We present the case of T.F., a 28-year-old woman diagnosed with corpus callosum dysgenesis and colpocephaly. The diagnosis is based on cerebral imaging – magnetic resonance imaging (MRI) and computerised tomography (CT).

Optic nerve sheath meningiomas (ONSM) are rare, frequently unilateral, benign, slowly growing tumors, arising from the meningo-epithelial cells surrounding the optic nerve intraorbital or intercanalicular. Their localization directly impair vision and indirectly impair aesthetics, making a safe classical surgical intervention very difficult and recommending stereotactic fractionated radiotherapy. Women are more affected, the survival rate is good and imaging can sustain differential diagnosis with optic neuroglioma or orbital schwannoma, lymphoma or pseudo tumor.

We present the case of a 60 year-old woman diagnosed with meningiomatosis (multiple sporadic meningiomas), in the absence of neurofibromatosis type 2. The cerebral computerized axial tomography (CT scan) revealed six expansive lesions (one isodense and five spontaneously hyperdense partially or completely calcified), which at the cerebral magnetic resonance imaging (MRI) examination showed typical features of meningiomas. Case particularity: the very low incidence of sporadic multiple meningiomas and a rare cause of secondary epilepsy.

Cerebral cavernous venous malformations (also called cavernous hemangiomas or cavernomas) are the third most common cerebral vascular malformations having an incidence of 0.4-0.8% in the general population and being diagnosed more frequently incidentally during an imaging procedure. Usually solitary, but cavernomas can also be present as multiple lesions with autosomal dominant inheritance pattern. We present a rare case and the MRI imaging of a type I Zabramski cavernoma that bled, localized in the medulla oblongata of a 41-year-old man, admitted with paresthesia of the right upper limb, very mild right hemiparesis and impaired fine motor movements of the right hand and intractable persistent hiccups.
