ABSTRACT
Meningioangiomatosis (MA) represents a vascular hamartoma accompanied by meningothelial cell proliferation. It generally becomes symptomatic with difficult to control seizures, though in some patients it may be asymptomatic. We present the case of a 41-year-old male patient with a newly developed central distal monoparesis of the left leg. Cranial magnetic resonance imaging (MRI) and further diagnostic characterization via (18)F-Fluoro-Ethyl-Tyrosine positron emission tomography ((18)F-FET-PET) indicated a low-grade glioma. Histopathological diagnosis revealed a meningioangiomatosis. The clinical, radiological and neuropathological findings of this rare constellation are described and discussed with the actual literature.

Bilateral intracavernous carotid artery aneurysms are very rare and can be usually observed in patients with multiple intracranial aneurysms. Here we present the case of a 73 year-old woman who experienced worsening diplopia due to progressive bilateral paresis of the lateral rectus muscles. Computed tomography (CT) and magnetic resonance imaging (MRI) examinations showed bilateral roundish parasellar and intracavernous masses, with homogeneous contrast-enhancement and absence of subarachnoid haemorrhage (SAH). Cerebral angiography revealed bilateral aneurysms of the intracavernous carotid artery. Once considered the age of the patient, the anatomical features of the aneurysms and the risks of traditional or endovascular surgery, we decided not to proceed to any treatment other than the orthoptic correction of the diplopia and the careful correction of arterial hypertension. We provide a brief review of the literature on bilateral intracavernous aneurysms and a discussion about their treatment.
