RESUMO
Isolated teres minor denervation is an uncommon finding on sonographic examination. We present a case of a 64-year-old man with increased echogenity of the teres minor muscle and a slight reduction in muscle bulk. Investigation of a suspected axillary nerve lesion included a detailed sonographic examination of the posterior shoulder and the axillary space, followed by MR imaging and electrophysiologic testing. This case demonstrates the potential importance of examining rotator cuff muscles when performing sonographic examination of the shoulder in patients with persistent symptoms, no history of trauma, and absence of tendon tears.

We report the unusual case of a 54-year-old man with a right atrial mass (detected by two-dimensional echocardiography) associated with hepatocellular carcinoma. The cardiac mass, following magnetic resonance imaging of the heart, was proved to be due to a direct extension of the liver tumour, via the inferior vena cava, up to the right atrial cavity. We wish to stress that the availability of magnetic resonance imaging renders possible the antemortem diagnosis of cardiac metastasis due to malignant tumours.
