Diagnosis of spontaneous intracranial hypotension (SIH) may be delayed due to nonspecific symptoms and variable imaging findings. Cases of hyperostosis in children who are overshunted, a process that may be physiologically analogous to adults with SIH, have been reported by others and observed in our practice. The purpose of this retrospective study was to assess the frequency and pattern of calvarial hyperostosis in patients with SIH. ⋯ Diffuse calvarial hyperostosis, particularly the concentrically layered form that we term "layer cake skull," is a relatively common imaging feature in patients with SIH. In the appropriate clinical context, this finding will allow the possibility of SIH to be raised based on computed tomography imaging, which is otherwise of limited utility in the initial diagnosis of this condition.

The treatment of patients with ≥11 brain metastases (BMs) with stereotactic radiosurgery (SRS) alone has yet to be established. The aim of this study was to compare results of SRS alone in patients with 5-10 BMs versus 11-20 BMs. ⋯ Carefully selected patients with 11-20 BMs are not unfavorable candidates for SRS alone.

Hydatid disease most frequently occurs in the liver. This article presents a case of spinal cord compression caused by vertebral hydatidosis with typical imaging characteristics and pathologic findings, which is rarely involved in the hydatidosis. The patient was successfully treated with surgical excision combined with antiparasitic therapy.

Continuous Interrupted Double Throw Suturing Method: A novel suturing technique for Extracranial-Intracranial Bypass.
Despite failure of the EC/IC Bypass Study Group to demonstrate effectiveness in minimizing future stroke events, superior temporal artery-medial cerebral artery (STA-MCA) bypass remains an essential treatment for complex giant intracranial aneurysms, tumors, moyamoya disease with ischemia, and atherosclerotic steno-occlusive disease with hemodynamic cerebrovascular insufficiency. The objective of this report is to describe a novel suturing technique for STA-MCA bypass that helps reduce donor-recipient anastomosis time, allowing for a well-organized systematic workflow. ⋯ We describe a novel technique for interrupted STA-MCA bypass suturing that adds efficiency, safety, organization, and operative ease compared with the conventional method of interrupted vessel suturing.

The principles of endovascular treatment of bilateral cavernous sinus dural arteriovenous fistula (CS-dAVF) are not well established because of the complexity in the number of fistula tracts and their behavior, which seems to be more aggressive. We aimed to determine an efficient technique for endovascular treatment of bilateral CS-dAVF and the associated factors to achieve good clinical and angiographic outcomes. ⋯ Dangerous venous drainage tends to increase in bilateral CS-dAVF. Retrograde ipsilateral inferior petrosal sinus catheterization using coil embolization and sequencing the embolization are the major concerns for treatment.
