[Breast hematoma and cytosteatonecrosis. Apropos of 55 cases]. / Hématome et cytostéatonécrose mammaire. A propos de 55 observations.

The authors report a retrospective study of 55 cases, 34 hematomas and 21 cytosteatonecrosis (CSN) of the breast, during 15 years. The mammary hematoma can appear with an encapsuled or diffused form, or in 40% of cases without radiographic model. The diagnosis of CSN, is easy, such as ringed, macrocalcified, or oil cystic, but when it is the case of solid cicatriciel mass, it is difficult to distinguish it from mammary carcinoma, in approximatively half of the cases. The etiopathogenic discussion, display, traumatic features, ischemic cellular disease, such as mammary infarct, inflammatory lesions, duct ectasia, anticoagulant drugs, needle aspiration... Even though nodular lesion may be a carcinoma, a very suggestive lesion with spicules and skin retraction may be benign. The follow up, or histological examination by biopsie or surgery, is always essential.

[Thrombophlebitis of the right ovarian vein. X-ray computed tomographic diagnosis and monitoring of 2 cases]. / Thrombophlébite de la veine ovarienne droite. Diagnostic et surveillance scanographique de deux cas.

We report two cases of post partum right ovarian vein thrombophlebitis: The aspect of the C.T. is presented, specifying the anatomic relations of the right ovarian vein. The C.T. progression under treatment is illustrated in one case by the appearance of a vena cava thrombosis and in another by a return to normal. The possibility of other examinations is discussed. Correct knowledge of these C.T. findings should allow a diagnosis and a treatment without invasive procedures.

[Renin-secreting tumor detected by MRI]. / Tumeur à rénine découverte par IRM.

We report an uncommon case of small renin secreting tumor of the kidney located in the medulla. The tumor was primarily detected by MRI and subsequently studied by spiral CT. The results and limitations of both techniques are discussed.

[Abrikossoff's tumor with bronchial localization. Contribution of x-ray computed tomography in a new case]. / Tumeur d'Abrikossoff à localisation bronchique. Apport de la tomodensitométrie à l'occasion d'un nouveau cas.

The authors present a case of Abrikossoff's tumor located in the segmental bronchus and detected on a systematic chest radiography, diagnosed during an endoscopy is reported. The CT study specified the tumoral extension. Bronchial distal affections is very rare. A confrontation with the anatomopathological data allowed a better understanding scanographic aspect.
