AbstractThe aim of our study is a retrospective evaluation of effectiveness and safety of Computed Tomography (CT)-guided radiofrequency ablation (RFA) therapy of primary and metastatic lung lesions in patients that cannot be considered surgical candidates. From February 2007 to September 2017, we performed 264 CT-guided ablation sessions on 264 lesions in 174 patients (112  M and 62 F; mean age, 68 years; range 36–83 years) affected by primary and metastatic lung lesions. The 45% of patients was affected by primary lung cancer, with size range lesion of 10–50 mm, and the 55% by metastatic l...

AbstractThe purpose of this study was to evaluate the added value of postmortem magnetic resonance imaging (MRI) compared to postmortem computed tomography (CT) and autopsy in cases of fatal hanging. In addition, the study analyzed the strengths of each examination method regarding typical injuries in these cases. We investigated a cohort of 25 decedents who underwent CT, MRI and autopsy. Two radiologists assessed all MR images of the head and neck as well as the corresponding CT images. The results were compared to autopsy findings by retrospectively analyzing the autopsy reports. Postmortem MRI revealed intramuscular hem...

We report a case where serial follow-up chest computed tomography revealed progression of pulmonary lesions into confluent bilateral consolidation with lower lung predominance, thereby confirming COVID-19 pneumonia. Furthermore, complications such as mediastinal emphysema, giant bulla, and pneumothorax were also observed during the course of the disease. PMID: 32207255 [PubMed - as supplied by publisher]

We present the case of a 22-year-old male who presented to us with abdomen discomfort with subcutaneous emphysema in the abdomen and lower chest, following a prank played by his friend who had inserted a nozzle through his anal orifice and pumped high-pressure condensed air through it. Computed tomography showed evidence of air pockets in the ischiorectal fossa and pelvis. Intraoperatively, we found large-bowel and small-bowel distension with large-bowel serosal tears and rectal tears. The tears were primarily sutured and a transverse loop colostomy was fashioned to facilitate healing of rectal wounds and to relieve the di...

AbstractProgressive connective tissue disease (CTD)-related lung disease is a challenging condition that requires lung transplantation in some patients. Treatment with rituximab may improve lung function. To evaluate the effect of rituximab in patients with progressive CTD-related lung disease who met criteria for inclusion in waiting list for a lung transplant. Retrospective study of patients with progressive CTD-related lung disease with criteria for lung transplant (FVC

Conclusion: Combining forensic imaging and endoscopic autopsy for postmortem examination yields a more comprehensive and scientific finding, and the combination is minimally invasive and more acceptable to the family members. This method can be used as an alternative for conventional autopsy under specific circumstances.

ConclusionPneumorrachis is usually asymptomatic and is self-limiting. It is a radiological diagnosis and is not a clinical diagnosis. CT scan is considered the preferred diagnostic method for reliable and rapid detection of pneumorrachis. In case of coexistence, The physician should be alert to diagnose and treat the underlying cause for related injuries.In such cases, successful results can be obtained with hyper-oxy therapy (100% oxygen inhalation) and antibiotic prophylaxis without the need for surgical treatment.

ConclusionNon-emphysematous gas trapping in the upper and lower lobes has a distinct physiological effect, especially in COPD with minimal emphysema. This local evaluation might allow sensitive detection of changes in lung hyperinflation in COPD.

ConclusionRadiological findings of particular interest included the high burden of opacities observed and the presence of RCS ‐associated features in the majority of subjects. Radiologists are at the front line in occupational lung disease screening/diagnosis and must be aware of the imaging spectrum.

Publication date: Available online 9 February 2020Source: Respiratory Medicine Case ReportsAuthor(s): Nina Järvelä Johansen, Ole Hilberg, Anders LøkkeAbstractA 50-year-old former smoker presented with recurrent pneumonia, fever and atypical chest pain on and off for a year and was treated with antibiotics several times. Meanwhile, her lung function deteriorated with an obstructive pattern and therefore she was treated with inhalation medication without effect. Tests of the heart, bronchoscopy, gastroscopy and a CT-scan of the lungs did not reveal the cause. Finally, an FDG-PET scan showed inflammation of t...
