Hepatic haemangioma: common and uncommon imaging features.

The haemangioma, the most common non-cystic hepatic lesion, most often discovered by chance, may in certain situations raise diagnostic problems in imaging. In this article, the authors first demonstrate that the radiological appearance of the hepatic haemangioma, in its typical form, is closely related to three known histological sub-types. They then show that certain atypical features should be known in order to establish a diagnosis. They also observe the potential interactions between the haemangioma, an active vascular lesion, and the adjacent hepatic parenchyma. Finally, they discuss the specific paediatric features of hepatic haemangiomas and illustrate the case of a hepatic angiosarcoma.

Solid pseudopapillary neoplasm of the pancreas

We report two cases of pancreatic neoplasm which were revealed as pseudopapillary tumour on histopathology report and both of the patients are doing well in follow up.

Fat-containing lesions of the liver : A pictorial essay

The presence of fat within a hepatic lesion is unusual and can help to direct the radiologists diagnosis. The aim of this iconographic review is to specify the various hepatic lesions that may contain fat and their appearance particularly on MRI. A histological correlation is also suggested for the most commonly found tumors. The identification of fat within a hepatic tumor, along with other radiological signs and reflection on the clinical and epidemiological context, can lead to a diagnosis being reached or suggested, with confirmation if necessary, by a pathological examination.

Tumeur pancréatique caudale chez une jeune patiente

Madame K., patiente âgée de 37 ans, consulte aux urgences pour des douleurs abdominales prédominantes dans l’hypochondre et la fosse iliaque droite. Cette patiente présente dans ses antécédents une plastie sphinctérienne anale pour incontinence consécutive à un accouchement traumatique. L’examen clinique retrouve une fièvre à 38,8 ◦C et un abdomen douloureux de façon diffuse. Le bilan biologique d’entrée met en évidence un syndrome inflammatoire (leucocytes : 18 000 mm3 et CRP : 150 mg/L) sans cytolyse ou cholestase. La bandelette urinaire est négative. Devant l’intensité des douleurs, un scanner abdominopelvien avec injection est réalisé (Fig. 1) à la recherche d’une appendicite aiguë ou d’une cholécystite aiguë. Le diagnostic de cholécystite aiguë est porté devant la distension et l’épaississement pariétal vésiculaire. Il est également découvert de manière fortuite une tumeur de la queue du pancréas pour laquelle un bilan complémentaire par IRM est effectué (Fig. 2).
