A pediatric case of completely thrombosed giant cavernous carotid aneurysm with ipsilateral ICA occlusion mimicking an intra-axial cystic lesion: a case report and review of the literature

Thrombosed MCA Aneurysm Mimicking an Insular Cavernous Angioma: A Case Report and Literature Review

“…Angiography was not performed but would probably has been normal in CTA. The literature reports few cases of CTA that mimic intracranial lesions [7] , [8]: schwannoma [9], [10], CCM [11], [12], dermoid cyst [13], ependymoma [14], meningioma [15], epidermoid cyst [16] and glioma [17] (table 1). To our knowledge, only 2 cases of CTA that mimicked CCM are reported (1 giant [11] and 1 medium [12]).…”

Spontaneous thrombosis of a large unruptured intracranial aneurysm causing ischemic stroke due to occlusion of the parent artery: A case report and literature review

“…Notably, diagnosing a case of IS based on the mechanism of thrombosis developing to fill the lumen of an unruptured aneurysm and invading the parent artery is not simple for several reasons. First, the imaging of a completely thrombosed aneurysm is difficult to distinguish from other lesions, especially brain tumors [6 , [15] , [16] , [17] , [18] ] and cavernoma [5 , [19] , [20] , [21] ]. Even the “gold standard” for diagnosing cerebrovascular disease, digital subtraction angiography (DSA), is also difficult to distinguish and the results are usually “negative”.…”

Commentary: Common Carotid Artery to Middle Cerebral Artery Bypass With Radial Interposition Graft for Internal Carotid Artery (ICA) Occlusion After Stent-Coil Embolization of Giant ICA Terminus Aneurysm: 2-Dimensional Operative Video

“…7 Giant aneurysms can cause morbidity through rupture, as well as mass effect including cranial neuropathy, seizures, and other neurological symptoms. Spontaneous thrombosis has been documented in giant aneurysms [8][9][10] ; notably, spontaneous partial thrombosis may worsen natural history. 11,12 Even complete thrombosis has been associated with rupture.…”
