Acute Non-Traumatic Sub-Arachnoid Hemorrhage in a Young Female With Diabetic Ketoacidosis.

Diabetic ketoacidosis (DKA) is one of the most common causes of morbidity and mortality in patients with type 1 DM. Due to severe acidosis, ketonemia and electrolyte disturbances it can lead to various complications in the body, which can be fatal in some cases. Neurological complications related to DKA include cerebral edema, cerebral infarction, brain herniation, cortical venous thrombosis. It is very rare for DKA to cause subarachnoid hemorrhage (SAH). We present a case 19-year-old female with severe DKA, who developed SAH without any pre-existing aneurysm or other common risk factors. The patient did not have any neurologic deficits and was managed conservatively with the resolution of her symptoms. We have also summarized the existing literature regarding the association of DKA with subarachnoid hemorrhage.
