We report the case of a 95-year-old man with a previous history of myocardial infarction, pulmonary oedema, and hypertension who developed recurrent collapse while undergoing ambulatory urological follow-up for a six-week history of macroscopic haematuria. Following a recent outpatient review, he had received oral antibiotics for a presumed urinary tract infection (UTI). Throughout this six-week ambulatory period, no full blood count or other blood tests were performed, leaving the extent of blood loss and its haematological consequences clinically occult. The patient subsequently experienced three episodes of sudden collapse within one week at home. The episodes were preceded by a prodrome of marked weakness. On assessment by ambulance clinicians, a profound postural blood-pressure drop was identified. Given the postural component and presumed recent urinary infection, dehydration was considered the initial explanation, and intravenous fluid resuscitation was commenced. However, hospital point-of-care investigations substantially changed the diagnostic picture. Venous blood gas analysis demonstrated a haemoglobin concentration consistent with profound anaemia. ECG demonstrated a r

Case: In a patient diagnosed with metastatic clear cell RCC, foci observed at very low levels on 18F-FDG PET/CT, and some that were not detectable at all, were seen as dramatically dense on [68Ga]Ga-DPI-4452-PET/CT (carbonic anhydrase IX receptor) imaging. Image courtesy of Prof. Arslan Research was presented at the 39th Annual Congress of the European Association of Nuclear Medicine (EANM’26)
