Acute hypertensive crisis due to newly diagnosed pheochromocytoma in the ninth decade of life: an unusual presentation

The patient is an 85-year-old man with multiple comorbidities, including hypertension and coronary artery disease with recent myocardial infarction who underwent cardiac catheterisation. During the procedure, the patient developed profound hypertensive crisis with flash pulmonary oedema, requiring significant intervention for blood pressure (BP) control. His crisis was also marked by wide excursions in his BP. The patient was found to have a large left adrenal mass measuring 9.4×8.7×8.1 cm, with biochemical testing confirming the suspicion of pheochromocytoma. Alpha-blockade was started prior to availability of lab results due to high index of suspicion. Surgical removal, the mainstay of treatment, has yet to transpire as he has no family, and due to his underlying dementia, he was not felt to have capacity for decision-making at the time of diagnosis. The case elucidates the vast presentations of this tumour, the means of diagnosis and the difficulties of treatment.
