History: Left parietal intracranial hemorrhage follow-up Bilobed shape left frontal parietal hematoma is again seen. It appears slightly different on the current CT due to technique and angle of acquisition when compared to the recent brain MRI. Left high convexity frontal lobe hematoma, slightly ill defined and relatively hypodense, measuring about 2.2 x 1.9-cm. More inferiorly, the left frontal parietal lobe hematoma measures 2.3 x 2.4-cm. They are associated with large amount of adjacent edema. Trace amount of adjacent subarachnoid blood are also seen, unchanged. There are mild to moderate diffuse cerebral edema overall with paucity of extra axial space and sulci, effacement of basal cisterns, especially in the left. There is probable left-sided uncal herniation. No evidence of midline shift. The lateral ventricles are compressed. No hydrocephalus. Marked mucosal thickening with bubbly material seen in the sphenoid sinuses. Large right maxillary sinus retention cyst or polyp is present. Left inferior mastoid air cells opacification, left more than right. Minimal mucosal thickening seen in the ethmoid sinuses. Small right frontal sinus osteoma.
1. Left frontoparietal hematoma as described above with large amount of adjacent edema. Diffuse overall brain edema with paucity of extra-axial space and sulci, decrease in visualization of the left suprasellar cistern raising the possibility of left-sided uncal herniation. 2. Within limit of the comparison between current CT and prior MRI, there is no conclusive evidence of new separate intracranial hemorrhage.
