RESUMO
Metastatic pulmonary calcification occurs in association with several disease processes and has a highly variable prognosis. In certain patients, it may prove fatal, and therefore prompt recognition of radiological signs is helpful for optimising patient management. We describe the progressive changes seen on CT in a 59-year-old man who had undergone renal transplant and subsequently developed metastatic pulmonary calcification. The merits of the different imaging techniques available and possible treatment options are reviewed.

Meckel's diverticulum is the most common congenital abnormality of the small bowel. The majority of patients with this anomaly will remain asymptomatic; however, several complications may occur, including obstruction, intussusception, perforation, diverticulitis, and gastrointestinal haemorrhage. These complications may produce a variety of different clinical features and radiological appearances. The purpose of this article is to review the potential imaging manifestations of Meckel's diverticulum and its complications and discuss the advantages and disadvantages of the imaging techniques available.

AIM: To examine the success and complication rates of radiological placement of post-pyloric feeding tubes, including those inserted with the assistance of a guide-wire. MATERIALS AND METHODS: Two hundred referrals (156 patients), between the dates of 5 April 2002 and 10 September 2004, were identified retrospectively from computerized records. Subsequently, the radiology reports and patients' notes were reviewed to evaluate the indications for post-pyloric feeding, success of placement, use of a guide-wire, and any complications. RESULTS: A post-pyloric tube was placed in the distal duodenum/jejunum in 183 (91.5%) patients and in the proximal duodenum or distal stomach in six (3%). A tube could not be inserted in 11 (5.5%) patients, and 51 (25.5%) of the insertions required the use of a guide-wire. Immediate complications were recorded in seven patients (3.5%): vomiting (n=5); hypotension and apnoea requiring naloxone (n=1) and hypoxia requiring endotracheal intubation (n=1). CONCLUSION: Radiological placement of post-pyloric feeding tubes has a success rate comparable with endoscopically placed tubes, and it rarely involves significant technique-related complications.
