Infective endocarditis is a common and treatable condition that carries a high mortality rate. Currently the workup of infective endocarditis relies on the integration of clinical, microbiological and echocardiographic data through the use of the modified Duke criteria (MDC). However, in cases of prosthetic valve endocarditis (PVE) echocardiography can be normal or non-diagnostic in a high proportion of cases leading to decreased sensitivity for the MDC. Evolving multimodality imaging techniques including leukocyte scintigraphy (white blood cell imaging), F-fluorodeoxyglucose positron emission tomography (FDG-PET), multidetector computed tomographic angiography (MDCTA), and cardiac magnetic resonance imaging (CMRI) may each augment the standard workup of PVE and increase diagnostic accuracy. While further studies are necessary to clarify the ideal role for each of these imaging techniques, nevertheless, these modalities hold promise in determining the diagnosis, prognosis, and care of PVE. We start by presenting a clinical vignette, then evidence supporting various modality strategies, balanced by limitations, and review of formal guidelines, when available. The article ends with the authors' summary of future directions and case conclusion.

F-Prostate-Specific Membrane Antigen PET/CT imaging for potentially resectable pancreatic cancer (PANSCAN-2): a phase I/II study.

Background: Current diagnostic imaging modalities have limited ability to differentiate between malignant and benign pancreaticobiliary disease, and lack accuracy in detecting lymph node metastases. F-Prostate-Specific Membrane Antigen (PSMA) PET/CT is an imaging modality used for staging of prostate cancer, but has incidentally also identified PSMA-avid pancreatic lesions, histologically characterized as pancreatic ductal adenocarcinoma (PDAC). This phase I/II study aimed to assess the feasibility of F-PSMA PET/CT to detect PDAC.

Background And Purpose: Prolonged venous transit (PVT), derived from computed tomography perfusion (CTP) time-to-maximum (T) maps, reflects compromised venous outflow (VO) in acute ischemic stroke due to large vessel occlusion (AIS-LVO). Poor VO is associated with worse clinical outcomes, but pre-treatment markers predictive of PVT are not well described.
Methods: We conducted a retrospective analysis of 189 patients with anterior circulation AIS-LVO who underwent baseline CT evaluation, including non-contrast CT, CT angiography, and CTP.
Radiofrequency ablation in tumour-induced osteomalacia: a therapeutic challenge.
BMJ Case Rep

Internal Medicine, MS Ramaiah Medical College, Bengaluru, Karnataka, India.
Tumour-induced osteomalacia (TIO) is an uncommon, debilitating disorder often characterised by non-specific clinical manifestations, posing a significant diagnostic challenge. The tumours causing TIO can be minuscule and occur in unusual areas, further complicating diagnosis. This report details the case of a woman in her early 30s presenting with chronic pain who subsequently developed fragility fractures.

We report a rare case of urinary bladder neuroendocrine tumour (NET) in a young, non-smoking man. He had no known risk factors and no comorbidities. After being diagnosed with a bladder tumour while being investigated for flank pain and poor renal function, he was treated with transurethral resection of the bladder tumour and deroofing of ureters bilaterally.

A young man presented with complaints of angina on exertion and dyspnoea on exertion for the last 3 months. On evaluation, he was found to have a cystic mass in the left ventricle with severe left ventricular systolic dysfunction. A cardiac MRI revealed a multiloculated mass in the left ventricle with multiple septa with internal enhancement and CT coronary angiography revealed compression of a coronary artery by the cystic mass.
