ABSTRACT
Carcinoid tumor is often a late diagnosis due to the unspecificity of symptoms leading the radiologist rely on different investigation procedures. We present a case illustrating the contribution of US by demonstrating the suggestive combination of radiating mesenteric densities with a mesenteric mass.

Although arthrography of the TMJ is nowadays considered as old-fashioned, the technique remains a valuable alternative in cases where MRI is contraindicated. The authors discuss the technique of inferior joint space arthrography and present a review of typical arthrographic cases of the most common types of TMJ pathology.

A case of large pedunculated gastric leiomyoma with intermittent prolapse into the duodenum, causing a somewhat confusing clinical picture is presented. Ultrasound-, CT- and barium studies clearly showed the origin and extent of the tumor. Sonography was the only imaging method that showed intermittent prolapse of the tumor during examination. Imaging studies did not allow prediction of the benign nature of the tumor.

One of the major disadvantages of sagittal arthrotomography of the temporomandibular joint is its limited capability to detect sideways (medial or lateral) disk displacement. Several arthrographic signs, suggesting sideways disk displacement have been described in recent reports. The most important one is the edge sign. In doubtful cases, arthro-CT can be used for depiction of medial or lateral disk displacement.

Clinical, arthrographic and surgical findings in 20 patients who showed persisting TMJ-pain or dysfunction after an acute traumatic event were reviewed and compared to findings in a control group of 65 patients who did not remember an acute post-traumatic onset of symptoms. Anterior disk displacement (82%), disk perforation (65%) and rotational anteromedial disk displacement (34%) were the most common abnormalities encountered. Other important abnormalities were joint adhesions and capsule perforation. When compared with the control group, all these abnormalities occurred more often in traumatised joints. Arthrography was found to be highly accurate in detecting most types of abnormalities found during surgery. Arthrography is reported to be more effective than MRI in detecting disk perforations, adhesions and capsule perforations, which points to its continuing importance as an imaging tool for evaluating post-traumatic temporomandibular joint disorders.

Rapidly destructive coxarthrosis is a rather rare disease that affects most frequently women between 60 and 66 years. This bone disease is defined by a rapid chondrolysis with total obliteration of the joint space in the superolateral segment of the joint in an average period of one year, followed by rapid bone destruction of the femoral head and the roof of the acetabulum. This periarticular osteolysis causes a rising of the femoral head. The radiographic appearance shows minimal osteophytosis but this is never absent. The study of follow-up radiographs is helpful to make a choice in the differential diagnosis among the ethiologies of a rapidly destructive hip.

Three cases of dilated abdominal left paraaortic lymphatic duct are described. The diagnosis was established by means of sonography and confirmed with lymphography in all three patients. A sonographically guided puncture of the lymphatic duct was performed in one patient. Dilatation of these lymphatic ducts was possibly the consequence of previous upper abdominal surgery in two patients and a coronary bypass operation in one.
