Schmidt - University of Michigan, Ann Arbor, MI Clinical Summary: The patient is a 12-year-old female who presents to her primary care physician with complaints of a 25 pound weight loss over 6 months, decreased appetite, a cough productive of brown sputum over the past two months, and occasional emesis. A plain chest x-ray was performed, showing diffuse interstitial opacities that are nodular in appearance and involve all lobes of both lungs. These changes are somewhat more pronounced in the lower lobes. By history, she lives in a rural setting and has exposure to both a barn and handles hay on a regular basis. She has no significant travel history or tuberculosis exposure. She was treated for pneumonia at the age of 4 but otherwise has no significant past medical history. One parent smokes in the home. Her physical exam is normal except for faint bibasilar crackles and digital clubbing. She is referred to a pediatric pulmonologist, who sends her for an open lung biopsy. Pertinent Laboratory Data: The patient has had a normal sweat chloride test. A sputum culture sent for acid fast bacilli was negative. Pulmonar function testing reveals moderate to severe restrictive disease with some air trapping and a low DLCO.

CT: One week prior to admission: Peribronchial soft tissue infiltration with bronchial narrowing. Focal nodular infiltrates. Bilateral small pleural effusion. Three days after admission: Marked progression of disease with accentuation of lymphatics, increased nodularity, consolidation, and increase in size of pleural effusions.

Jones - UCSF, San Francisco, CA Clinical Summary: 82-year-old woman with abnormal chest x-ray. A CT scan shows two adjacent right upper lobe nodules, both approximately 8 mm in diameter. A right upper lobe wedge resection was performed (9 x 3.5 x 2.8 cm) that showed a 1 cm diameter nodule.

Roden - Mayo Clinic, Rochester, MN Clinical Summary: This 42 year old man presented to the Emergency Department with sudden onset of sharp, non-exertional anterior chest pain. He denied any fever. The patient had a 25-pack year smoking history and also smoked marijuana for 20 years. Otherwise, his past medical history and family history were unremarkable. Physical examination revealed diminished bilateral breath sounds, bilateral coarse crackles, and markedly hyperinflated chest. He was treated with antibiotics for one week without clinical improvement. A chest X-ray was performed followed by a CT scan. Subsequently, the patient underwent wedge biopsy of the right middle and lower lung lobes.
