Clinical question: Worst headache of life, posterior headaches, left-sided weakness, slurred speech. Signs and symptoms: Worst headache of her life, posterior headache, left-sided weakness, slurred speech. Nonenhanced CT of brain:Images through posterior fossa are unremarkable.Edema in the right anterior temporal tip with a small amount of hemorrhage is noted. Combination of these findings measures approximately 46 mm x 25 minute periodsmall area of parenchymal edema in the right frontal pole measuring 19 mm times 19-mm. No hemorrhage associated with this finding.Minimal subarachnoid hemorrhage localized to the right anterior parietal region.Suspect a small CSF density extra-axial collection in the left frontal and temporal region. This finding measures approximately 4.5 Mm in size. The gray -- white matter differentiation is preserved. Ventricular system is within normal size and no midline shift.No -attenuation of the white matter of bilateral occipital lobes and is believed to be artifactual.Calvarium is intact. Visualized paranasal sinuses and mastoid air cells demonstrate minimal findings of acute sinusitis in the right maxillary sinus no detectable fracture on this exam. No definitive abnormality of the scalp. For further evaluation MRI examination of brain is recommended.
1.Foci of edema in the right anterior temporal tip with minimal hemorrhage and right anterior -- inferior frontal lobe without hemorrhage and minimal localized right parietal subarachnoid hemorrhage. Findings are suspected for posttraumatic changes. Follow-up with an MRI is recommended to exclude extent of injury or additional cause for these findings.2.Normal size of ventricular system and no midline shift.3.Negative calvarium.
