Congenital adrenal hyperplasia due to 11 ? hydroxylase deficiency masquerading as testicular tumours and myopathy in children

A 10 year and 2 month old boy was transferred to Lady Ridgeway Hospital (LRH) in March 2007 for further evaluation. He was the youngest of 7 children born to unrelated parents. He had always been dark complexioned. There was no history suggestive of an adrenal crisis during the neonatal period, infancy or childhood. An increase in his height had been noted around 8 years of age followed by appearance of secondary sexual characteristics one year later. He was taller than his 13 year old brother who was prepubertal. His parents did not think this abnormal and had not sought medical advice. A month prior to admission he had developed a headache which progressively worsened and when taken to the local hospital hypertension was detected. He was also suspected to have testicular tumours and was transferred to LRH for further assessment.
