Only four cases of intracranial lipoma confined to the sylvian fissure have so far been reported. In this paper we describe an intracerebral lipoma that apparently arose from the connective tissue of the sylvian fissure in a 31-year-old male. To our knowledge, no other case of this kind has been reported. We successfully excised the entire tumor, using microsurgical techniques. The patient developed a minor motor deficit postoperatively, but eventually fully recovered.
