[Arterial hypertension and stenosis of the accessory renal artery]. / Hipertensión arterial y estenosis de la arteria renal accesoria.

We present the case of a 45 year old patient with severe hypertension refractory to medical treatment who was diagnosed a significant stenosis of an accessory renal artery whilst the main renal arteries were normal. The arterial dilatation through angioplasty of the accessory artery improved dramatically the control of his hypertension.

Presentamos el caso de un paciente de 45 años con hipertensión arterial severa y refractaria al tratamiento médico a quien se objetivó una estenosis significativa de una arteria renal accesoria con normalidad de las arterias renales principales. La dilatación arterial mediante angioplastia de la arteria accesoria conllevó una mejoría significativa en el control de su hipertensión

Enhancement of intramammary lymph nodes with lymphoid hyperplasia: a potential pitfall in breast MRI.

We present three cases of breast lesions labeled as probable intramammary lymph nodes that showed an increase in size on follow-up mammography. Contrast-enhanced MRI was performed and the three lesions showed strong and rapid uptake of the intravenous contrast. Core needle biopsy established the diagnosis of lymphoid hyperplasia in all three patients. Because intramammary lymph nodes affected by benign processes can present findings similar to malignant lesions, the usefulness of contrast-enhanced MRI in these cases is controversial.
