Microsurgical excision of a ruptured distal lenticulostriate aneurysm in a child.

Distal lenticulostriate artery aneurysms are rare but potentially fatal conditions, especially in children. Endovascular management is often considered the first-line treatment, but microsurgical excision may be necessary in certain cases. This article presents a case report of a child with a ruptured distal lenticulostriate artery aneurysm that required careful decision making and preparation before microsurgical excision. MR angiography was performed in the planning phase and neuronavigation was used during surgery. The surgery was a success, with the patient suffering minimal postoperative focal deficit, which later turned out to be transient.
