Causes of spontaneous subarachnoid hemorrhage in Thai infants and children. A study of 56 patients.

The authors report 56 cases of spontaneous subarachnoid hemorrhage in Thai infants and children. The causes were: hemorrhagic disorders in 22 cases, arteriovenous malformations and aneurysms in 18, gnathostomiasis in nine, bleeding tumors in four, hypernatremia in one, and undertermined causes in two cases. Coagulation studies and cerebrospinal fluid examination for eosinophils are recommended before further invasive studies in such cases.
