Cavernoma in the medulla oblongata – Case presentation and review of the literature

Abstract

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 bleeded, 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 persistant hiccups.
