Aneurysms arising from the posterior communicating artery (PCoA) itself are rare in which aneurysms usually located in the proximal portion of the PCoA. The authors report a case of the true PCoA ruptured aneurysm in the distal portion of the PCoA. ⋯ We speculated that blood flow into the PCoA gradually increased after occlusion of the left vertebral artery, which induced tortuosity of the PCoA. As a result, hemodynamic stress might increase near the curvature and cause aneurysm formation.

Coccidioidomycosis is a fungal infection that is endemic to parts of the Southwestern United States. When infection involves the spine, the treatment strategies can be challenging. We have devised a management protocol for spinal coccidioidomycosis based on a review of the literature and our experience. ⋯ This work provides a working protocol involving assessment and reassessment for the management of spinal coccidioidomycosis. Medical management with antifungal agents in some cases can provide satisfactory disease control. However, in patients with mechanical instability, neurologic deficit, medically intractable pain or disease progression disease control may only be achieved with surgical debridement and stabilization.

The efficacy of epidural and facet joint injections has been assessed utilizing multiple solutions including saline, local anesthetic, steroids, and others. The responses to these various solutions have been variable and have not been systematically assessed with long-term follow-ups. ⋯ This systematic review showed equal efficacy for local anesthetic with steroids and local anesthetic alone in multiple spinal conditions except for disc herniation where the superiority of local anesthetic with steroids was seen over local anesthetic alone.

Intracranial hypertension is a well-known life-threatening complication of bacterial meningitis. Investigations on decompressive craniectomy after failure of conservative management are scarce, but this surgical treatment should be considered and performed expeditiously, as it lowers the intracranial pressure and improves brain tissue oxygenation. Early cranioplasty can further aid the rehabilitation. ⋯ This unique report shows that decompressive craniotomy with duroplasty may be a crucial therapeutic approach in bacterial meningitis with refractory increased intracranial pressure and brainstem compression. Early cranioplasty with a patient-specific implant allowed the early and full reintegration of the patient.

Ruptured spinal arteriovenous malformation: Presenting as stunned myocardium and neurogenic shock.
Neurogenic pulmonary edema (NPE) is a clinical syndrome usually defined as an acute pulmonary edema occurring shortly after a central neurologic insult. NPE was identified 100 years ago, but it is still underappreciated in the clinical setup. NPE usually appears within minutes to hours after the injury. It has a high mortality rate if not recognized early and treated appropriately. Similarly, neurogenic shock is a known complication of spinal cord injury reported incidence is more than 20% in isolated upper cervical spinal injury. But NPE is rare to occur, and stunned myocardium (SM) is not reported in spinal arteriovenous malformation (AVM) rupture. SM is a reversible cardiomyopathy resulting in transient left ventricular dysfunction which has been described to occur in the setting of catecholamine release during situations of physiologic stress. We report a case of high spinal AVM rupture presenting as SM, NPE, and neurogenic shock. ⋯ Spinal AVM rupture can present as neurogenic shock, stunned myocardium, and pulmonary edema. Early recognition of AVM rupture and prompt surgical intervention, as well as aggressive treatment of shock, may enhance recovery and decrease the long-term morbidity.
