Ultrasound examination of the sublingual region is a non-invasive, safe, inexpensive and widely available procedure, unaffected by the amalgam in teeth which is a source of considerable artefact on CT and MRI images. With a little practice and good understanding of the anatomy, ultrasound can be a very helpful primary examination. If the lesion is clearly seen, no further imaging may be required.

Case ReportsPercutaneous radiological management of high-output chylothorax with CT-guided needle disruption.
We present the study of a 58-year-old man who underwent percutaneous management of a high-output chylothorax following cardiac bypass graft surgery. The patient presented to a peripheral hospital 3 weeks postoperatively following cardiac bypass graft surgery with shortness of breath. ⋯ The patient was treated conservatively with no improvement until undergoing a CT-guided needle disruption of lymphatics with good effect. This case is presented to show the minimally invasive treatment methods that are available in the management of high-output chylothorax.

Case ReportsAbdominal cerebrospinal fluid pseudocyst: a complication of ventriculoperitoneal shunts in adults.
Abdominal cerebrospinal fluid pseudocyst is an uncommon complication of using ventriculoperitoneal shunt (VPS). Although many cases have been reported in children, abdominal pseudocysts are rare in adult patients. The purpose of this article is to describe and illustrate the findings for this condition on commonly used abdominal diagnostic imaging modalities. ⋯ Plain-film radiography was carried out in one patient, ultrasound in three and CT in all six. A fluid collection close to or associated to the VPS catheter was observed in all cases. Visualization of the distal tip of the VPS within a homogeneous intraperitoneal collection is the principal diagnostic sign of an abdominal cerebrospinal fluid pseudocyst at ultrasound and CT.

ReviewInterventional radiology in the provision and maintenance of long-term central venous access.
Establishing and maintaining venous access forms an increasing proportion of the workload in interventional radiology. Several patient groups require medium-term to long-term venous catheters for a variety of purposes, including chemotherapy, long-term antimicrobials, parenteral nutrition, short-term access for haemodialysis or exhausted haemodialysis. ⋯ Venous access devices include implantable catheters (ports), tunnelled catheters and peripherally inserted central catheters, which have different functions, advantages and limitations. Imaging-guided placement is the preferred method of insertion in many institutions because of higher success rates and radiologists are well suited to address catheter complications.
