The Effect of Diabetes Control Status on CT Findings in Pulmonary Tuberculosis: Emphasis on Bronchial Erosive Changes.

Purpose: Studies on the effect of diabetes mellitus (DM) on the radiologic findings of pulmonary tuberculosis (PTB) have reported inconsistent results. These findings may have been influenced by the glycemic control status of the patients studied. To our knowledge, no recent data have described the effect of the DM control status on CT findings in PTB in terms of medium-sized airway involvement that is visualized as bronchial erosion on CT.

The Atypical Manifestation of Pulmonary Tuberculosis in Patients with Bronchial Anthracofibrosis.

It has been stated that bronchial anthracofibrosis (BAF) has an important relationship with pulmonary tuberculosis (TB), and the coexistence of TB and BAF is high. The purpose of this study was to compare the differences in computed tomography (CT) characteristics of pulmonary TB according to the presence of underlying BAF. Total of 202 consecutive patients who were diagnosed with pulmonary TB and underwent bronchoscopy and CT in our institution were retrospectively reviewed.

Unusual presentation of granulomatosis with polyangiitis causing periaortitis and consequent subclavian steal syndrome: A case report.

Background: Granulomatosis with polyangiitis (GPA) is a rare autoimmune disease that involves small-to-medium-sized vessels and forms necrotizing vasculitis with granulomatous inflammation. The formation of a large vessel lesion in GPA patients has been scarcely reported, and it can cause confusion in the diagnosis.

Dynamic CT and MRA findings of a case of portopulmonary venous anastomosis (PPVA) in a patient with portal hypertension: a case report and review of the literature.

Portopulmonary venous anastomosis (PPVA), which has been rarely reported in conventional CT and MR studies, is an unusual collateral pathway in patients with portal hypertension. It has clinical implications related to right-to-left shunt that are different from the clinical implications related to other more usual portosystemic shunts in portal hypertensive patients. Here, we report the dynamic CT and MRA findings of a case of PPVA in a patient with portal hypertension, directly demonstrating the shunt flow from the paraesophageal varix to the left atrium via the right inferior pulmonary vein.

The internal mammary vessels above and below the first rib on multidetector CT: implications for anatomical feasibility of lung biopsy via anterior approach.

Purpose: To provide the anatomical knowledge necessary to draw biopsy routes by using an anterior approach above and below the first rib to avoid internal mammary vessel damage.

Materials And Methods: The anatomy of internal mammary vessels above and below the first rib was assessed by thin-section computed tomography (CT) analysis of 61 adults. The visibility of the internal mammary vessels, the relationship with the brachiocephalic vein, and the distance from the first rib (window width for biopsy) were determined above the first rib, whereas whether and where the internal mammary artery (IMA) and/or internal mammary vein (IMV) crossed the rib margin were assessed below the first rib.
