99mTc-sulfur colloid scan can be used to confirm the leak and nature of the effusion fluid. Here, we present an 8-year-old girl with recurrent pleural and pericardial effusions after lymphocele excision and total pericardiectomy. 99mTc-sulfur colloid lymphoscintigraphy was done to rule out secondary chylopericardium.
We report the case of a 55-year-old man presenting pseudopsychiatric behavior disorders of subacute-onset. MRI showed a FLAIR (fluid-attenuated inversion recovery) hyperintensity in the left hippocampus. The diagnosis of limbic encephalitis was raised, and the patient was referred for an 18F-FDG PET/CT. PET/CT depicted an increased uptake of the left mesiotemporal structures and also an increased uptake of both cerebellum and striatal areas. This pattern was compatible with an anti-leucine-rich glioma-inactivated 1 antibody encephalitis that was later confirmed.

Metastases of mesenchymal chondrosarcoma to either the pancreas or the adrenal glands are rare. We hereby presented the 18F-FDG PET/CT images of a 21-year-old man initially diagnosed with chondrosarcoma of the right 11th rib. His 18F-FDG PET/CT scan after radiotherapy demonstrated 2 hypermetabolic lesions in the right adrenal gland and the pancreas, respectively. These 2 lesions were later confirmed by biopsy to be metastatic mesenchymal chondrosarcoma.

A 68-year-old man underwent 18F-prostate-specific membrane antigen (PSMA) PET/CT for staging of a newly diagnosed prostate adenocarcinoma. Unexpectedly, PET/CT revealed high focal 18F-PSMA brain uptake, which initially was suspected for a brain metastasis. Corresponding CT and MRI scans revealed characteristic imaging features of an intracranial dermoid cyst at this site. This is an exceptional location for a dermoid cyst, which had been followed up conservatively with no substantial changes. This case shows that dermoid cyst should be added to the reported list of benign neoplasms that shows "false-positive" PSMA uptake during evaluation of patients with prostate carcinoma, representing a potential interpretative pitfall.

Prostate-specific membrane antigen (PSMA) is expressed in the tumor-associated endothelial neovasculature of various nonprostatic benign and malignant neoplasms. A 25-year-old man with recurrent sinonasal glomangiopericytoma underwent whole-body 68Ga PSMA PET/CT to explore its theranostic role. https://www.selleckchem.com/products/sn-001.html There was intense PSMA uptake (SUVmax = 23.9) noted in the tumor. The uptake was more than that of the salivary glands, lacrimal glands, aorta, spleen, and the liver. Performance of PSMA PET/CT in sinonasal glomangiopericytoma opens up new frontiers concerning radiological imaging, early recurrence identification, and perhaps even radioligand therapy of residual/recurrent tumors.

A 58-year-old man with progressive dyspnea and recurrent extensive left-sided pleural effusion underwent pulmonary ventilation/perfusion SPECT/CT, which showed a pronounced mismatched perfusion deficit of the entire, normally ventilated left lung. As unilateral perfusion deficits of an entire lobe are generally not due to pulmonary embolism, further CT angiography and cardiac MRI were conducted. These examinations revealed high-grade left pulmonary vein stenosis (PVS) caused by pulmonary vein isolation performed for atrial fibrillation 3 and 4 years earlier. Thus, in addition to, for example, neoplastic processes or pulmonary congenital vascular abnormalities, PVS must be considered as a differential diagnosis and possible pitfall in ventilation/perfusion SPECT/CT in dyspneic patients with prior pulmonary vein isolation.
