Rare case of steroid cell tumour presenting as resistant hypertension in early pregnancy.

ABSTRACT

A woman 12 weeks and 3 days pregnant was referred to the emergency department with significant hypertension which, despite aggressive medical management, remained uncontrolled. Markedly elevated levels of renin and aldosterone beyond what is typical in early pregnancy were present, which together with the finding of a right ovarian cyst pointed to the possible diagnosis of an extrarenal reninoma.and the decision was made to perform a right-sided oophorectomy at 16 weeks gestation. Histology demonstrated a staining pattern most consistent with a steroid cell tumour leading to the diagnosis of refractory hypertension secondary to an ovarian steroid cell tumour. Post oophorectomy blood biochemistry rapidly returned to normal, and our patient's hypertension slowly resolved allowing for a large reduction in antihypertensive agent requirements and a successful pregnancy outcome.
