Headache(784.0) [784.0] / Subarachnoid hemorrhage [430], Reason for Study: ^Reason: evaluate for SAH, angio today consistent w/ vasospasm RCVS vs. Vasculitis History: recurrent thunderclap headache, beading on angiogram There is no evidence of acute ischemic or hemorrhagic lesion on the scan.The left lateral orbital gyrus is prominent and appears to be connected to the left inferior frontal lobe pars orbitalis. However, there is no evidence of abnormal gray matter and the thickness of gray matter on this region appears to be normal indicating normal variation. The ventricles, sulci and cisterns are symmetric and unremarkable. There is no mass, mass effect, edema, midline shift, intra or extra-axial fluid collection/hemorrhage, or restricted diffusion/acute ischemia. The midline structures and cranial-cervical junction are normal. Normal flow voids are identified in the major intracranial vessels. The paranasal sinuses and mastoid air cells are clear.
No evidence of acute ischemic or hemorrhagic lesion.No evidence of intra and extra axial mass lesion.Normal variation of left lateral orbital gyrus connection to the left inferior frontal gyrus pars orbitalis.
