Background: Nonmissile penetrating spine injury (NMPSI) represents a small percent of spinal cord injuries (SCIs), estimated at 0.8% in Western countries. Regarding the causes, an NMPSI injury caused by a screwdriver is rare. This study reports a case of a retained double-headed screwdriver in a 37-year-old man who sustained a stab injury to the back of the neck, leaving the patient with a C4 Brown-Sequard syndrome (BSS). We discuss the intricacies of the surgical management of such cases with a literature review. Methods: PubMed database was searched by the following combined formula of medical subjects headings, (MESH) terms, and keywords: (((SCIs [MeSH Terms]) OR (nmpsi [Other Term]) OR (nonmissile penetrating spinal injury [Other Term]) OR (nonmissile penetrating spinal injury [Other Term])) AND (BSS [MeSH Terms])) OR (BSS [MeSH Terms]). Results: A total of 338 results were found; 258 were case reports. After excluding nonrelated cases, 16 cases were found of BSS induced by spinal cord injury by a retained object. The male-to-female ratio in these cases is 11:5, and ages ranged from 11 to 72. The causes of spinal cord injury included screwdrivers in three cases, knives in five cases, and glass in three cases. The extracted data were analyzed. Conclusion: Screwdriver stabs causing cervical SCIs are extremely rare. This is the first case from Iraq where the assault device is retained in situ at the time of presentation. Such cases should be managed immediately to carefully withdraw the object under direct vision and prevent further neurological deterioration.

Background: Anterior communicating artery (AcomA) aneurysms are considered one of the most common intracranial aneurysms, contributing to approximately 40% of the subarachnoid hemorrhages related to aneurysmal rupture. Aneurysms of the anterior circulation are commonly present with visual defects varying in their nature according to the aneurysmal site. However, complete bilateral vision loss associated with AcomA aneurysms is a significantly rare finding. We are reporting a case of complete bilateral blindness in a patient with a ruptured AcomA aneurysm with a literature review. Methods: We conducted a PubMed Medline database search by the following combined formula of subjects’ headings: (((Intracranial Aneurysm [MeSH Terms]) AND (AcomA Aneurysm [Title/Abstract])) AND [(Vision loss OR Blindness [Text Word])) AND (case reports [Filter]). Additional articles were searched through the reference lists of the included articles. Results: Our review yielded a total of five cases. All the present cases revealed unilateral blindness only, and their outcomes after treatment vary from recovery of vision to unchanged complete vision loss – none of the cases found in the literature presented with bilateral blindness. Conclusion: AcomA aneurysms can be associated with visual loss in some cases. However, usually, the defect is unilateral. Studies of the visual defects, including potential bilateral complete blindness associated with rupture inferiorly, directed AcomA aneurysm, should be highlighted.
