Severe hypercalcaemia, nephrocalcinosis, and multiple paraffinomas caused by paraffin oil injections in a young bodybuilder

摘要

A 23-year-old bodybuilder presented in August, 2013, with a 24 h history of scrotal pain. Swabs for infection, and abdominal CT scan for nephrolithiasis, were negative, but blood tests showed anaemia, renal insufficiency, and severe hypercalcaemia (free calcium 2-29 mmol/L, normal: 1-18-1-32 mmol/L). C-reactive protein was normal. He had suppressed parathyroid hormone, raised angiotensin-converting enzyme and interleukin receptor levels, low 25-hydroxyvitamin D, and high 1,25-dihydroxyvitamin D. Physical examination revealed many warm, dense nodules in the skin and subcutaneous tissue overlying the pectoral, trapezius, and biceps muscles.
