ABSTRACT
Primary bone lymphoma has been defined as a solitary lesion in bone, without concomitant involvement of the extra osseous hematopoietic system, with no evidence of extra osseous disease within 6 months of the onset of symptoms. The vast majority of cases are of the large B-cell non-Hodgkin type. They are rare bone tumor. Distinguishing primary bone lymphoma from other bone tumors is important because the former has a better response to therapy and a better prognosis.

Ultrasound has been widely used for the evaluation of the shoulder, mainly for rotator cuff pathology. Developments in technology, as well as better knowledge of the pathology and the anatomy make this examination one of the most useful in the exploration of the shoulder, especially in the hands of the experienced radiologist. Ultrasound is low-cost, readily available and should be considered with plain films as the first step examination of the shoulder. Ultrasound is not only useful for the evaluation of the rotator cuff pathology and impingement syndrome, but is also performing in the evaluation of non rotator cuff pathology such as biceps tendon pathology, shoulder instability, mass evaluation, infection, degenerative and inflammatory arthropathies and nerve entrapment syndromes. Making a complete evaluation of the shoulder helps to differentiate between rotator cuff pathology and others that can mimic rotator cuff disorders. This article will review shoulder anatomy and examination technique and the different pathologies that can be assessed by ultrasound.

Anterior dislocation of the tibialis posterior tendon is a traumatic lesion, which is rarely suspected following ankle trauma. It seems to be promoted by hypoplasia of the retromalleolar sulcus. Surgical treatment is easy and reportedly gives excellent results, but the diagnosis is difficult and absence of diagnosis may result in functional instability of the foot requiring more invasive surgical treatment.

During the last decade, the hypothetical carcinogenic effects of mammography have lead to new technical developments in X-ray diagnosis and to the use of other imaging techniques such as ultrasonography (US), transillumination, magnetic resonance imaging (MRI). Many preliminary studies were published but few clinical trials are really convincing. According to the definition of a diagnostic tool, none of these new modalities is supposed to supplant mammography in the diagnosis of breast cancer. Improvements are expected by digital mammography in the near future.

A case of T10-T11 level calcified disk herniation of foraminal location is reported. Radicular pain was not precisely stated at the onset of complaints. Diagnosis was evoked by plain films and established by CT.
