[Retrovesical hydatid cyst. Apropos of 6 cases]. / Le kyste hydatique rétrovésical. A propos de six cas.

The retrovesical hydatid cyst is a very rare site. The authors have observed six cases over a 12-year period. The diagnosis is often delayed. The clinical features are dominated by pain and compression of adjacent organs. Clinical examination sometimes reveals a hypogastric mass. The topographic diagnosis is based on ultrasonography and IVU. Treatment is surgical: retroperitoneal cystopericystectomy. The course is often favourable.

[Granulomatous orchitis. A case report and review of the literature]. / Orchite granulomateuse. A propos d'une observation et revue de la littérature.

Idiopathic granulomatous orchitis is a rare testicle lesion of unknown etiology. We report one case of a specific granulomatous orchitis. Diagnosis and treatment problems are discussed. Clinically, it can be misdiagnosed as a malignant tumour or tuberculosis. The diagnosis is usually made on histological examination after orchiectomy. The aetiology of this disease is still debated. It is supposed to be associated with sperm extravasation causing self-immune reaction.
