[Renal hydatid cyst: preoperative diagnosis and therapeutic implications].

Renal hydatid disease is a rare condition in temperate climates, but must be diagnosed. The authors describe the systematic radiological and serological assessment for a renal cystic mass establishing a preoperative diagnosis. On the basis of this preoperative diagnosis, essential precautions can be taken to avoid the specific complications of this disease and a nephron-sparing procedure can be performed.

[Testicular epidermoid cyst].

Epidermoid cyst of the testis is a rare benign tumour. The diagnosis is strongly suggested by ultrasound and MRI. Conservative surgery is possible in the case of a small isolated lesion and requires intraoperative histological confirmation.

[An MRI study of primary testicular tumors].

Magnetic resonance imaging (MRI) is a high performance tool for morphological assessment and tissue characterization in the presurgical work-up of scrotal tumors. A wait-and-see attitude is now possible for benign lesions identified as epidermoid cysts. Pathology examination remains more pertinent for an exhaustive assessment of local extension, but MRI can provide a convincing, if not definitive, distinction between seminomatous and non-seminomatous germ cell tumors.

[Bladder herniation in a inguinal-scrotal hernia complicated by acute renal insufficiency].

We report one case of massive inguino-scrotal bladder herniation which was responsible for an acute obstructive renal insufficiency. The different types of bladder hernias and their anatomic factors are described. The clinical-radiological findings and surgical management are discussed.

[Bladder hemangioma: a rare cause of hematuria. Apropos of a case. Review of the literature].

The authors report a clinical case of multiple vesical haemangioma, a rare congenital benign vascular tumour essentially affecting children and young adults. These tumours may be solitary or multiple, and essentially spread to the bladder wall. They are sometimes associated with other sites, such as in the rare Klippel-Trenaunay-Weber syndrome.
