Abstract :
Meningiomas are the most common primary brain tumors, accounting for approximately 30% of all intracranial neoplasms. These tumors originate from the meninges, the protective membranes surrounding the brain and spinal cord, and are typically classified as benign, although some may exhibit atypical or malignant characteristics. Meningiomas are more prevalent in adults, particularly in women, and often arise in areas such as the convexity of the brain, the sphenoid ridge, and along the falx cerebri. Symptoms can vary widely, depending on the tumor's location and size, and may include headaches, seizures, and neurological deficits. While many meningiomas are asymptomatic and discovered incidentally, treatment options often involve surgical resection and, in certain cases, radiation therapy. Understanding the imaging characteristics and clinical implications of meningiomas is crucial for accurate diagnosis and effective management
We present the case of a 68-year-old female with headaches and seizures CT brain plain and MRI scan of the brain was performed using T1 & T2 weighted sequences in multiple planes.
A large well-defined prepontine extra-axial space occupying lesion was in relation to the posterior aspect of the clivus and extends into the left cerebellopontine angle. It was eliciting isointense signal to grey matter on both T1 and T2 sequences and demonstrated vivid contrast enhancement with enhancing meningeal dural base known as dural tail sign.Anteriorly the mass was causing erosions on clivus & bilateral temporal bones. Mild mass effect was in the form of mild compression on midbrain, pons, and 3rd ventricle & left medial basal temporal lobe. Mild dilatation of all four ventricles with minimal periventricular CSF seepage suggestive of perilesional vasogenic oedema and communicating hydrocephalus. Large areas of cerebral edema was noted in both thalami, midbrain, pons superior & middle cerebellar peduncles and anterior cerebellar hemispheres on both sides.It was showing foci of blooming on SWI suggesting intralesional calcification Features are suggestive of clival meningioma
Clival meningioma is one of the less common sites for this pathology.
