A 48-year-old man presented with 6months of progressive shortness of breath, intermittent exertional left-sided chest pain, and bilateral lower extremity edema. During the 2days before admission, he experienced new onset confusion, fatigue, and malaise that prompted evaluation. He denied fever, chills, cough, or sputum production. He used anabolic steroids for 20 years as part of his bodybuilding hobby. Recently, he also began injecting mineral oil into his pectoral, bicep, and shoulder muscles for an improved muscular appearance.

He had no recent travel, sick contacts, or animal exposures.A 61-year-old woman, an ex-smoker with a 10 pack year smoking history, was referred to our clinic for the evaluation of insidious dyspnea and diffuse, bilateral infiltrates on a chest radiograph. She reported that she had been experiencing dyspnea on exertion and dry cough for the past 1.5 years. She denied fevers, chills, hemoptysis, or weight loss. Aside from a smoking history, there were no comorbidities or environmental exposures. She had no family history of lung diseases or other disorders. She worked as a school teacher and had no occupational exposures. There were no pets in the home and no prior occupational exposures.

A 29-year-old woman who is a never smoker and has a medical history of systemic hypertension presented with a 3-week history of generalized fatigue and dry cough. She endorsed sicca symptoms of dry eyes and dry mouth. She denied breathlessness, fever, chills, night sweats, or weight loss. She had no heartburn, postnasal drip, joint pain, swelling, or skin lesions. She had no known lung disease or history of pneumothorax. Her family history was unremarkable.

A 57-year-old man who had been intubated and placed on venovenous extracorporeal membrane oxygenation for hypoxemic respiratory failure due to COVID-19 pneumonia was transferred to our facility. He underwent anticoagulation with IV heparin titrated to an anti-Factor Xa goal of 0.1 to 0.3 international unit/mL. CGS 21680 cost Over extracorporeal membrane oxygenation days 13 to 17, his WBC count rose from 17,500 to 47,000 cells/μL. He simultaneously experienced the development of fluid-refractory shock that required multiple vasopressors and received stress-dose hydrocortisone when his WBC was 30,000 cells/μL. He remained afebrile and was started on broad-spectrum antimicrobials that included antifungal and anthelminthic therapy.

A 58-year-old man presented to the ED with a 1-week history of progressive weight loss, generalized weakness, unsteadiness, and dizziness. In hospital, he experienced a witnessed episode of loss of consciousness with no observable respirations that lasted for 15 minutes. Hisarterial blood gas demonstrated hypercapnic respiratory failure, and he required mask ventilation and vasoactive medications. Similar episodes occurred several more times over the course of the night that required the patient to be intubated. The paroxysmal episodes persisted necessitating continued invasive ventilatory support and admission to the ICU. The episodes occurred in both awake and asleep states and required the ventilator settings to dictate a minimum rate, but minimal ventilatory support otherwise. Further history revealed other symptomatic complaints of vertigo, dysphagia, and hypophonia that had progressed over a 2-month period. The patient's medical history was pertinent for a diagnosis of prostatic carcinoma 3 years prev Further history revealed other symptomatic complaints of vertigo, dysphagia, and hypophonia that had progressed over a 2-month period. The patient's medical history was pertinent for a diagnosis of prostatic carcinoma 3 years previously that was found to be castrate resistant. He had metastases to his hip, ribs, and thoracic spine. Previous treatments had included bicalutamide, docetaxel, and abiraterone; he was receiving leuprolide therapy on presentation.A 61-year-old man presented to the ED with fever, chills, cough, purulent sputum, and progressive shortness of breath for 7 days. link2 The patient was an active smoker with at least 80 pack-year smoking history. He had no other medical or surgical history and was not on any medication at home.

A 66-year-old woman with a history of diabetes presented with an intermittent low-grade fever, cough, shortness of breath, and decreased activity tolerance over a 3-month period. She is a farmer, and denied a history of chronic pulmonary disease. link3 Her only medical history was type 2 diabetes managed without medication. She denied smoking or tobacco use. She did not report any recent travel and denied having birds at home. Imaging at a local hospital showed left lower lobe atelectasis with a small pleural effusion. An infection with mucormycosis was diagnosed through transbronchial biopsy. The patient was given nebulized amphotericin B along with concurrent IV liposomal amphotericin B for a total of 15days. She experienced no significant improvement in symptoms during therapy and, in fact, developed worsening, progressive dyspnea.

Respiratory complications are described in less then 50 cases in the literature,1 without prior report of lung transplantation (LT). This article explains the clinical course of the first patient to receive LT for pulmonary SS and presents evidence suggesting recurrence of the primary lung disease in the allograft.Pulmonary amyloidosis, whether isolated or seen as part of systemic amyloidosis, has a variety of radiographic manifestations. Known parenchymal lung findings include reticulonodular opacities, diffuse interstitial infiltrates, or cystic lesions. Here, we present a case of systemic amyloid light-chain (AL) amyloidosis presenting with severe exertional dyspnea and emphysematous lung lesions on chest CT, a finding described only once before. Although factors that influence the pattern of pulmonary amyloid deposition remain unclear, CT image findings typically reflect the histopathologic patterns of deposition. In this case, we hypothesize that the emphysematous changes in the lower lung zones are likely a manifestation of severe alveolar-septal involvement. This case suggests that radiographic findings of pulmonary amyloidosis are not limited to the more common findings of reticular opacities or interstitial infiltrates. Emphysematous changes are possible, and clinicians should maintain a broad differential when seen in the setting of dyspnea.
