Authors: Guo L, Chen B, Zhang L, Deng Y, Li H, Shi QD Abstract A 49-year-old female patient developed chest tightness and shortness of breath without apparent cause and presented to a local hospital. Chest radiography indicated increased thickening of the lung texture, increased multiple patchy densities in the lower lobes of the bilateral lungs and a slightly enlarged thyroid. The patient was treated for pulmonary infection with antibiotics but the symptoms persisted. A repeated CT scan revealed ground-glass attenuation of the bilateral lungs with multiple flaky exudates and visible bronchogenic signs. The symptom...

Conclusion: Follow up CXRs can lead to new malignant and non-malignant diagnosis both when the radiological changes are persistent and when only partially resolved. Further work is required to risk stratify patients into higher and lower risk groups.

CONCLUSIONS: PJP on CT differs substantially between RTRs and HIV-positive patients. Physicians should be aware of such differences in order not to delay treatment, particularly in renal transplant recipients. PMID: 31580472 [PubMed - in process]

Focal cryptogenic organizing pneumonia can be diagnosed with computed tomography ‐guided biopsy, avoiding surgical resection and can be treated with oral corticosteroids. Early treatment can reduce relapses and is cost‐effective. Focal cryptogenic organizing pneumonia (FOP) is a localized form of cryptogenic organizing pneumonia (COP). It is an uncommon clinicopathological entity associated with non ‐specific symptoms and radiographic findings simulating lung malignancy. Incidence of idiopathic FOP is not known and only reported as case series. Its treatment usually involved surgical resection. Here, we report a case...

We present a case of cavernous hemangioma classified as venous malformation of the lung in an infant, which was initially diagnosed and treated as pneumonia. The patient was a 9-month-old boy with a history of cavernous hemangioma on the right sole of the foot that was treated with resection at 8 months of age. He presented with the symptoms of upper respiratory inflammation of 2 weeks' duration. A localized mass was found in the lower right lung field on chest radiography, and a 5-cm tumorous lesion was detected on computed tomography. Although there were no imaging findings suggesting malignancy, a malignant disease coul...

Conclusion: Hybrid SPECT/CT (Q) imaging has a high diagnostic accuracy for detecting PTE than planar (Q) scans interpreted with chest radiographs. In addition, low dose CT used in SPECT/CT was able to identify other non-embolic pathologies (eg: pneumonia, emphysematous bullae, tumor or lymphadenopathy) responsible for perfusion defects which could have been missed on chest radiography thereby increasing the specificity. Modified PIOPED II had a higher number of non-diagnostic results compared to PISAPED which increases the latter's clinical utility.

CONCLUSION Among elderly fall patients, CT-identified rib fractures were associated with increased hospital admissions. However, there was no difference in procedural interventions, ICU admission, hospital/ICU LOS or mortality for patients with and without radiographically occult fractures. LEVEL OF EVIDENCE Diagnostic, level III.

The use rate of donor lungs in lung transplantation has always been lower than the rates associated with other organs. Currently, we transplant less than 20% of lungs initially offered.1,2 The lungs are the only organ with direct exposure to the outside environment; as such, they are acutely vulnerable to pneumonia, atelectasis, contusion, and aspiration. Historically, we have assessed the quality of donor lungs based on donor characteristics (eg, age, lifestyle), radiographic imaging (chest radiograph and computed tomography), and organ function (partial pressure of oxygen on 100% oxygen, or P/F ratio).
