Background.Lymphoedema of the operated and irradiated breast is a common complication following early breast cancer treatment. There is no consensus on objective diagnostic criteria and standard measurement tools. This study investigates the use of ultrasound elastography as an objective quantitative measurement tool for the diagnosis of parenchymal breast oedema.Patients and methods.The elasticity ratio of the subcutis, measured with ultrasound elastography, was compared with high-frequency ultrasound parameters and subjective symptoms in twenty patients, bilaterally, prior to and following breast conserving surgery and breast irradiation.Results.Elasticity ratio of the subcutis of the operated breast following radiation therapy increased in 88.9% of patients, was significantly higher than prior to surgery, unlike the non operated breast and significantly higher than the non operated breast, unlike preoperative results. These results were significantly correlated with visibility of the echogenic line, measured with high-frequency ultrasound. Big preoperative bra cup size was a significant risk factor for the development of breast oedema.Conclusions.Ultrasound elastography is an objective quantitative measurement tool for the diagnosis of parenchymal breast oedema, in combination with other objective diagnostic criteria. Further research with longer follow-up and more patients is necessary to confirm our findings.

We advocate that US-guided fine needle aspiration (FNA) combined with liquid-based cytology of axillary lymph nodes should be included in the preoperative staging of breast cancer.

Granulomatous lobular mastitis is a rare chronic inflammatory disease of the breast. The differential diagnosis with malign breast disease is often not easy. In most cases a surgical biopsy is needed for correct diagnosis. Idiopathic granulomatous mastitis is an exclusion diagnosis, based on the demonstration of a characteristic histological pattern, combined with the exclusion of other possible causes of granulomatous breast lesions. There is still no generally accepted optimal treatment. If surgery forms part of the treatment, a conservative approach seems to be adequate in most cases. Another option is a long-term steroid treatment. It is mandatory to exclude infectious causes of granulomatous mastitis before corticoid therapy is started.

We report on a 60-year-old man, seen at the emergency department because of severe left flank pain. Clinical diagnosis was that of renal colic. Overnight he became haemodynamically unstable and haematuria became massive, so multidetector CT (MDCT) was performed. MDCT with reconstructions can represent complex imaging findings in a more straightforward way compared with transverse images. Rupture of a renal artery aneurysm into the left pelvis was seen on coronal reconstructed CT images. Nephrectomy was performed. Rupture of a renal artery aneurysm into the pelvis is unusual and death is likely if diagnosis and treatment are delayed. The initial clinical presentation may be very similar to renal colic. MDCT allows timely and correct diagnosis of this unusual condition.
