A case of VEXAS (vacuoles, E1 enzyme, X-linked, autoinflammatory, somatic) syndrome presenting as progressive multisystem involvement with parenchymal infiltrates following infection with Epstein Barr virus.

VEXAS (vacuoles, E1 enzyme, X-linked, autoinflammatory, and somatic) syndrome is a rare multisystem disease affecting predominantly males over 50 and manifesting as widespread progressive inflammatory sequelae and haematological dysfunction. We describe a patient who presented with systemic symptoms of fevers, night sweats and weight loss, and developed progressive inflammatory sequelae including cutaneous lesions, haematological dysfunction, lymphadenopathy, migratory inflammatory arthropathies, with new pulmonary infiltrates, following infection with Epstein Barr Virus. Laboratory investigations, bronchoscopy, bone marrow biopsy and imaging were consistent with an inflammatory aetiology.

Unravelling diagnostic challenges: A case report of pulmonary langerhans cell histiocytosis with atypical radiologic presentation.

This clinical case highlights the diagnostic challenges encountered in a young adult smoker presenting with undifferentiated pulmonary nodules. Initial investigations were inconclusive, necessitating surgical lung biopsy due to the nodules' size and location. The histopathological examination revealed pulmonary Langerhans cell histiocytosis (PLCH).

A case of severe pneumonia.

is a thermotolerant nontuberculous mycobacterium which can rarely result in human infection. Although immunosuppression has been identified as a risk factor for infection, it is possible that mycobacterial laboratories may have previously under-recognized as standard mycobacterial incubation temperatures are suboptimal for culture of this organism. Here, we present a case of severe pneumonia associated with achalasia requiring life support in the intensive care unit.

Rare case of cystic anterior mediastinal tuberculosis in an immunocompetent patient.

We report a case of a 28-year-old immunocompetent woman found to have a mediastinal lesion on chest x-ray performed as part of a visa renewal process. Computed tomographic imaging revealed a cystic superior anterior mediastinal mass. Although initially asymptomatic, the woman subsequently developed progressive chest discomfort.

A rare case of common variable immunodeficiency and hepatopulmonary syndrome.

Hepatopulmonary syndrome (HPS) is the triad of liver disease, hypoxia and intrapulmonary shunt. In this case report, we describe an immunocompromised female with a background of common variable immunodeficiency (CVID) who presented with haemoptysis and dyspnoea. Investigations demonstrated significant hypoxaemia and intrapulmonary right-to-left shunting.

A curious case of asphyxiating thoracic dystrophy in an adult.

Asphyxiating thoracic dystrophy (ATD), also known as Jeune syndrome, is a rare autosomal recessive chondrodysplasia that most commonly manifests as shortening of long bones and ribs, as well as frequent extra-skeletal organ involvement. It is typically diagnosed in infancy or early childhood following episodes of respiratory distress or failure, in conjunction with characteristic physical findings, and is often fatal. The genetic heterogeneity of this disease, however, means there is varying severity of symptoms and physical manifestations.

Invasive tracheal aspergillosis after chemoradiotherapy treatment.

Invasive tracheobronchial aspergillosis is a rare disease with most reported cases in the literature occurring in immunocompromised hosts. We report an unusual case of a patient with persistent cough and dyspnoea in the context of prior chemoradiotherapy for primary lung cancer. Chest computed tomography (CT) demonstrated an abnormal soft tissue mass surrounding the trachea and carina, with focal moderate fluorodeoxyglucose (FDG) activity on positron emission tomography (PET) scan.

Tracheobronchial calcification on bronchoscopy in a patient with end stage renal failure: an unusual cause of chronic cough.

Pulmonary calcification can develop as a complication of end-stage renal failure. Most patients are asymptomatic, with characteristic parenchymal changes incidentally detected on computed tomography (CT) imaging and a clinical course that is usually benign. In this report, we describe a 64-year-old female with a history of inadequate peritoneal dialysis who presented with severe chronic cough, a symptom that persisted despite treatment for respiratory tract infection.

Persistent air leak successfully treated with endobronchial valves and digital drainage system.

A 62-year old man with severe chronic obstructive pulmonary disease developed a persistent air leak from an iatrogenic pneumothorax following Computed Tomography-guided core biopsy of a pulmonary nodule. The pneumothorax was treated with an 8.5F intercostal catheter, which was then replaced by a 28F thoracostomy tube after development of significant subcutaneous emphysema and a tension pneumothorax.
