RESUMEN
Hepatic macronodular mycobacteriosis is rare. Its diagnosis is challenging and is most often proposed on the basis of histological analysis. Final diagnosis, except for germ-proven cases, is made in conjunction with clinical, biological, and radiological arguments. We retrospectively report the MR features of ten hepatic lesions discovered on five patients. MRI is sensitive but has a low specificity in demonstrating pseudotumoral lesions most often exhibiting hypointensity on the T1-weighted sequence, hyperintensity on the T2-weighted sequence, and a slight rim enhancement after gadolinium-enhanced T1-weighted sequences.

In cases of transjugular liver biopsies, the venous angle formed between the chosen hepatic vein and the vena cava main axis in a frontal plane can be large, leading to technical difficulties. In a prospective study including 139 consecutive patients who underwent transjugular liver biopsy using the Quick-Core biopsy set, the mean venous angle was equal to 49.6 degrees. For 21.1% of the patients, two attempts at hepatic venous catheterization failed because the venous angle was too large, with a mean of 69.7 degrees. In all of these patients, manual reshaping of the distal curvature of the stiffening metallic cannula, by forming a new mean angle equal to 48 degrees , allowed successful completion of the procedure in less than 10 min.

Pelvic magnetic resonance is a simple and non-invasive imaging technique for dynamic and static assessment of the pelvic floor. The morphology of the support system is assessed by T2-weighted images. Dynamic sequences are used to assess pelvic prolapse. In this study we illustrate the normal and pathologic features of the levator ani muscle which represents the main active support of pelvic organs. Furthermore we describe the different types of prolapses, floor by floor, and the different staging techniques.
