Clinical question: Evaluate for possible subdural. Signs and symptoms: Poor quality initial CT need to evaluate for subdural. Nonenhanced head CT:There is no evidence of intracranial hemorrhage.There is paucity of cortical sulci, sylvian fissures and a small basal cistern. Findings although may be the normal for patient stated age of 35 possibility of mild diffuse cerebral edema cannot be entirely ruled out. Comment current follow-up with an MRI examination.There is poor differentiation of gray -- white matter however I cannot be certain whether this is due to patient's thicker than normal calvarium and also presence of board under patient's head.
1.No evidence of parenchymal or subdural hematoma as clinically questioned.2.Paucity of cortical sulci and small size of basal cistern and sylvian fissures and poor differentiation of gray -- white matter as described above. Concern for possible underlying cerebral edema and recommend further follow-up with an MRI exam. Please see above comments.
