Myocardial contusion after a chest trauma is a frequently under-diagnosed injury. We report two cases of myocardial contusion in which MR imaging, thanks to its contrast capability, was able to assess the presence of a haematoma and in one case to demonstrate the recovery of the lesion.

Review Case Reports
Inadvertent intrathecal use of ionic contrast agent.
Intrathecal administration of ionic contrast media may cause severe and fatal neurotoxic reactions due to their hyperosmolarity and ionic nature. They are therefore strictly contraindicated for all radiologic applications involving the central nervous system (e.g., myelography). We present a case in which ioxitalamate was accidentally injected intrathecally. The patient recovered completely due to a combination of the different therapeutic options reported in the literature, including early mechanical ventilation and neuromuscular paralysis, aggressive control of seizures, elevation of head and trunk to prevent cephalad migration of contrast, steroids, cerebrospinal fluid drainage and lavage and prophylactic antibiotics.

Review Case Reports
Aneurysmal re-rupture during selective cerebral angiography.
Two cases of aneurysmal re-rupture during intracranial angiography are presented. This event is accompanied by disastrous consequences with regard to the clinical condition of the patient, as is evident from the cases presented as well as from the literature. Acute alterations of intraluminal pressure as well as a time interval of less than 6 h seems to increase the risk of re-bleeding during angiography. The introduction of and the growing experience with CT and MR angiography may in the near future provide sufficient diagnostic information for surgical planning and thus help to overcome the risk of aneurysmal re-rupture during intra-arterial angiography.

Presentation with acute abdominal pain or abdominal symptopathology is a very common cause of presentation of children to hospital. The causes are dependent in part on the age of the child, in part on the presence of previous surgery, and can be divided into those that relate to congenital abnormalities at whatever age they present, acquired disease and infection. Children, particularly young children are often poor historians, and therefore the clinical examination and the laboratory investigations are important in helping to come to a diagnosis. ⋯ The three commonest causes of acute abdominal pain in childhood are, in young infants, intussusception, appendicitis and mesenteric adenitis. In older children, inflammatory bowel disease and ovarian pathology are also included. This article details the approach to imaging and the salient features of some of the conditions.

The most likely etiology of benign obstruction of the superior vena cava (SVC) include fibrosing mediastinitis and iatrogenic etiologies such as sclerosis and obstruction caused by pacemakers and central venous catheter. Percutaneous stenting of SVC has been used with success both in malignant and benign superior vena cava syndrome; however, long-term follow-up of endovascular procedures is not well known. We present a case of a patient with complete occlusion of SVC of benign etiology, presenting dramatically with bilateral chylothorax and chylopericardium with cardiac tamponade, who underwent successful vena caval revascularization with thrombolytic therapy and placement of self-expanding metallic stent. The 42-month follow-up could encourage endovascular procedures even in SVC syndrome of benign etiology.
