This 37-year-old female with two days headache. Rule out subarachnoid hemorrhage. There is a hyperdense extra-axial mass in the left subarachnoid space of the high convexity. There is suspected communication between this mass and a hyperdense tubular structure that extends from the high left convexity into the brain parenchyma. Intraparenchymal hypodensity around this tubular structure may represent edema. An MRI is recommended for further evaluation of this mass.There is no evidence of intracranial hemorrhage or midline shift. The ventricles and basal cisterns are normal in size and configuration.The calvaria and skull base are radiographically normal. The visualized paranasal sinuses and mastoid air cells are normally pneumatized.These findings were discussed with Dr. Jeffrey Kuo at the time of interpretation.
