Case ReportsBipartite parietal bone: a rare cause of plagiocephaly.
A case of an infant with an asymmetrical head is presented. On clinical assessment the patient displayed features of deformational plagiocephaly. With the aid of three-dimensional CT imaging of the skull, a bipartite parietal bone was diagnosed. The prevalence and possible aetiology of a bipartite parietal bone is discussed as well as a brief overview of the common causes of plagiocephaly.

Case ReportsSilent embolism in diagnostic cerebral angiography: detection with diffusion-weighted imaging.
Angiography has known and documented risks of neurological events. We prospectively studied 20 patients who underwent diagnostic cerebral angiographic examinations and diffusion-weighted MRI (DWI). ⋯ Diffusion-weighted MRI provides an objective means of detecting both clinical and subclinical neurological events. Diffusion-weighted imaging might therefore provide an easier method of assessing complication rates in cerebral angiography by reducing the number of patients required for meaningful statistical analysis.

Case ReportsRenal infarction secondary to a subcapsular haematoma following percutaneous renal biopsy.
We present the case of post-biopsy subcapsular haematoma leading to infarction of the kidney. This is a very uncommon complication of percutaneous renal biopsy. The radiological findings in this case are shown, highlighting the sonographic finding of the renal interlobar arteries having reversed flow in diastole in connection with very high resistance because of compression by a subcapsular haematoma. Although reversed diastolic flow has been well described in renal vein thrombosis, we know of no case report of this finding in association with severe ischaemia of the kidney due to tamponade.

A misplaced fine-bore nasogastric tube (NGT) might enter the bronchial tree. Pleural puncture and intrapleural passage of the tube is very uncommon but the location can often be inferred from the frontal chest radiograph. Following recognition of a NGT within the pleural space, progress films should be carefully screened for complications, particularly pneumothorax. This is often not done by staff involved in the monitoring of such patients because the staff frequently do not recognize the signs of intrapleural NGT insertion.

Case ReportsShocking abdominal trauma: review of an uncommon disorder of small intestine perfusion.
'Shock bowel' is a rare disorder of gastrointestinal physiology with characteristic radiological features. It usually occurs in the setting of blunt abdominal trauma and hypovolaemia, with complete reversibility of these findings following resuscitation. We present a case demonstrating the classic features of this complex of imaging findings thought to be caused by end-organ hypoperfusion.
