Case presentation

A 54-year-old Caucasian male non-smoker presented to the Emergency Department with severe left loin pain of sudden onset for the last 3 h. He reported frequent migraines for the last 20 years, for which he had been taking occasional ergotamine 1 mg/caffeine tablets, obtained over-the-counter overseas. The migraines had worsened recently, attributed to stress at work and therefore he had been taking the ergotamine almost daily. On the day prior to admission, he had taken three tablets over 24 h, and reported increasingly severe episodes of loin pain occurring about 1 h after administration of the second and third doses.

Examination revealed left renal angle tenderness and vital signs included temperature 36.7 °C, blood pressure 129/75, pulse 62/min, pulse oximetry 99% on air. Bedside abdominal ultrasound was unremarkable. Dipstick urinalysis and microscopy, and serum Creatinine were normal. C-reactive protein was mildly elevated at 15 mg/L. Contrast enhanced computed tomography (CT) of the abdomen revealed left renal infarcts (Figure 1). Twenty-four hour electrocardiogram revealed normal sinus rhythm throughout. Echocardiogram was normal with no intracardiac thrombus. Thrombophilia screen was unremarkable.
