Abstract:
BACKGROUND:Intraorbital and intracerebral cavernous malformation (CM) lesions are considered independent entities. Purely cerebral CMs have variable biology with recent evidence depicting inflammation as an important player and a risk factor for aggressiveness. We describe a case of concomitant left intraaxial and extraaxial CMs, linked by the ipsilateral basal vein, where the extraaxial component has developed an aggressive behavior. CASE DESCRIPTION:A 35-year-old female patient presented with a rapid and progressive exophthalmos and loss of vision on the left eye. Cranial magnetic resonance and angiography examinations demonstrated a left craniofacial CM and large intraorbital component. The lesion was connected through a large basal vein to a cerebral intraventricular CM. Transconjunctival resection showed typical findings of CM. A complete histopathology and immunostaining analysis was performed and revealed a clear acute lymphomononuclear reaction with a predominant immune cellular inflammation. CONCLUSIONS:A case of intraorbital and extracranial cavernomatous mass, connected to a cerebral intraventricular CM through a large basal vein, has presented with an aggressive course. A complete histopathologic and immunohistochemical analysis of the orbital mass has pictured a clear immune-cellular inflammatory reaction adding to the amounting evidence of association between inflammation and site aggressiveness in the setting of CMs.
