Those who care for patients with pulmonary, critical care or sleep disorders rely heavily on chest radiology and pathology to determine diagnoses. The Southwest Journal of Pulmonary and Critical Care publishes case-based articles with characteristic chest imaging and related pathology. The editor of this section will oversee and coordinate the publication of a core of the most important chest imaging topics. In doing so, they encourage the submission of unsolicited manuscripts. It cannot be overemphasized that both radiologic and pathologic images must be of excellent quality. As a rule, 600 DPI is sufficient for radiographic and pathologic images. Taking pictures of plain chest radiographs and CT scans with a digital camera is strongly discouraged. The figures should be cited in the text and numbered consecutively. The stain used for pathology specimens and magnification should be mentioned in the figure legend.

Medical Image of the Month: Pectus Excavatum

Figure 1. A) PA chest radiograph at 38 years old demonstrates rib cage growth arrest at the time of pectus repair. B) and C) demonstrate the coronal and sagittal CT chest views.

 

Figure 2: Pulmonary function tests demonstrate severe restrictive ventilatory defect.

 

Clinical History

A 38-year-old man with obesity and history of pectus excavatum post-operative surgical repair at age 4 presented to the general pulmonary clinic with symptoms of severe dyspnea on exertion after walking one block. Chest x-ray and thoracic CT scan demonstrate anterior chest wall depression. (Figure 1). Pulmonary function testing demonstrated a severe restrictive lung disease (Figure 2).  High resolution CT demonstrated anterior chest wall depression. The Haller index was 2.5—mild excavatum—with associated scarring in the anterior right lung. Expiratory air-trapping was seen consistent with small airways disease.

Haller Index

The Haller index is calculated by dividing the transverse diameter of the chest by the anterior-posterior distance on the CT of the chest on the axial slice that demonstrates the smallest distance between the anterior surface of the vertebral body and the posterior surface of the sternum (1). Normal chest < 2.0; mild excavatum 2.0 – 3.2; moderate excavatum 3.2 – 3.5; severe excavatum > 3.5. Corrective surgery is considered for a Haller index of greater than or equal to 3.25.  Secondary thoracic dystrophy is a known consequence of too early repair of pectus excavatum (1).  Cases like our patient have changed when surgical repair is attempted until after puberty.

Learning Objectives: As a result of completing this activity, participants will be better able to:

  1. Interpret and identify clinical practices supported by the highest quality available evidence.
  2. Establish the optimal evaluation leading to a correct diagnosis for patients with pulmonary, critical care and sleep disorders.
  3. Translate the most current clinical information into the delivery of high quality care for patients.
  4. Integrate new treatment options for patients with pulmonary, critical care and sleep related disorders.

Learning Format: Case-based, interactive online course, including mandatory assessment questions (number of questions varies by case). Please also read the Technical Requirements.

CME Sponsor: University of Arizona College of Medicine at the Arizona Health Sciences Center.

Current Approval Period: January 1, 2019-December 31, 2020

 

Clinical History: A 66–year old woman presented with complaints of a non-productive cough worsening over the previous several weeks. She complained that her cough had also occurred several months earlier, but resolved, and then subsequently returned.

The patient indicated that she has had bouts of bronchitis off and on for many years. Her smoking history included only 3 cigarettes / day for two years, quitting 20 years earlier. She did not note any allergies and her list of medications included only vitamin supplements, baby aspirin, omeprazole, and lisinopril. Her surgical history was remarkable only for remote tonsillectomy and hysterectomy.

Her physical examination was largely unremarkable, although some course breath sounds were detected over the medial right base. Her vital signs showed normal pulse rate and blood pressure, breathing at 12 breaths / minute. Her room air oxygen saturation was 97%.

Frontal chest radiography (Figure 1) was performed.

Figure 1. Initial frontal chest x-ray.

Which of the following represents the most accurate assessment of the chest radiographic findings? (Click on the correct answer to be directed to the second of sixteen pages)

  1. Chest radiography shows a vague solitary pulmonary opacity
  2. Chest radiography shows basilar fibrotic opacities
  3. Chest radiography shows cavitary pulmonary lesions
  4. Chest radiography shows marked cardiomegaly
  5. Chest radiography shows numerous small nodular opacities
