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, Critical Care & Sleep 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.

April 2024 Medical Image of the Month: Wind Instruments Player Exhibiting Exceptional Pulmonary Function

Figure 2.  Pulmonary function testing results demonstrating exceptional pulmonary function

 

A 64-year-old man was referred to our pulmonary clinic for evaluation of his pulmonary status.  He had a 7-year history of rheumatoid arthritis and was treated initially with steroids and subsequently maintained on methotrexate and monthly adalimumab injections. The patient reported that his rheumatoid arthritis symptoms were controlled.  He experienced no joint pain or morning stiffness at the time of evaluation. From a pulmonary perspective, he denied respiratory symptoms such as exertional shortness of breath, cough, wheezing, or chest tightness.  He reported no limitations in physical activities. The patient has an occupational history of 45-years as a welder, with exposure to dust, metal fumes, benzene, and sulfur gas. The patient also has a 15 pack-year smoking history but quit 35 years ago.

A high-resolution chest CT (Figure 1) ordered by his rheumatologist showed normal lung parenchyma. The first pulmonary function test (PFT), conducted on the initial pulmonary clinic visit, revealed lung volumes significantly higher than the reference range. This is despite the patient’s occupational history, smoking history, and the fact that he is currently on methotrexate and adalimumab therapy. The patient remained asymptomatic from a pulmonary standpoint on annual checkups. Three years later, a repeat PFT (Figure-2) demonstrated similar results.  Further history revealed that the patient had regularly used wind instruments, including the saxophone and harmonica, since high school. Initially, he played at irregular intervals, but for the last 15 years, he consistently practiced 1-2 hours daily and performed weekly at local venues.

Several studies have investigated the pulmonary effects of wind instrument playing, offering insights into the relationship between musical activities and respiratory function. Fiz et al. (1) found that maximum respiratory pressures were elevated in trumpet players.  Munn et al. (2) reported on the pulmonary function of commercial glass blowers [2]. Barbenel et al. (3) explored mouthpiece forces during trumpet playing and Kahane et al. (4) evaluated the upper airway and larynx in professional bassoon players. Cossette et al. (5) examined chest wall dynamics during flute playing. Schorr-Lesnick et al. (6) studied pulmonary function in singers and wind-instrument players [6], and Navratil et al. (7) assessed lung function in wind instrument players and glass blowers. Borgia et al. (8) provided physiological observations on French horn musicians. While existing studies present conflicting findings on the impact of wind instrument playing on respiratory function, our case adds to the growing body of evidence suggesting a potential positive correlation between long-term wind instrument training and enhanced respiratory muscle strength.

This observation prompts further exploration and investigation into the field of pulmonary rehabilitation with the hope of uncovering therapeutic benefits for individuals with chronic pulmonary conditions.

March 2024 Medical Image of the Month: Sputum Cytology in Patients with Suspected Lung Malignancy Presenting with Acute Hypoxic Respiratory Failure

Figure 1. Axial image from a CT scan (A) showing masslike consolidation in the right lower lobe (*). Axial image from FDG-PET CT (B) showing the hypermetabolic center of the mass-like consolidation (arrow).

 

Figure 2. Sputum cytology low power (A) and high power (B) H&E stains showing clusters of malignant cells.

 

A 71-year-old woman presented with right-sided mass-like consolidation and pleural effusion on CT (Figure 1A), discovered incidentally after placement of a drug-eluting stent for coronary artery disease. The patient had a medical history significant for COPD, hypertension, hyperlipidemia, and coronary artery disease, status post a recent drug-eluting stent (less than 1 month ago). The patient received a presumptive diagnosis of pneumonia with parapneumonic effusion. Findings persisted despite multiple courses of empiric antibiotic therapy. She then underwent thoracentesis; pleural fluid was exudative; however, cytology was inconclusive. An FDG PET-CT (Figure 1B) revealed hypermetabolic activity in the right lower lobe with radiotracer activity up to 7.7 SUV concerning for malignancy. Diagnostic bronchoscopy was planned; however, her condition deteriorated suddenly the day before her planned procedure. EMS found the patient to be severely hypoxic, SpO2 in the 70s. Patient was taken by ambulance to the local emergency room.

Upon arrival, the patient was in mild respiratory distress which improved upon applying non-invasive positive-pressure ventilation. She had mild tachycardia and reduced air movement in the right lower third of the chest on physical exam. Repeat CT confirmed the persistence of the right lower lobe mass-like consolidation and moderate-sized pleural effusion. Empirical treatment for post-obstructive pneumonia was initiated. Right-sided thoracentesis again demonstrated exudative pleural fluid with negative cytology for malignancy and negative culture results. Due to concerns about her respiratory status, diagnostic bronchoscopy was abandoned. However, the patient was coughing up blood-tinged sputum which was sent for cytology (Figure 2) confirming a diagnosis of non-small cell lung cancer favoring adenocarcinoma. Immunostains performed on sections of the cell block showed malignant cells positive for CK7 and TTF1 and negative for P40 supporting the diagnosis of adenocarcinoma of lung.

This case emphasizes the importance of utilizing noninvasive testing like sputum cytology in patients with severe morbidity to help uncover underlying diagnoses. Studies and medical case reports highlighted the significance of sputum analysis in diagnosing lung cancer (1,2). Challenges posed by this case underscore the importance of considering alternative noninvasive measures to aid in making accurate diagnosis and help patient's and family understanding the underlying etiology of her persistent pneumonia )overall prognosis.
