Abstract
Spontaneous disappearance of aneurysms, undetectable by conventional angiography, has been reported. This case report presents a patient with ventricular hemorrhage secondary to a ruptured lateral posterior choroidal artery aneurysm, confirmed by digital subtraction angiography (DSA). Without any intervention, follow-up DSA 11 months later showed an apparent "disappearance" of the aneurysm. However, high-resolution magnetic resonance vessel wall imaging revealed that the aneurysm had not indeed disappeared but had thrombosed, leading to a negative DSA appearance. By directly visualizing the vessel wall and intraluminal structures, magnetic resonance vessel wall imaging provides a valuable tool for the diagnosis and follow-up of negative aneurysms on DSA, enabling early detection of intraluminal thrombus formation.
期刊介绍：
Neurological Sciences is intended to provide a medium for the communication of results and ideas in the field of neuroscience. The journal welcomes contributions in both the basic and clinical aspects of the neurosciences. The official language of the journal is English. Reports are published in the form of original articles, short communications, editorials, reviews and letters to the editor. Original articles present the results of experimental or clinical studies in the neurosciences, while short communications are succinct reports permitting the rapid publication of novel results. Original contributions may be submitted for the special sections History of Neurology, Health Care and Neurological Digressions - a forum for cultural topics related to the neurosciences. The journal also publishes correspondence book reviews, meeting reports and announcements.
