Arachnoid webs are rare intradural lesions that can cause direct spinal cord compression or alteration of the cerebrospinal fluid flow with syringomyelia. Surgery has been historically performed through wide-open laminectomies. The aim of this study is to prove the feasibility of minimally invasive techniques for the excision of arachnoid webs. ⋯ For symptomatic arachnoid webs, surgery remains the only definitive treatment. In expert hands, the excision of arachnoid webs can be achieved with tubular retractors and minimally invasive techniques.

Perforating arteries are thin and long vessels which originate from the main cerebral arteries. Subarachnoidal hemorrhage from a perforator aneurysm is rare. ⋯ MR imaging, however, demonstrated occlusion of the aneurysm secondary to thrombosis. Surgery was performed to remove the associated hematoma, and histopathological examination verified intraaneurysmal thrombosis.

Spinal extradural arachnoid cysts are relatively uncommon. Rarely, large cysts presented with spinal cord compression requiring surgical intervention. ⋯ This case illustrates the principles of timely surgical intervention after advanced diagnostic imaging and electrodiagnostic testing to improve neurologic function and minimize complications.

To investigate the association between ultraearly hematoma growth (uHG) and clinical outcome in patients with spontaneous intracerebral hemorrhage (sICH) receiving hematoma evacuation. ⋯ uHG is a helpful predictor of unfavorable outcome in sICH patients treated with hematoma evacuation. The optimal cutoff of uHG to assist in predicting unfavorable outcome in sICH patients receiving hematoma evacuation is 8.7mL/h.
