Technique: Non-contrasted volumetric acquisition through the brain.
Findings: There is no intracerebral or subarachnoid haemorrhage. There is no extra-axial collection.
The basal cisterns and ventricles are unremarkable in their appearance and anatomy.
There is a hyperdense mass present within the superior right frontotemporal lobe measuring 2.3 cm x 2.7 cm in size. There is associated oedema. The mass appears to be durally based and may represent the presence of a meningioma. Correlation to any previous imaging is recommended. Further evaluation with contrast enhanced CT scan and MRI could be considered. The midline remains central.
There is an unremarkable appearance to the craniocervical junction and pituitary fossa. No orbital or retro-orbital abnormality is demonstrated. The visualised portions of the paranasal sinuses appear unremarkable. The mastoid air cells remain aerated.
No expansile or lytic osseous lesion is seen. No significant subgaleal haematoma is evident. No definite skull base or calvarial fracture is identified.
Conclusion: Hyperdense, likely extra-axial mass within the right frontotemporal lobe, with associated oedema. Correlation to previous imaging is recommended. Further assessment with contrast enhanced imaging and/or an MRI is recommended.
