Clinical question: Any sign of bleed or worsening mass in the head. Signs and symptoms: Weakness Unenhanced CT of brain:Images through posterior fossa demonstrate an old left cerebellar stroke with no interval change.Images through the supratentorial space demonstrate prominence of cortical sulci and ventricular system for patient's age similar to prior exam.Area of low-attenuation involving the white matter of the left posterior temporal and parietal consistent with vasogenic edema/encephalomalacia. The distribution of this finding is fairly similar to prior exam. A subtle mass effect with the above findings. There is revisualization of a mass along the falx on the left in the posterior parietal -- occipital region. This mass appears slightly smaller than prior exam however without dedicated enhanced imaging precise comparison is not possible.No attenuation of periventricular white matter of right hemisphere is similar to prior exam and may represent postradiation change.There is no evidence of intracranial hemorrhage, midline shift or hydrocephalus. Follow-up with an MRI or an enhanced CT is recommended.Stable post craniotomy changes of the left parietal.Visualized paranasal sinuses and mastoid air cells are unremarkable.
1.Revisualization of a mass in the left occipital -- posterior parietal lobe with extensive surrounding vasogenic edema/encephalomalacia with no evidence of interval hemorrhage. Without an enhanced study precise comparison is not possible.2.There is no evidence of acute intracranial hemorrhage or midline shift.3.Prominence of ventricular system and cortical sulci for patient of stated age of 56 this is stable since prior exam.
