[Mucocele of the appendix. Retrospective study of 10 cases].

Purpose: The purpose of our work was to assess the value of abdominal sonography (US) and computed tomography (CT) in the preoperative diagnosis of appendiceal mucocele.

Material: and methods. We retrospectively reviewed 10 cases of mucocele of the appendix, 7 cases without pseudomyxoma peritonei, and 3 cases with pseudomyxoma peritonei.

[Abdominal actinomycosis. Report of 4 clinical cases studied with radiography].

We report 4 cases of pathologically proven abdominal actinomycosis. US and CT demonstrated an infiltrative abdominal mass with ill-defined margins and heterogeneous enhancement after IV contrast. The ileo-cecal region was involved in one case; the mass appeared following cholecystectomy and recurred 3 years after surgical resection in one case; and no predisposing factor was identified in the 2 other cases.

[Hydatic cysts of the liver ruptured into the thorax. Diagnostic and therapeutic aspects].

Hydatic cysts of the liver can rupture into the thorax. The aim of this work was to demonstrate how abdominal access can be used in most cases. We report 44 cases of hydatic cysts which ruptured into the thorax among a series of 1411 hydatic cysts of the liver operated between 1974 and 1995.
