Abstract
Background
Computed tomography (CT) and magnetic resonance (MR) represent the gold standard for evaluating intracranial tumours, such as meningiomas; most meningiomas can be managed by surveillance and clinical follow-up, therefore, the ideal technology should be cheap, non-invasive, safe and able to reduce radiation exposure. Transcranial colour-coded duplex sonography (TCCS) can detect space-occupying lesions, but its full potential for clinical practice is still unexpressed.
Aims and Methods
We describe the ability of TCCS to directly and accurately image, in a 77-year-old woman hospitalised for septic shock and coma, a suprasellar meningioma with a spatial resolution very similar to CT.
Results
The meningioma was clearly visualised as a roundish mass, with well-defined borders, heterogeneously hyperechogenic compared with the surrounding brain structures; multiple intralesional calcifications were detectable as highly echogenic spots. Latero-lateral and antero-posterior diameters were well measurable.
Discussion
TCCS should not be considered as an alternative to CT and MR imaging, but it might have a complementary role, useful for use at the bedside in uncooperative or non-transportable patients and for follow-up, when an adequate acoustic window is guaranteed. Neurologists and neuroradiologists should further explore the full potential of this technology.
