title: V/Q Matched Defect Larger than Hiatal Hernia Itself.
abstract: We present the case report of a patient 83 year old female who developed progressive shortness of breath and subsequently underwent scintigraphic evaluation of her symptoms with a ventilation/perfusion scintigraphic exam. A matched perfusion defect was seen involving the basal segments of the left lower lobe. Following this, the patient was examined with a contrast enhanced CT of the chest to further investigate the defect, which revealed compression of the bronchi and vasculature of the left lower lobe basal segments by the hernia larger than the actual hernia. To our knowledge there has not been a case report of a large hiatal hernia as a cause of matched lower lobe defect.
