This lesion is most likely caused by (the
$$carcinoma%%embolus^^hypoxia&&pyogenic bacteria",
"Mr. Jones died suddenly at an interstate rest park. Witnesses said he had gotten out of his truck, walked a few paces and dropped over. The interstate logbook indicated he had just driven 12 hours continously. The following picture is of his pulmonary artery and its two major branches.
The cause of the condition ilustrated is
$$endothelial injury followed by platelet activation%%venous stasis leading to factor activation^^tobacco use leading to metaplasia and subsequent malignancy&&mucous plugging leading to sequestration and bacterial growth",
"Mr. Helms sure enjoyed his smokes. This photograph of one of his lungs best illustrates
$$bronchiectasis%%lobar pneumonia^^emphysematous changes&&normal morphology",
"HISTORY: This 52-year-old woman had chronic cough and episodes of fever for many years.
PHYSICAL FINDINGS: Temperature 38 C; decreased breath sounds over the right upper lobe of lung.
LABORATORY RESULTS: chest x-ray: cavitary lesion in the right upper lung lobe with consolidation pleural thickening and mediastinal shift to the right
CLINICAL COURSE: The patient received a full course of medical treatment, and the right upper lobe was resected. Her postoperative course was uneventful and she was discharged two weeks later.
Culture of the cavity in the lobectomy prior to therapy would most likely grow which of the following?
$$Aspergillus flavus%%Klebsiella pneumoniae^^Strep. pneumoniae&&Mycobacterium tuberculosis",
"Mr Gates, a 61 year old man, was brought to the emergency room by his daughter because of high fever, cough and confusion. He had been well until approximately one week before and had not been around anyone who was sick. His sputum was yellow and revealed many acute inflammatory cells upon microscopic exam.
The following picture is representative of what his lung looked like prior to instuting therapy
Given the history and appearance of the photo, the most likley agent of this disease
$$Streptococcus pneumoniae%%Hemophilus influenzae^^Mycoplasma pneumoniae&&Pseudomonas aeruginosa",
"HISTORY: Mr. Helms, 63-year-old man, underwent total cystectomy 5 years previously for transitional cell carcinoma of the bladder. Since that time he had been well except for a persistent productive cough and mild dyspnea of 6 months duration. For the past month, sputum had been pink in the morning. During routine clinical follow-up exam, a left upper lobe mass was noted on chest x-ray. He had a 60 pack-year history of cigarette smoking.
PHYSICAL FINDINGS: Lungs were clear to percussion; hoarse, sonorous sounds were present over the left upper airway upon deep breathing.
The following two pictures are of lung lesion. The unifying factor in evaluating this patient's clinical history is
$$previous transitional cell carcinoma of the bladder%%cigarette smoking^^productive cough&&sputum color",
"The next picture shows two sections of lung, one normal and one abnormal. The process in the abnormal lung is most likely
$$alveolar cell carcinoma%%bronchopneumonia^^miliary tuberculosis&& fibrosis and bronchiectasis",
"Mr. Robertson worked as an auto mechanic for 35 years. He now presents with an peripheral pulmonary mass. The following picture is of that lesion. The diagnostic material is
$$calcium%%silica^^asbestos&&mycelia",
"The origin for the process that would cause this lung lesion was most likely
$$in the deep veins of the leg%%aspiration of gastric contents^^occult carcinoma&&silicosis with tuberculosis",
"The next two pictures refer to the evaluation of a 28 year old man with chronic cough. The first is his chest X-Ray and the second is a bronchoalveolar lavage stained with Gomori methenamine silver.
What underlying disease would be most likely in this patient?
$$systemic lupus erythematosus%%lobar pneumonia^^ histoplasmosis&&AIDS"
