RESUMEN
This case describes an uncommon presentation of type 2 respiratory failure secondary to left hemidiaphragmatic paralysis. Emphasis is on the multitude of possible causes of hemidiaphragmatic paralysis and how to manage such a presentation. https://bit.ly/3Mcd2XI.
RESUMEN
A 62-year-old woman presented with a 3-month history of shortness of breath on exertion and dry cough. On examination, she was noted to have fine end-inspiratory crepitations over the upper zone of the lungs. Pulmonary function tests (PFTs) showed a restrictive defect. Initial chest radiography revealed diffuse reticular interstitial shadowing while high-resolution CT scan of the thorax showed fibrotic changes. Avian precipitins were also highly positive for pigeons, parrots and budgerigars. Taking into account these results, the patient was diagnosed with hypersensitivity pneumonitis. Antigen avoidance, oral glucocorticoids and azathioprine achieved an initial improvement in PFTs and symptoms; however, the patient still deteriorated, requiring long-term oxygen therapy. While working the patient up for lung transplantation, rituximab was given to good effect (acting as a bridging therapy) as it achieved symptomatic relief and stabilisation of her PFTs.

The authors report a case of a 58-year-old woman, ex-smoker, who was referred to the respiratory clinic with a presumed unresolving airspace shadowing in the right lung. Further evaluation of the shadowing with a CT thorax revealed rib lesions, a pancreatic lesion and multiple liver lesions, making the diagnosis of metastatic pancreatic carcinoma most likely. However, further blood investigations and imaging eventually revealed the cause for the shadowing to be multiple myeloma, since the unresolving shadowing was actually a rib lesion.

The authors report a case of a 20-year-old woman who was diagnosed with pulmonary cystic echinococcosis. She was admitted to hospital with a 1-week history of unresolving cough, coloured sputum with occasional haemoptysis and fever despite oral antibiotics. Radiology revealed a cavitating right lower lobe lung abscess. After 4 weeks of treatment, follow-up radiology showed incomplete resolution. Bronchoscopy revealed a white, avascular cystic lesion in the right lower lobe and serology testing for Echinococcus granulosus was positive. Repeat imaging eventually confirmed the cystic lesion with the 'air bubble'sign. A thorough travel history, a high index of clinical suspicion and close follow-up are essential in making a diagnosis of pulmonary cystic echinococcosis.

INTRODUCTION: Desmoid tumours are locally aggressive tumours which are common in Familial Adenomatous Polyposis (FAP). PRESENTATION OF CASE: A 20-year old Familial Adenomatous Polyposis (FAP) patient presented with abdominal pain and distention. Abdominal imaging showed small bowel obstruction and hydronephrosis due to a pelvic mass. This mass showed significant enlargement on repeat imaging, and a diagnostic biopsy confirmed desmoid tumour. The mass was deemed unresectable and he was initially started on sulindac and raloxifene. Repeat imaging however showed further enlargement of the tumour, and therefore vinblastine+methotrexate chemotherapy was commenced, with a good response. DISCUSSION: FAP is an autosomal dominant condition caused by a germline mutation in the adenomatous polyposis coli (APC) gene. Gardner's syndrome is also caused by a mutation in the APC gene, and is now considered a different phenotypic presentation of FAP. Desmoid tumours are initially kept under observation while their size remains stable. Treatment options for enlarging desmoids tumours include surgery (first-line), radiotherapy, and systemic therapy with non-cytotoxic and cytotoxic therapy. CONCLUSION: FAP patients should be examined regularly post-panprocotocolectomy, since desmoid tumours may arise. The presence of epidermal cysts in this FAP patient suggests a diagnosis of Gardner's syndrome.
