ABSTRACT
PURPOSE: The purpose of this study was to retrospectively evaluate the effectiveness of integrated positron emission tomography-computed tomography (PET-CT) in comparison with contrast enhanced CT (CE-CT) in pre-operative staging of non-small cell lung cancer (NSCLC) by using surgical and pathological findings as the reference standard. MATERIALS AND METHODS: From August 2008 to August 2009, 57 consecutive patients (50 males and 7 females; mean age, 59 years; range, 38-79 years) with NSCLC underwent conventional pre-operative lung cancer staging using clinical data and CE-CT of the chest, and integrated whole-body fluorine-18 fluorodeoxyglucose PET-CT studies. Histopathological results served as the reference standard. RESULTS: Forty-eight of the 57 patients (84%) had no lymph node involvement (N0), five (9%) were found to have N1 disease, and four (7%) had N2 disease. There was a significant difference between CE-CT and PET-CT for nodal staging of N0 disease (P < 0.05). Sensitivity, specificity, positive predictive value, negative predictive value, and accuracy of hilar and mediastinal lymph node staging were 56%, 73%, 28%, 90%, and 70%, with CE-CT, respectively; and 78%, 92%, 64%, 96%, and 89% with PET-CT, respectively. CONCLUSION: Integrated PET-CT is more accurate than CE-CT for lymph node staging in NSCLC.

We report a successful repair of a ruptured tuberculous pseudoaneurysm of the descending thoracic aorta by endovascular stent graft placement. This procedure is starting to be accepted as an alternative method to surgery, and we review similar cases in the literature.

Arteriovenous fistula (AVF) of the scalp is a very rare complication of hair transplantation. Only 9 cases have been reported in nearly half a century. The diagnosis is clinical but angiography is necessary for defining the angioarchitecture of the lesion. Due to technical developments, endovascular embolization has become the primary treatment for AVF of the scalp.
