Clival meningioma

Case contributed by Dr Amr Farouk

Presentation

Post operative status for 50 year old patient underwent ventricular shunting

Patient Data

Age: 50 year old
Gender: Female
MRI

A large pre-pontine extra-axial SOL is seen related to the posterior aspect of the clivus and extends into the left cerbello-pontine angle. It is eliciting isointense signal to grey matter on both T1 and T2 sequences and demonstrates vivid contrast enhancement with enhancing meningeal dural base. In DWI and ADC images it show similar signal intensity to brain. It displaces the basilar artery and distorts the brain stem and results in compression of the fourth ventricle. The SOL is seen extending cranially to supra-sellar cistern. No bony invasion. 

A ventricular shunt tube is noted with no supra-tentorial hydrocephalic changes.

Case Discussion

MRI picture is in keeping with a meningioma including a isointense signal to grey matter on T1 and T2 WIs, intense homogenous enhancement and dural tail.  

 A clival meningioma is one of the more uncommon sites for this common pathology.
