RESUMO
OBJECTIVES: To describe the imaging findings in a series of patients with mesothelioma of the tunica vaginalis testis. METHODS: We reviewed clinical data, imaging findings and follow-up information in a series of 10 pathology-proven cases of mesothelioma (all had US; 2 had MR) of the tunica vaginalis. RESULTS: A variety of patterns could be observed, the most common (5/10) being a hydrocele with parietal, solid and hypervascular vegetations; one patient had a septated hydrocele with hypervascular walls; one had multiple, solid nodules surrounded by a small, physiological quantity of fluid; one a cystic lesion with thick walls and vegetations compressing the testis; two had a solid paratesticular mass. MR showed multiple small nodules on the surface of the tunica vaginalis in one case and diffuse thickening and vegetations in the other one; lesions had low signal intensity on T2-w images and were hypervascular after contrast injection. CONCLUSIONS: A preoperative diagnosis of mesotheliomas presenting as solid paratesticular masses seems very difficult with imaging. On the contrary, the diagnosis must be considered in patients in whom a hydrocele with parietal vegetations is detected, especially if these show high vascularity. KEY POINTS: Mesotheliomas of the tunica vaginalis are rare, often challenging to diagnose preoperatively. Most common finding is a complex hydrocele with hypervascular parietal vegetations. Septated hydrocele, nodules without hydrocele, a thick-walled paratesticular cyst are less common. Preoperative diagnosis may allow aggressive surgical approach and, possibly, a better prognosis.

In this review, we illustrate the spectrum of imaging features after plastic surgical procedures including transverse rectus abdominis myocutaneous flap, deep inferior epigastric perforators flap, latissimus dorsi flap, liposuction, abdominoplasty, and buttocks augmentation. Examples of complications, including seromas, abscesses, fat necrosis, abdominal hernia, and flap necrosis, will also be discussed.

Epidermoid cyst of the testis is a rare benign testicular tumor with varied sonographic appearances. We present a case in which two specific ultrasonographic patterns were seen: (1) an "onion ring" configuration of alternating hyperechoic and hypoechoic regions, described previously as being characteristic of this lesion, and (2) a heterogeneous region with multiple punctate hyperechoic foci.
