Foramen magnum meningioma (MR).

PROTOCOL:

T2W – Sagittal & axial scans

T1W – Axial scans

FLAIR – Coronal scans

T2FFE (Gradient) – Axial scans

3D TOF MR angiography of the circle of Willis vessels and MIP reconstruction.

FINDINGS:

-Revealed:

·        A right cerebello-pontine angle soft tissue mass extending to the right side of foramen magnum resulting in compression of the medulla and the upper cervical cord.

·        Measurements of about 25 mm (AP) X 19 mm (transverse) x 27 mm (height).

·        Homogenous enhancement after contrast injection.

·        Dural tail and dural base of the mass.

-Brain Parenchyma shows normal grey white matter differentiation and signal intensities.  No focal mass lesion is seen.

-Lateral and third ventricles are normal in size and position. Septum is in midline.  There is no midline shift.

-Basal cisterns, cortical sulci and gyri are normal in appearance.

-Corpus callosum shows normal MR morphology.

-Fourth ventricle is normal in size and is midline in position.

OPINION:

·        Picture is suggestive of a meningioma of right cerebello-pontine angle extending to the right side of foramen magnum resulting in compression of the medulla and upper cervical cord to the left side.
