The scintigraphic findings in a rare case of a unilateral matched ventilation perfusion defect, Swyer-James (Macleod's) syndrome, are presented. A 40-year-old man underwent ventilation/perfusion imaging for acute onset of dyspnea. The scan showed markedly diminished ventilation, vascular flow, and perfusion unilaterally on the left hemithorax. Chest radiography showed hyperlucency of the left lung. Pulmonary angiography showed left-sided hypovascularity, and the CT scan of the chest showed apical bullae and peribronchial thickening of the left lung. Ventilation/perfusion imaging and other radiologic assessment, along with the patient's medical history, confirmed the diagnosis of the Swyer-James syndrome. This condition should be considered as a differential diagnosis in a patient with unilaterally matched ventilation/perfusion deficits without an obvious etiology.
Girls with UTI should not be considered to be a homogeneous group. The frequency of VUR is related to T(max) and inversely to age. Data about these subpopulations should be used in deciding which girls should undergo cystography.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
