Clinical question: Rule out subdural. Signs and symptoms: Status post left parietal fracture from fall. Non-enhanced CT of brain:There is no evidence of a right small hemorrhage or subarachnoid hemorrhage.The cortical sulci, ventricular system and CSF cisterns remain within normal for patient stated age of 10 weeks. There is prominence of subarachnoid space in bifrontal, temporal and parietal regions which extends into the cement fissures bilaterally. This could be within normal for patient stated age. There is some inhomogeneity of the prominent subarachnoid space which also may be secondary to motion artifact. There is no detectable mass effect on the parenchyma. The entirely exclude the possibility of isodense subdural follow-up with an MRI is recommended.Examination demonstrates a linear nondisplaced fracture of left parietal bone which is best appreciated on bone density images 23 through 27.
1.No definite abnormality of brain parenchyma or subarachnoid hemorrhage.2.Prominent subarachnoid space which could be within normal for patient's stated age however it cannot exclude possibility of isodense subdural. There is no detectable mass effect on the brain parenchyma.3.Nondisplaced fracture of left parietal bone.4.There are no old studies for comparison.5.Visualized mastoid air cells and middle ear cavities and limited view of paranasal sinuses are unremarkable.
