Acute mesenteric ischemia/infarction is a complex and often misdiagnosed syndrome. The availability of new imaging methods, namely multislice computed tomography, has enabled early recognition of signs and symptoms of acute mesenteric ischemia, resulting in timely therapeutic intervention.

Pneumatosis intestinalis may be caused by bowel ischemia and may display different patterns of appearance. We report a case of pneumatosis intestinalis with an atypical target pattern, detected by multidetector computed tomography (CT) in a 66-year-old male presenting with acute abdominal syndrome. ⋯ The patient was surgically treated and successfully discharged from our hospital with the diagnosis of acute bowel ischemia. The target air sign can be an initial CT finding of the typical pneumatosis intestinalis and it can be useful in the early diagnosis of bowel ischemia.

The aim of this study was to assess diagnostic accuracy of multislice CT in restaging patients with N2 non-small cell lung carcinoma after neoadjuvant chemotherapy, using a multiparametric approach as compared with traditional size-based radiological criteria. All patients staged as N2 at histologic examination after neoadjuvant chemotherapy were correctly staged with multislice CT (sensitivity, specificity, positive and negative predictive value, and accuracy were 100%, 80%, 85%, 100% and 93,7% respectively, vs 34%, 60%, 34%, 60% and 50% using size-based criteria), suggesting that a multiparametric approach results in improved diagnostic accuracy.

The purpose of this study was to evaluate the contribution of 18F-FDG-PET/CT in highlighting the peritoneal involvement in patients with ovarian cancer, also in relation to the biomarker CA125. We retrospectively analyzed 64 female patients with histological diagnosis of ovarian cancer who underwent 18F-FDG-PET/CT and CA125 measurement. ⋯ Sensitivity and specificity of CA125 were 93.33% (95% CI: 80-100%) and 33.33% (95% CI: 25-64%), respectively. In patients with peritoneal carcinomatosis from ovarian cancer, it is recommended to perform 18F-FDG-PET/CT, in particular when elevated CA125 levels are detected.

Case Reports
[Cough-induced intercostal lung herniation successfully diagnosed with imaging techniques].
We report the case of a 78-year-old man presenting with pain in right hemithorax that occurred suddenly after coughing. A palpable chest wall mass, soft in consistency, was noted on physical examination, and chest X-ray and CT allowed to make diagnosis of spontaneous lung hernia.
