[Putaminal hemorrhage in a case of Turner's syndrome with hyperaldosteronemia]

A case of Turner's syndrome complicated with intracerebral hemorrhage in a 21-year-old female is presented. The patient experienced acute onset of unconsciousness and the left-sided hemiparesis due to the right-sided putaminal hemorrhage. Severe hypertension was seen at the hospitalization. Cerebral angiography revealed no vascular lesion other than the displacement of lenticulostriate arteries. Emergent surgical evacuation of the hematoma was successfully performed with her favorable outcome. Postoperatively, several hormonal tests indicated hyperaldosteronemia secondary to the increased levels of ACTH and renin as a result of hyper-response to the environmental stress, leading to critical hypertension. Other examinations including CT scan, MRI, MRA, and laboratory data showed no abnormalities suggestive of renal lesions. It is supposed that hypertension, as a frequent presenting feature, should be strictly controlled in Turner's syndrome from the first time of diagnosis.
