Pericardial sarcoma: “invisible” on radiology

We report the case of a 17-year-old patient with recurrent hemorrhagic pericardial effusion, who was diagnosed with primary pericardial fibrosarcoma. However, multiple radiological examinations, including CT and [18F] FDG/PET-CT, suggested the presence of fluid and no sign of tumor. Actually, when a patient presents with recurrent hemorrhagic pericardial effusions, pericardial tumors must be taken into account as part of the differential diagnosis.

Abstract This research concerned radioactivity of lichens and mosses from coastal zones of the Canadian Arctic and Alaska. Over 50 samples were collected from 7 positions during two scientific expeditions in 2012 and 2013. The tundra contamination caused by anthropogenic radionuclides was relatively low, reaching mean values with SD's of: 17.4 ± 3.5 Bq/kg for 90Sr, 14.0 ± 2.9 Bq/kg for 134Cs, 38.4 ± 7.5 Bq/kg for 137Cs, 0.86 ± 0.24 Bq/kg for 239+240Pu, 0.065 ± 0.017 Bq/kg for 238Pu and 0.50 ± 0.13 Bq/kg for 241Am. The increase of activity concentrat...

Authors: Dib J Abstract I read with great interest the paper by Sousa M. Tumor seeding of the fistula tract should be suspected in patients with a previous history of esophageal or nasopharynx squamous cell carcinoma who have undergone a Percutaneous Endoscopic Gastrostomy (PEG) with a persistent gastrocutaneous fistula. Especially after the use of an OTSC. In fact, the "pull technique" for PEG tube placement should not be used in this context. PMID: 31729232 [PubMed - as supplied by publisher]

We examined US sensitivity for diagnosis of HCC in obese patients. Methods: Liver transplant patients data with HCC in explant was used (January 2012-December 2017). All patients underwent liver US within 3 months of diagnosis of HCC. Number/size of HCC lesions were extracted from radiologic and pathologic reports. Obesity was defined as BMI ≥30 kg/m2. Results: One hundred sixteen patients were included. 80% were male, with mean BMI of 31 kg/m2. The most common underlying liver disease was hepatitis C virus (62%). At the time of diagnosis, median number of HCC lesions was 2 (interquartile range [IQR], 1-3), and ...

ConclusionsFontan patients commonly have chronotropic incompetence, diminished heart rate reserve but with preserved heart rate recovery. While there is overall no difference in chronotropy in Fontan patients based on dominant systemic ventricle, there is a difference between HLHS and tricuspid atresia patients.

We describe the case of a 43-year-old patient who presented with a transient ischemic attack episode, desaturation and ventricular arrhythmias. Transesophageal echocardiography diagnosed a PFO, whilst magnetic resonance imaging revealed two small myocardial infarcts, despite normal coronaries on subsequent angiography. Echocardiography and cardiac CT revealed a LACV with bidirectional flow. The patient underwent percutaneous LACV and PFO closure, with immediate saturation increase following occlusion of the LACV. To the best of our knowledge, this is the first time a LACV is identified as the cause of recurrent thromboembolic events.
