BACKGROUND: Few reports exist regarding @entity439 where the initial work up was concerning for a @entity5 . To date, no published reports exist regarding a nongiant thrombosed @entity438 , where the primary workup and treatment plan was directed toward a preliminary diagnosis of @entity5 . CASE DESCRIPTION: We report a 43-year-old female who presented with a generalized @entity410 attributed to a lesion along the right superior temporal gyrus. The lesion enhanced on initial magnetic resonance imaging (MRI) of the brain, as well as on follow-up MRI. Subsequent vascular studies and metastatic work up were negative. A craniotomy with image guidance was performed and an intraoperative diagnosis was made of a thrombosed @entity439 along a branch of the middle cerebral artery. The @entity439 was trapped and resected as there was no significant flow from the branch as seen on the prior cerebral angiogram. The @entity1 had an uneventful postoperative course. CONCLUSION: Completely thrombosed, nongiant @entity439 can mimic an @entity5 . Typical imaging features for @entity439 may be missed, especially if the @entity439 are small, where imaging characteristics of the intraluminal contents is more difficult to appreciate. Although imaging may be consistent with a @entity1313 , there should be suspicion for a potential underlying @entity439 .
