Putaminal Hemorrhage Associated with Subarachnoid Hemorrhage: Case Report

ABSTRACT

The preferred site of spontaneous intracerebral hemorrhage(SICH) is the supratentorial area, especially the basal ganglia. Large hematomas frequently spread into the ventricle, and in the case of intraventricular hematomas, varying degrees of fresh blood are found within the subarachnoid space. Cases in which SICH of the basal ganglia ruptures the insular cortex and causes thick subarachnoid hemorrhage(SAH) in the basal cisterns, are, however, rare. The authors report a rare case of putaminal SICH with intraventricular hemorrhage(IVH) and SAH in the basal cisterns. This 58-year-old female was stuporous on admission. Neurological examination revealed Glasgow coma scale score 7, left hemiparesis, positive Babinski's sign and neck stiffness. Brain CT showed a large intracerebral hematoma in the right basal ganglion and associated intraventricular hematoma and SAH in the basal cistern. Cerebral angiography demonstrated a small saccular aneurysm at the right M1. Right pterional and trans-sylvian approach revealed thick SAH in the sylvian fissure and a small unruptured aneurysm at the early bifurcation of the middle cerebral artery. The putaminal hematoma had ruptured into the sylvian fissure through a natural opening at the insular cortex between M2 branches. This case illustrates that hypertensive SICH should be included in the differential diagnosis of basal cistern SAH associated with SICH.
