We report an infant with respiratory instability after PAB who underwent computational fluid dynamics (CFD) as an adjunctive functional assessment. After extubation, recurrent intercostal retractions and oxygen desaturation occurred during crying. Contrast-enhanced CT and bronchoscopy revealed mild-to-moderate tracheobronchial narrowing caused by dilated pulmonary arteries without intrinsic obstruction. A patient-specific CFD model simulated inspiratory airflow at 100 mL/s, approximating crying. Total airway resistance was markedly elevated (15 Pa/mL/s vs. approximately 0.07 Pa/mL/s in healthy infants), with pronounced airflow asymmetry and reduced flow to the right main bronchus, suggesting functional impairment despite relatively preserved airway lumens. These findings were considered complementary to the overall clinical assessment, rather than an independent surgical indication. The patient's symptoms resolved after pulmonary artery plication and ventricular septal defect closure.","PeriodicalId":45846,"journal":{"name":"Respirology Case Reports","volume":"14 9","pages":"e70749"},"PeriodicalIF":0.7,"publicationDate":"2026-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13531353/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148876092","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We report an adult patient with underlying ILD who developed acute respiratory deterioration in the setting of primary parvovirus B19 infection. A 70-year-old Japanese man was admitted to our department with a low-grade fever and a facial rash. Two years prior to admission, the patient had been diagnosed with ILD, which had been treated with systemic corticosteroids that were subsequently discontinued following clinical improvement. High-resolution computed tomography (HRCT) revealed newly developed bilateral ground-glass opacities. Infection with parvovirus B19 was confirmed by serological testing and bronchoalveolar lavage results. Although the precise contribution of parvovirus B19-associated lung injury, infection-triggered AE-ILD and acute exacerbation of the underlying ILD could not be definitively determined, steroid pulse therapy led to clinical and radiological improvement. This case highlights the importance of considering parvovirus B19 infection as a potential contributor to acute respiratory deterioration in patients with underlying ILD.","PeriodicalId":45846,"journal":{"name":"Respirology Case Reports","volume":"14 9","pages":"e70751"},"PeriodicalIF":0.7,"publicationDate":"2026-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13531226/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148876108","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We report the case of an adolescent male who developed NPPE with features of concurrent negative pressure pulmonary haemorrhage (NPPH) following approximately 90 s of neck compression. He experienced transient loss of consciousness with hypoxic myoclonic activity, followed by haemoptysis and hypoxia requiring supplemental oxygen. Chest X-ray (CXR) revealed bilateral opacities, which was followed up by computed tomography (CT) of the chest demonstrating diffuse bilateral ground-glass and confluent opacities consistent with pulmonary oedema and probable superimposed haemorrhage. He recovered with supplemental oxygen alone within 48 h. This case shows that even brief neck compression can cause significant pulmonary injury, that chokeholds are an under-recognised precipitant, and that concurrent NPPH may mimic aspiration or infection, risking unnecessary intervention.","PeriodicalId":45846,"journal":{"name":"Respirology Case Reports","volume":"14 9","pages":"e70740"},"PeriodicalIF":0.7,"publicationDate":"2026-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13531352/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148876097","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A 70-year-old man with a history of gastric cancer presented with mediastinal lymphadenopathy and a nodule in the right upper lobe. EBUS-TBNA confirmed SCLC in the mediastinal lymph nodes. For the peripheral pulmonary lesion, BDBD enabled further advancement of the thin bronchoscope, allowing direct visualization and biopsy with standard forceps, which confirmed NSCLC. No procedure-related complications occurred. This case suggests that combining EBUS-TBNA with BDBD facilitates the accurate diagnosis of multiple pulmonary lesions during the same bronchoscopic session.","PeriodicalId":45846,"journal":{"name":"Respirology Case Reports","volume":"14 9","pages":"e70743"},"PeriodicalIF":0.7,"publicationDate":"2026-08-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13525331/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148857619","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Following chest tube reinsertion and complete lung re-expansion, chemical pleurodesis was performed using 1000 mg doxycycline in saline. Transient pleuritic pain was controlled with intravenous ketorolac and intrapleural lidocaine. No other immediate or delayed adverse events occurred. In parallel, pulmonary rehabilitation, including breathing exercises, posture correction, moderate-intensity endurance and inspiratory muscle training, was initiated alongside nutritional repletion with a respiratory-specific oral nutritional supplement. Over a 22-month follow-up, the patient remained free of SSP recurrence, with improved functional capacity and weight gain.
