We present the case of a 60-year-old male patient, with refractory ulcers in the groin. Ultrasoundand CT showed a large vascularized tumor of the kidney with cystic parts and inhomogeneous dynamic behaviour. Histology demonstrated Pyoderma gangrenosum (ulcer) and well differentiated adenocarcinoma (kidney). Pyoderma gangrenosum appears as paraneoplastic manifestation in about 7% of cases, especially in lymphomas and tumors involving the digestive tract.Particularities of the case consisted in the accidental discovery of the renal tumor, in spite of the lack of urinary syndromes...

We reported a 43-year-old man with right-foot numbness under the tentative diagnosis of tarsal tunnel syndrome. The initial ultrasound examination did not identify any remarkable findings at the level of the medial malleolus. Owing to the failure of conservative treatments, he was referred for US-guided injection of the tibial nerve. When tracking the entire course of the nerve, a ganglion cyst was observed on top of the tibial nerve, in proximity to the medial and lateral plantar branches. The symptom disappeared after surgical excision...

Transrectal prostate biopsies under ultrasonography guidance remain the gold standard for the detection of prostate cancer (PCa). Transrectal ultrasonography (TRUS), however, has a limited sensitivity in PCa detection. Prostate elastography (TRES) increases the sensitivity of a TRUS examination. Therefore, the aim of this review is to discuss the usefulness of TRES in prostate gland imaging for the diagnosis and management of prostate cancer based on published literature. The advantages of transrectal elastography were analysed in the context of better diagnostic performance provided by this method...

Even if imaging has developed considerably during the last decades there still exist several factors which limit its capacities. These factors can either limit the usage of a technique or degrade images making them difficult to interpret. Magnetic resonance imaging (MRI) has, as an absolute contraindication, the presence of metallic devices marked as "MRI unsafe" and metallic foreign bodies close to the eye or vital structures. Claustrophobia and artefacts reduce the application and performance of MRI in a significant proportion of patients...

AIMS: Thyroid volume has to be measured in goiters prior to radioiodine treatment to calculate the needed amount of radioactivity. Modern clinical equipment for ultrasonography shows the trend to smaller probes, so that larger goiters do not fit any longer into the probe's field of view. This study evaluated the feasibility and accuracy of stitching procedures applied to thyroid volumetric analysis performed using three-dimensional ultrasound (3D-US). MATERIAL AND METHODS: Ad hoc thyroid phantoms of different shapes (regular, nodular, thickened isthmus) and volumes (ranging between 50 and 400 mL) were developed...
