Other convulsions [780.39], Reason for Study: ^Reason: rule out structural lesion that may exl History: seizures >5x PTA, left hemihypoesthesia, left lower extremity weakness No evidence of acute ischemic or hemorrhagic lesion.There is evidence of right occipital craniectomy.Underlying brain parenchyma shows encephalomalacia on the right parieto-occipital lobe with ex focal changes of right lateral ventricle occipital horn indicate prior ischemic stroke.Gradient echo images shows susceptibility artifacts on transabdominal osseous area as well as the left occipital lobe indicate chronic blood products.There is no abnormal enhancement.The ventricular system is unremarkable.The cranial-cervical junction is normal. Normal flow voids are identified in the major intracranial vessels. The mastoid air cells are clear.Opacification with mucosal thickening was seen on bilateral maxillary sinus as well as ethmoid sinuses
Right occipital craniectomy with temporo-occipital encephalomalacia as described above.No evidence of acute ischemic or hemorrhagic lesion on the scan.No evidence of abnormal enhancement.
