Non-aneurysmal non-traumatic subarachnoid hemorrhage: think also in acute promyelocytic leukemia.

Differentiation between traumatic tap and aneurysmal subarachnoid hemorrhage: prospective cohort study

OBJECTIVES To describe the findings in cerebrospinal fluid from patients with acute headache that could distinguish subarachnoid hemorrhage from the effects of a traumatic lumbar puncture. DESIGN A substudy of a prospective multicenter cohort study. SETTING 12 Canadian academic emergency departments, from November 2000 to December 2009.

Isolated non-traumatic, non-aneurysmal convexal subarachnoid hemorrhage in a patient with Evans syndrome

BACKGROUND Non-traumatic, spontaneous subarachnoid hemorrhage occurs in approximately 85% of cases where there is a ruptured saccular aneurysm. An additional 10% of cases arise from non-aneurysmal peri-mesencephalic hemorrhages. CASE PRESENTATION We report a rare case of a young female, with underlying Evans syndrome, who was initially thought to have non-hemorrhagic stroke, eventually diagno...

Familial perimesencephalic subarachnoid hemorrhage: two case reports

INTRODUCTION Non-aneurysmal spontaneous subarachnoid hemorrhage is characterized by an accumulation of a limited amount of subarachnoid hemorrhage, predominantly around the midbrain, and a lack of blood in the brain parenchyma or ventricular system. It represents 5% of all spontaneous subarachnoid hemorrhage cases. In spite of extensive investigation, understanding of the mechanisms leading to ...

Clinical Course of Non-Traumatic Non-Aneurysmal Subarachnoid Hemorrhage: A Single Institution Experience over 10 Years and Review of the Contemporary Literature.

AIM To report our experience with a relatively large series of patients with non-traumatic non-aneurysmal subarachnoid hemorrhage (NNSAH) to identify the prognosis associated with different bleeding patterns as well as a further diagnostic work-up to determine the underlying cause. MATERIAL AND METHODS Between January 2004 and December 2014, 81 patients with angiography-negative non-traumatic...
