Abstract
We report the case of a 75-year old woman who presented with shortness of breath and haemoptysis. She had been treated for presumed essential hypertension for many years. On admission she was found to be severely hypertensive. Chest X-ray showed pulmonary oedema. However, an echocardiogram reported good systolic ventricular function. Her hypertension and pulmonary oedema did not respond to medical treatment necessitating intubation. A CT angiogram identified the cause – undiagnosed bilateral severe renal artery stenosis. We discuss this increasingly common condition that is difficult to manage and easily missed.

Abstract
A 25-year man presented to the Accident and Emergency Department complaining of dizziness and shortness of breath after taking 70 grams of cocaine over 10 hours. He said a friend had noticed that his skin had turned dark blue. On examination the patient was severely centrally and peripherally cyanosed. His pulse oximeter oxygen saturations were 88% on air. An arterial blood gas showed a methaemoglobin level of 45.6%. The patient was diagnosed with cocaineinduced methaemoglobinaemia and given methyl thioninium chloride (methylene blue). He made an uneventful recovery.
