headache during sex No evidence of acute ischemic or hemorrhagic lesion on this scan.The ventricles, sulci and cisterns are symmetric and unremarkable. The gray-white matter differentiation is normal. There is no mass, mass effect, edema, midline shift, intra or extra-axial fluid collection/hemorrhage, restricted diffusion/acute ischemia, or abnormal contrast enhancement. The midline structures and cranial-cervical junction are normal. The mastoid air cells are clear.The left side sphenoid sinus shows opacification.3D time of flight MOTSA MRA brain images with maximum intensity projections of the anterior/posterior intracranial circulation demonstrate normal flow enhancement in bilateral ICAs, MCAs and ACAs.Bilateral Pcom arteries were identified and patent. Acom artery is also patent.There is no evidence of intracranial arterial aneurysm, significant intracranial arterial luminal stenosis or occlusion.Smaller than 3mm sized intracranial arterial aneurysm cannot be identified on MR angiography. Therefore, if clinically indicated, diagnostic cerebral angiography can be considered for further evaluation.
1. No evidence of acute ischemic or hemorrhagic lesion on this scan.2. Left sphenoid sinus opacification.3. No evidence of intracranial aneurysm on MRA.Rec: If clinically indicated, diagnostic cerebral angiography can be considered for further imaging evaluation.
