Identify sarcoid-like reaction in cancer patients receiving chemotherapy and immunotherapy: dont get into the weeds of SUVmax
Conclusions: To avoid pitfall in PET/CT interpretation, it is important to recognize the sarcoid-like pattern of FDG uptake, which regardless of SUV value is favored to represent a benign rather than a malignant process.
ConclusionAbdominal irAEs were detected on CT in 13% of NSCLC patients treated with nivolumab, and colitis, in the pancolitis form, was the most common irAE. Given the expanding role of immunotherapy, radiologists should be aware of the frequency and imaging manifestations of abdominal irAEs and the impact on patient management.
How could a country keep around 1.4 billion people healthy when the system struggles with corruption, lack of resources and an aging population? China, the emerging giant with a strong central leadership fostering technology and innovation, places its bets on artificial intelligence, telemedicine, cloud-based hospitals, and WeChat. While that could sound like an ultimate technological paradise, the question is, what are they going to do with the vast amount of data or to what interests are they going to leverage their state of the art A.I. systems? Generally, how will we speak about digital health in China: a healthcare dy...

We describe a 16-year-old high school student referred for management of achalasia who turned out to have pseudoachalasia due to adenocarcinoma of the cardia. He was cured with preoperative chemotherapy followed by radical surgery. Therapy of pseudoachalasia secondary to neoplasia is directed against the tumor or may be palliative to keep the lumen open. Other causes of pseudoachalasia include esophageal motility disturbances as a paraneoplastic phenomenon (e.g., with small cell lung cancer), post fundoplication or post bariatric surgery, in association with a thoracic aortic aneurysm, or with sarcoidosis or amyloidosis. T...
ConclusionBased on our findings, 10% patients in the interim or late PET/CT showed ‘sarcoid-like lymphadenopathy’ as response to treatment. All these patients showed disease control, implying a relation between the appearance of sarcoid-like lymphadenopathy and the clinical benefit of anti-CTLA-4 therapy. On the other hand, quantitative18F-FDG PET analysis of the spleen showed a poor performance in predicting clinical benefit to ipilimumab.
Abstract A 69-year-old woman was diagnosed with sarcoidosis, which was not treated with corticosteroid therapy. Her levels of angiotensin converting enzyme decreased significantly over 4 years and a mass lesion was detected near the lower part of her left main bronchus, and diagnosed as small cell lung cancer (SCLC). Treatment of the SCLC with a series of chemotherapeutic agents produced excellent results. The pulmonary sarcoidosis did not show any deterioration despite the frequent use of amrubicin, which is known to be a cause of interstitial pneumonia. This is a case report of SCLC complicated with sarcoidosis ...
In conclusion, using newer sensitive imaging tool we detected 36 (9.2%) patients with serious pathologies before the first symptoms. Therefore we believe, that ¹F-FDG PET/CT imaging can be recommended to be done not only in all MGUS patients with suspected SMM or active MM, but also for early identification of other serious pathologies.DisclosuresNo relevant conflicts of interest to declare.
Conclusion: The pillars of radiological diagnosis of destructive pulmonary TB are less thickness of the cavity wall, even interior contouring, rounded polygonal form. Non-tuberculous and cancer cavities are characterized by thicker walls, uneven interior contouring, polygonal fissured form.
