Survival in oesophageal cancer remains poor with high post-operative recurrence rates. PET/CT was introduced to the Three-Counties Cancer Network (3CCN) in 2006 to detect 'occult' metastatic disease not seen with conventional staging modalities. This study aims to determine whether the introduction of Integrated fluorodeoxyglucose (18F) Positron Emission Tomography (PET/CT) has changed the management, improved survival or reduced the rate of early post-operative recurrence in patients with operable oesophageal cancer. A retrospective review was undertaken of all patients diagnosed with oesophageal cancer in the 3CCN from 2005 to 2009. Early recurrence was defined as proven recurrence locally or at a distant site within one year of resection. 725 patients were identified. 200 (27.6%) patients underwent staging PET/CT. PET/CT altered treatment intent in 19 (9.5%) patients. 128 (17.7%) patients underwent oesophageal resection, 90 (70.3%) of which had a staging PET/CT. No significant difference was noted in post-operative mortality (4.4% Vs 5.3%, p = 0.8) or early recurrence where PET/CT was performed when adjusted for age, sex, stage or neo-adjuvant chemotherapy (p = 0.761, OR 1.136[95% CI 0.499-2.585]). PET/CT had no significant effect on survival (log-rank test; Chi-square 0.710, p = 0.4). PET/CT has improved the accuracy of oesophageal cancer staging avoiding potentially unnecessary surgery. Ultimately however, its use has had no effect on early recurrence or survival rates. Inaccurate identification of occult metastatic disease prior to the introduction of staging PET/CT does not appear to be the primary cause of early recurrence in patients with oesophageal cancer.

Fractures of the thoracic and lumber spine are well recognized following an epileptic seizure. Fractures of the cervical spine are not. The rare occurrence of a displaced odontoid fracture type 2, secondary to a grand mal seizure is presented. To our knowledge, this association has not been described previously in the English literature.

Budd-Chiari syndrome occurs when venous outflow from the liver is obstructed. The obstruction may occur at any point from the hepatic venules to the left atrium. The syndrome most often occurs in patients with underlying thrombotic disorders such as polycythemia rubra vera, paroxysmal nocturnal hemoglobinuria and pregnancy. It may also occur secondary to a variety of tumours, chronic inflammatory diseases and infections. Imaging plays an important role both in establishing the diagnosis of Budd-Chiari syndrome as well as evaluating for underlying causes and complications such as portal hypertension. In this review article, we discuss the role of modern imaging in the evaluation of Budd-Chiari syndrome.

Pancreatic insulinomas are rare tumours of the islet cells of the pancreas, which account for the majority of functional neuroendocrine tumours of the pancreas. There is often a typical history of recurrent hypoglycaemic collapse and dizzy spells. Insulinomas are usually solitary, and the vast majority are intra-pancreatic in location. They are characteristically small with approximately 66% being less than 2cm at presentation. Insulinomas continue to pose a diagnostic challenge to physicians, surgeons and radiologists alike. The role of imaging is to detect and provide precise anatomical localization and staging of tumours prior to surgery. Due to their small size at clinical presentation, they are notoriously difficult to localize radiologically, and specifically designed protocols are necessary to aid detection. In this review, we describe the current "state of the art" imaging protocols that may be used in the preoperative localization of insulinomas.
