Isolated prostate cancer metastasis to the adrenal gland is rare. We report a case of concordant high uptake in a solitary adrenal metastasis on both prostate-specific membrane antigen and fluorodeoxyglucose positron-emission tomography in a patient with castrate-resistant prostate cancer. Good initial biochemical response was achieved with laparoscopic adrenalectomy. The patient developed lymph node recurrence 12 months later, although remains asymptomatic on hormonal treatment 22 months post-operatively, in keeping with prior results for metastasis-directed therapy which can delay time to additional treatment. Application of dual tracer PET can be valuable for prostate cancer staging and guidance of metastasis-directed treatment.

SUMMARYWe present a case of bilateral adrenal haemorrhage (BAH) associated with heparin-induced thrombocytopaenia (HIT) in a 61-year-old man admitted to hospital for the treatment of Fournier's gangrene. He presented to hospital with scrotal swelling and fever, and developed spreading erythaema and a gangrenous scrotum. His scrotum was surgically debrided and intravenous broad-spectrum antibiotics were administered. Unfractionated heparin was given postoperatively for venous thromboembolism prophylaxis. The patient deteriorated clinically 8-11 days postoperatively with delirium, chest pain and severe hypertension followed by hypotension and thrombocytopaenia. Abdominal CT scan revealed bilateral adrenal haemorrhage. Antibodies to the heparin-platelet factor 4 complex were present. HIT-associated BAH was diagnosed and heparin was discontinued. Intravenous bivalirudin and hydrocortisone were started, with rapid improvement in clinical status. BAH is a rare complication of HIT and should be considered in the postoperative patient with unexplained clinical deterioration. BACKGROUND

A 71-year-old white woman was referred to the emergency department by her primary care physician for necrosis and swelling of the left great toe for work-up of possible osteomyelitis (Figure 1). Before she presented to her physician, she had been complaining of severe pain, swelling, and erythema of the left great toe that had lasted for 1-2 months. Infection was initially suspected. She completed 2 courses of oral antibiotics with no improvement. She was also complaining of similar symptoms on the left index finger and attributed her symptoms to an injury a month earlier (Figure 2). The pain was so severe that she was not able to bear weight on her left foot. An outpatient X-ray of her left great toe raised her physician's concerns that it might be osteomyelitis so she was referred to the emergency department.
