INTRACRANIAL ATHEROSCLEROSIS PRESENTING AS SUB ARACHNOID HEMORRHAGE - A UNIQUE SCENARIO

Mahnoor Hafeez, Binish Rasheed, Amjad Sattar

Abstract


Intracranial atherosclerotic disease (ICAD) represents the most common cause of ischemic stroke worldwide. Here, we present a unique manifestation of ICAD presenting as headache in a 53 years old Hypertensive and Diabetic patient. CT demonstrated sulcal sub-arachnoid hemorrhage (sSAH), with no infarct. He was referred to Dow University Hospital for CT Angiography examination, which revealed > 90% narrowing of the supraclinoid segments of Atherosclerotic internal carotid arteries (ICA) with extensive leptomeningeal collaterals, supplied by posterior circulation. To the best of authors’ knowledge, only single case analogous to it, on DSA has been published in the International Radiology literature.

Key words: CT angiography, intracranial arteriosclerosis, neuroradiology, non-aneurysmal sulcal sub arachnoid hemorrhage, sSAH.
