Role of multidetector computed tomography in the assessment of pancreatic injuries after blunt trauma: a multicenter experience.

Pancreatic injuries can occur from either penetrating or blunt abdominal trauma. While there are rare, especially in the setting of blunt abdominal trauma, they are associated with a mortality of up to 30%, and a morbidity of 60%. Multidetector computed tomography (MDCT) is the preferred imaging modality in patients with acute blunt abdominal trauma and for the detection of acute pancreatic injury.

Multidetector Computed Tomography of Pharyngo-Esophageal Perforations.

Perforation of the esophagus remains a diagnostic and therapeutic challenge. Currently, the most common cause of perforation is instrumentation of the esophagus, but other conditions such as foreign body, trauma, or spontaneous rupture are possible entities in the clinical practice. Multidetector computed tomography has become the imaging technique of choice in the evaluation of this setting of patients because of its capability to depict all the different signs associated with the degrees of wall impairment.

Diaphragmatic injuries: why do we struggle to detect them?

Diaphragmatic injury is an uncommon traumatic condition. It can be easily missed due to a lack of awareness by both clinicians and radiologists. A high index of suspicion is required for the establishment of an early diagnosis and prevention of life-threatening complications.

Erlotinib-induced complete response in a patient with epidermal growth factor receptor wild-type lung adenocarcinoma after chemotherapy failure: a case report.

Introduction: The efficacy of erlotinib in advanced non-small-cell lung cancer has been demonstrated in several trials, but only two cases of complete and prolonged response in wild-type epidermal growth factor receptor locally advanced lung cancer have been published.

Case Presentation: We discuss a case of a 67-year-old Caucasian man, a former heavy cigarette smoker, with a diagnosis of wild-type epidermal growth factor receptor locally advanced adenocarcinoma. After platinum-based doublet chemotherapy, when a progression of disease had occurred, a second-line therapy with erlotinib was started.

Role of imaging in the assessment of impacted foreign bodies in the hypopharynx and cervical esophagus.

Impaction of foreign bodies in the upper digestive tract is a serious pathologic condition in ear, nose, and throat practice and is particularly common in children, prisoners, and psychiatric patients. Commonly found objects include fish bones, chicken bones, pieces of glass, dental prostheses, coins, and needles. The goals of the initial patient assessment are to identify the type of object, its location in the gastrointestinal tract, the presence of any associated complications, and the presence of any underlying esophageal conditions.

Bleeding due to pelvic fractures in female patients: pictorial review of multidetector computed tomography imaging.

Pelvic bone fractures in female patients are a result of high-energy trauma and are a significant cause of morbidity and mortality. Their classification is based on the mechanism of the traumatic impact force and the evaluation of stability or instability of pelvic ring fracture. Vascular hemorrhage is frequently associated with pelvic bone disruption and is the main cause of death in polytrauma female patients.

Intensive-care unit lung infections: The role of imaging with special emphasis on multi-detector row computed tomography.

Nosocomial pneumonia is the most frequent hospital-acquired infection. In mechanically ventilated patients admitted to an intensive-care unit as many as 7-41% may develop pneumonia. The role of imaging is to identify the presence, location and extent of pulmonary infection and the presence of complications.

Esophageal injuries: spectrum of multidetector row CT findings.

Background: Aim of this study is to illustrate the multidetector row computed tomographic findings related to oesophageal injuries and their significance for therapeutic decisions.

Method: From April 2002 to April 2005 we studied 16 patients with suspected oesophageal injury. Ten patients underwent standard chest radiograph, while five patients with suspected foreign body ingestion were submitted to cervical plain film and gastrografin swallow study.

Adrenal injuries: spectrum of CT findings.

Injury to the adrenal gland is often incidentally diagnosed with Computed Tomography (CT) following blunt abdominal trauma. In a high percentage of cases, it is accompanied by other intra-abdominal, retroperitoneal or intrathoracic injuries. Although not usually clinically significant, adrenal traumatic lesions can be a source of infection, as well as a cause of acute adrenal insufficiency.

Pictorial essay: common and uncommon CT features of acute pelvic pain in the woman.

Acute pelvic pain in women is a frequent cause of emergency hospital admission. Because the source may be either gynaecological or non-gynaecologic and because of the complex anatomy of the pelvic area, the differential diagnosis of the underlying disease is extensive. In such cases ultrasonography is the procedure of choice, as it leads to a diagnosis in most cases.

Gallstone ileus analysis of radiological findings in 27 patients.

Purpose: We retrospectively compared the clinical value of plain abdominal film, abdominal sonography and abdominal CT in diagnosing gallstone ileus in 27 patients.

Material And Methods: 27 patients (23 women and 4 men, age range 58-96 years; mean age 71.5 years) with surgically proven gallstone ileus were submitted to plain film, sonography and CT of the abdomen.

Positive predictive value and negative predictive value of spiral CT in the diagnosis of closed loop obstruction complicated by intestinal ischemia.

Purpose: To assess the positive predictive value and the negative predictive value of spiral CT in the diagnosis of "closed-loop" obstruction complicated by intestinal ischaemia.

Materials And Methods: Between January 1999 and January 2002, 120 patients with small intestine closed-loop obstruction who had undergone surgical laparotomy within 2-6 hours from abdominal and pelvic spiral CT were retrospectively reviewed. The CT scans were performed using 5-mm slice thickness, 1 s scan delay, 5 x 5-mm collimation and 1.

Regarding three cases of descending necrotizing mediastinitis: spiral CT assessment.

Descending necrotizing mediastinitis (DNM) is a rare and life-threatening complication of deep neck space infection which occurs when infection spreads from the deep spaces of the neck, propagating within the soft tissue into the mediastinal spaces. The disease has a high mortality rate due to frequent delay in diagnosis and treatment. Computed Tomography (CT) is important in determining the level of infection, showing the presence and extension of fluid collections (with or without gas bubbles) and diffuse soft-tissue infiltration of the mediastinal fat, and indicating the best surgical approach and progress of treatment.
