Segmental infarction of the testis represents a rare entity. To our knowledge 11 cases have been reported in the literature. We report 4 additional cases of segmental testicular infarction masquerading as testis tumors. Inability to distinguish these benign lesions from malignant testis tumors resulted in orchiectomy in all 4 cases.
We report 5 cases of simple cyst of the testis, the largest series to date, and review the literature. Included are 2 autopsy cases, a case of a multilocular simple cyst and 1 case treated nonoperatively. Based on our experience, simple cyst of the testis should be suspected particularly in an enlarged but otherwise palpably normal testis. High resolution real-time scrotal sonography revealing an anechoic mass in the testis with well defined walls, and enhanced posterior through transmission and edge shadowing is diagnostic for a simple cyst. An asymptomatic simple cyst of the testis may be treated with observation alone. The symptomatic simple cyst should be treated ideally with local parenchyma-sparing excision.
Umbilical artery catheterization in the newborn can lead to perforation of the bladder or urachal remnant with extravasation of urine into the peritoneal cavity. We present a case of such an injury that led to uroascites and respiratory distress. This injury usually requires prompt surgical repair for resolution.
