The Iliad is an epic poem chronicling the journey of Achilles in the Trojan War. The poem is one of the earliest sources of written literature in the Western canon. It is not a medical text, but the many and varied descriptions of injuries and their consequences mean that it is an important source for examining the earliest notions of anatomy and knowledge of the pathologies that result from trauma. ⋯ Previous work on the poem has suggested an awareness of neurological concepts such as nystagmus, syncope, and pupillary dilatation after trauma. In this paper, we identify and categorize all of the head injuries detailed in the text and examine these to identify concepts of functional neuroanatomy that are revealed by the descriptions. We identify and discuss 2 detailed descriptions of head injury, suggesting an awareness of decerebrate posturing after brainstem injury and cerebrospinal fluid leakage following a basal skull fracture.

Microsurgical treatment of thrombosed middle cerebral artery (MCA) aneurysm is very complicated, especially in recurrent cases. A 48-year-old man presented with a recurrent thrombosed right MCA aneurysm. We performed MCA-to-MCA bypass using a superficial temporal artery (STA) interposition graft and proximal trapping. ⋯ We recommend this surgical technique in cases in which good STA backflow is guaranteed. In conclusion, revision surgery performed for a recurrent thrombosed MCA aneurysm with an MCA-STA interposition graft-MCA bypass with proximal trapping was successful. This technique is safe and effective for complex aneurysms with suboptimal condition of the STA, which could be due to reduced blood flow, previous surgery, or trauma.

This meta-analysis of published randomized controlled trials (RCTs) aimed to investigate the efficacy and safety of endovascular therapy (ET) for patients with acute ischemic stroke. ⋯ The findings of this meta-analysis suggest the incidence of a modified Rankin Scale score of 0-2 in patients who received ET was significantly increased. Moreover, the harmful effects of ET might exist due to greater risk of asymptomatic IH, subarachnoid hemorrhage, and non-intracerebral bleeding, and these results should be verified by further large-scale long-term RCT.

A high-riding vertebral artery (HRVA) has been defined as a C2 isthmus height of ≤5 mm and/or internal height of ≤2 mm measured 3 mm lateral to the border of the spinal canal. Its reported prevalence has varied widely. If overlooked during the approach for craniocervical fusion, injury to the vertebral arteries can occur, affecting the outcome. The present meta-analysis aimed to provide the pooled prevalence of HRVAs. ⋯ Craniocervical fusion should be preceded by examination of the vertebral arteries at the level of C2 because the presence of HRVAs is common and might preclude the safe insertion of transarticular or transpedicular screws.

Immunoglobulin G4-related Hypertrophic Pachymeningitis of the Spine: A Case Report and Systematic Review of the Literature.
Spinal immunoglobulin G4-related hypertrophic pachymeningitis (IgG4-HP) is a rare disease. Little information is known regarding the diagnosis, management, and prognosis of patients with spinal IgG4-HP. ⋯ Spinal IgG4-HP is a rare entity. In addition, it should be considered in the differential diagnosis of space-occupying lesions around the spinal cord. Histopathology with immunohistochemistry results provides the most reliable evidence for diagnosis. Steroid therapy is the first line of treatment. Surgical decompression may be required in patients presenting with nerve root and/or spinal cord compression. Long-term follow-up is necessary for patients with spinal IgG4-HP.
