and they were divided into four groups. Group 1 was the control group, group 2 had a complete testicular artery ligation, group 3 had a complete ligation with reperfusion after 1 hour and group 4 had a complete ligation with reperfusion after 12 hours. All four groups were imaged every 5 minutes for 30 minutes. Delayed MR imaging was obtained every 30 minutes for 90 minutes. Two follow-up MR images were performed in all groups at a one-week interval. The signal intensity was measured in the normal testis, ischemic testis, and in muscle, water and fat in every rat at each time, with the phantom attached near the scrotum during the scanning. The signal intensities were analyzed statistically. RESULTS: On initial and 2-week follow-up examinations, the pattern of change differed among four groups (p<0.001). Group 1 and Group 3 did not show any marked change over time at each examination. Group 3 showed strong enhancement at the first week follow-up. Group 2 showed steadily delayed enhancement at each examination. Group 4 had same pattern with the Group 2 with higher enhancement intensity in parallel. CONCLUSION: MR images with Gd-DTPA could be useful for the diagnosis of damaged testicular tissue and for the determination of testicular viability.

Adenocarcinoma of the rete testis arising in the mediastinum testis is a rare, highly malignant neoplasm. Wedescribe one such case in a 25-year-old male who presented with a palpable right scrotal mass which metasta-sizedto the right inguinal lymph node eight months later. Ultrasonography of this tumor showed a complex cystic andsolid mass in the swollen right scrotum, which was separate from the right testis. Ultrasonographic and clinicalfindings suggested that the mass was, indeed, paratesticular. Surgical pathology following right radicalorchiectomy and hemiscrotectomy, however, confirmed the presence of an exophytic adenocarcinoma of the retetestis. A pelvic CT performed to evaluate a right inguinal mass, which was palpated eight months later, revealed amainly cystic mass in the right inguinal area. Metastasis was confirmed by biopsy.
