Headache [R51] / Unspecified ptosis of left eyelid [H02.402] / Ocular pain, left eye [H57.12], Reason for Study: ^Reason: mass? History: HA, L eye ptosis, L eye pain Brain MRINo evidence of acute ischemic or hemorrhagic lesion.The ventricles, sulci and cisterns are unremarkable. 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 paranasal sinuses and mastoid air cells are clear.Orbit MRIThe globes, optic nerves, extraocular muscles and retroglobal spaces are symmetric and normal. The lacrimal glands are normal. There is no evidence of signal abnormality, mass, or abnormal contrast enhancement. Brain MRA3D time of flight MOTSA MRA brain images with maximum intensity projections of the anterior/posterior intracranial circulation demonstrate about 5.5mm x 2.9mm sized left posterior communicating artery aneurysm. Vertebrobasilar system appears to be normal.Neck MRA3D MRA neck post-gadolinium images with maximum intensity projections of the cervical vasculature demonstrate normal flow enhancement in a normal aortic arch origin of the right brachiocephalic, left common carotid, and left subclavian arteries. The vertebral artery origins are normal. There is normal flow enhancement through the bilateral common carotid, carotid bifurcations, internal/external carotid, and vertebral arteries.
1. 5.5mm x 2.9mm sized left Pcom artery aneurysm.2. No evidence of acute ischemic or hemorrhagic lesion. No abnormal enhancement. No abnormal signal intensity.3. No evidence of intracranial arterial luminal stenosis.4. No evidence of extracranial arterial luminal narrowing. Neurosurgery and neurology teams were informed at the time of this dictation.
