The findings of ultrasound examination at and around the lateral humeral epicondyle in 41 tennis players suffering from so called tennis elbow are reported. Ultrasound examinations were performed with a real time ultrasound machine. The tenderness and functional impairment of tennis elbow may be caused by several different lesions, at times appearing in association. Six ultrasonographic characteristics could be identified:Enthesiopathy The proximal part of the tendon was enlarged and there were echogenicity alterations. Tendonitis The tendon of the extensor carpi radialis brevis was enlarged and areas of dyshomogeneous hypoechogenicity were evident with loss of the normal microscopic waveform structure of the tendon collagen.Peritendonitis A thickening of the peritendonous lining was present. Bursitis A bursa was located on the inferior surface of the tendon of the extensor carpi radialis brevis. Intramuscular haematoma Some circular or ovoid hypoechogenic areas within the muscular substance of the extensor carpi radialis brevis were evident. Mixed lesions These were not correlated with the intensity and the duration of the symptoms.Ultrasonographic examination gives a detailed iamge of the structures involved in the tennis elbow syndrome, confirms the diagnosis, and may be useful in monitoring treatment.

Fifty-two knees were examined using real-time highdefinition ultrasonography with a 7.5MHz probe. The extra-articular structures were easily visualized and diagnosis of patellar tendon lesions and Baker's cysts formulated. While the meniscal cartilages were shown as a homogeneous triangular structure between the femoral condyle and the tibial plateau, no lesions were detected. Deeper intra-articular structures, such as the cruciate ligaments, were not shown by the scan, thus their evaluation was not possible. Given its low cost, wide availability, non-invasiveness and patients' acceptability of the technique, ultrasonography may play an important role in the diagnosis of soft tissue lesions in and around the knee joint.

MSCT with a single-phase technique is an accurate and reproducible method for diagnosis and evaluation of disease resectability in patients with suspected PC, ensuring optimal tumour-to-pancreas contrast and maximal opacification of the main peripancreatic arterial and venous structures.

In presenting the case of a 61-year-old man with a primary squamous carcinoma in a bladder diverticulum, the authors stress the usefulness of applying all the available modalities of imaging, since it has been found that a bladder diverticulum may harbor a neoplasm more often than a normal bladder.
