MRI
What is the common clinical presentation of meningioma?
Many small meningiomas are found incidentally and are entirely asymptomatic. Often they cause concern as they are mistakenly deemed to be the cause of vague symptoms, most frequently headaches. Larger tumours, or those with adjacent oedema or abutting particularly sensitive structures can present with a variety of symptoms. Most common presentations include: headache, paresis, change in mental status, focal neurological deficit
2 lesions can be identified on MRI images
1st extra axial lesion locate in the left anterior cranial fossa. The lesion is heterogeneous in nature & shows iso-intensity & hypo-intense centre on both T1 & T2. The lesion is enhanced after admission of contrast which shows a well defined border with irregular shape. The lesion is protruding across mid-line & causing mass effect with herniation & distortion of ventricles best seen on T1 C+
2nd lesion locates in frontal/parietal bone of skull. The heterogeneous lesion has ill defined border with similar intense to the rest of skull in both T1 & T2. The lesion doesn't appear to be enhanced after admission of contrast
