Southwest Journal of Pulmonary, Critical Care and Sleep

The September 2014 Arizona Thoracic Society meeting was held on Wednesday, 9/24/14 at the Kiewit Auditorium on the University of Arizona Medical Center campus in Tucson beginning at 5:30 PM. This was a dinner meeting with case presentations. There were about 21 in attendance representing the pulmonary, critical care, sleep, pathology and radiology communities.

Four cases were presented:

Mohammad Dalabih presented a 22 year old hypoxic man with a history of asthma and abdominal pain. A bubble echocardiogram showed bubbles in the left ventricle within 3 heartbeats. Thoracic CT scan showed a pulmonary arteriovenous malformation (AVMs). The patient underwent coil embolization and improved. Dr. Dalabih reviewed the diagnosis and management of pulmonary AVMs (1). Aarthi Ganesh presented a 70 year old woman complaining of dyspnea on exertion. A chest x-ray showed complete opacification of the right hemithorax and a thoracic CT scan showed a large right pleural effusion with right lung atelectasis. After thoracentesis was nondiagnostic, she underwent video-assisted thorascopic surgery (VATS). Although she clinically appeared to have mesothelioma, histology was consistent with a pseudomesotheliomatous adenocarcinoma. She is currently undergoing treatment with platinum based agents.
Gordon Carr presented a 75 year old woman with dyspnea. Chest x-ray showed interstitial disease with a possible usual interstitial pneumonia (UIP) pattern on CT scan. Dr. Carr reviewed the initial evaluation and diagnosis of the interstitial lung disease (2). VATS showed a bronchocentric process with some fibrosis in the periphery most consistent with chronic hypersensitivity pneumonitis. The likely source was thought to be mold in her indoor pool area.
James Knepler presented a 55 year old woman with breast cancer and bone metases receiving tamoxifen. She also had a history of multiple sclerosis and was receiving on interferon-beta 1a. A positron emission tomography (PET) scan showed increased uptake in several mediastinal lymph nodes. Endobronchial ultrasound (EBUS) guided aspiration biopsy was non-diagnostic. Endobronchial biopsy showed granulomas. It was felt the most likely diagnosis was interferon-induced sarcoidosis. Several case reports have recently been published.

There being no further business the meeting was adjourned about 7:00 PM. The next meeting will be Phoenix on Wednesday, October 22, 6:30 PM at Scottsdale Shea Hospital.
