Acute abdomen is a serious clinical situation and prompt imaging is mandatory so that appropriate therapeutic measures can be taken. Multiple diseases can present with the clinical signs and symptoms of acute abdomen. Ultrasound is widely available and can be performed expeditiously. ⋯ Contrast-enhanced ultrasound is among these valuable innovations. In this article the application of modern ultrasound techniques for the diagnosis of the most common causes of acute abdomen is outlined, which may be due to diseases of the gastro-intestinal tract, parenchymal organs in the upper abdomen as well as vascular disorders. Moreover, the diagnostic efficacy and the value as compared to other imaging modalities are analyzed.

Although diseases of the paranasal sinuses have a relatively homogeneous clinical presentation, their causes can vary considerably. Radiological imaging only became relevant in paranasal sinus diagnostics following the introduction of cross-sectional imaging. ⋯ Particularly in acute inflammatory diseases as well as traumatic lesions, imaging is essential in preoperative planning and postoperative control. The article gives a detailed description of options in radiologic imaging of the paranasal sinuses.

Case Reports
[Acute compartment syndrome of the forearm after paravasation of contrast medium. Case report].
The paravasation of radiographic contrast medium has a wide spectrum of clinical presentations, ranging from local erythema and swelling to extensive damage to the extremity affected. We report the case of a patient who developed an acute compartment syndrome of the forearm after paravenous mechanical injection of 100 ml radiographic contrast medium. After emergency fasciotomy for muscle and nerve decompression the full range of motion and sensitivity could be restored.
