Bacterial cytoplasmic filters together enhance the antitumor task involving autologous most cancers vaccines.
We report a rare case of pancreatic collision tumor of solid pseudopapillary tumor and neuroendocrine tumor in a 43-year-old woman. A pancreatic mass was found by abdominal ultrasound. A mainly cystic mass with solid component progressive enhancement was revealed using abdominal enhanced CT. Staging 18F-FDG PET/CT demonstrated a pancreatic tail mass with an increased uneven 18F-FDG uptake. Distal pancreatectomy was performed. Postoperatively, the mass was diagnosed as pancreatic collision tumor of solid pseudopapillary tumor and neuroendocrine tumor.

This was the case of a 61-year-old woman with a medical history significant for hypertension and rheumatoid arthritis treated with chloroquine for the last 10 years. She was admitted to our hospital for heart failure symptoms. Echocardiography revealed severe concentric left ventricular hypertrophy. Serum and urine immunofixation electrophoresis and serum light chain assay were negative. No late gadolinium enhancement was observed on cardiovascular magnetic resonance. 99mTc-99mTc-DPD (3,3-diphosphono-1,2-propanodicarboxylic acid) scintigraphy showed myocardial uptake (Perugini score 2/3). Genetic testing excluded hereditary transthyretin cardiac amyloidosis. Endomyocardial biopsy analysis did not show findings suggestive of amyloidosis but consistent with chloroquine toxicity. Chloroquine-mediated cardiotoxicity is rare, and there are very few reports about bone scintigraphy imaging features.

A 75-year-old man presented with dyspnea for more than 2 months, with blood test showing low platelet count and cardiac ultrasound showing severe pulmonary hypertension (>54 mm Hg). A CT pulmonary angiogram showed a filling defect in the pulmonary trunk, right and left pulmonary arteries, raising the possibilities of pulmonary embolism or artery sarcoma. FDG PET/CT was performed for further evaluation and showed low uptake in the pulmonary wall, which supported the diagnosis of pulmonary embolism. Patient was treated with anticoagulants with no changes on repeated CT pulmonary angiogram. Patient underwent surgery, and histopatological examination revealed a pulmonary artery sarcoma.

A 66-year-old man with prostate adenocarcinoma status post radical retropubic prostatectomy and bilateral pelvic lymph node dissection, followed by salvage external beam radiation therapy to the prostate bed 1 year after surgery. Over the course of 17 years, the patient underwent multiple lines of systemic treatment for recurrent disease. He was referred for restaging 18F-fluciclovine PET/CT due to rising serum prostate-specific antigen levels. Contrast-enhanced 18F-fluciclovine PET/CT images demonstrated multiple new liver metastases, which were relatively photopenic in comparison with the physiologic radiotracer activity in the surrounding normal liver parenchyma.

A 64-year-old man with primary progressive multiple sclerosis (Expanded Disability Status Scale 3.5) underwent PET using 18F-PBR06, a second-generation 18-kDa translocator protein ligand targeting activated brain microglia and astrocytes. Voxel-by-voxel statistical comparison of patient's PET images (acquired 60-90 minutes postinjection) with a healthy control data set was performed to generate a 3-dimensional z-score map of increased radiotracer uptake, which showed widespread increased glial activation in normal-appearing cerebral white matter, white matter lesional and perilesional areas, brainstem and cerebellum. In contrast, patient's 3-T MRI scan showed only a few small white matter brain lesions without contrast enhancement.
