There was a mean registration error distance of 3.36 mm (SD 2.82 mm) between targets. The longitudinal extent and severity of the disease through the target segment could be easily evaluated after co-registration.

Semiautomatic tracking and co-registration of angiography and IVUS is a new technology and has the potential to increase the use of IVUS in carotid disease and to proivde the opportunity to optimize procedural outcomes.

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.

The authors present a case of spinal IgG4-HP with a systematic review of the literature according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Relevant studies (up to April 2020) that reported patients with spinal IgG4-HP, based on the criteria of Japan College of Rheumatology, were identified from the PubMed and Cochrane Library databases.

This systematic review identified 33 patients, including the present case, of whom 21 were male and 12 were female. The mean value of age was 51.2 (±12.6) years. Eight patients had systemic involvement. In addition, among 33 patients, 13 patients had an elevated serum IgG4. Surgery was performed in 31 patients. Steroid therapy alone and steroid therapy with immunosuppressants were effective in 94% and 100% of the cases, respectression. Long-term follow-up is necessary for patients with spinal IgG4-HP.

Angiomatoid fibrous histiocytoma (AFH) is a rare, fibrohistiocytic, soft-tissue neoplasm. Intracranial AFH is extremely rare. Here we present 2 pediatric cases of intracranial AFH and perform a literature review on this disease entity.

We present 2 cases. The first case is a 10-year-old boy who presented with seizures and hemiparesis. The second case is an 11-year-old girl who presented with 2-year history of seizures. Radiologic images demonstrated right frontal lesions in both patients. Complete surgical resection was achieved. PGE2 Histopathological findings established the diagnosis of intracranial AFH confirmed with fluorescence in situ hybridization and reverse transcriptase polymerase chain reaction testing that demonstrated EWSR1 gene rearrangement in both cases.

Twenty-two cases of intracranial AFH have been previously documented, with the majority of lesions located in the frontal lobe. Most cases occurred in adolescents and young adults, with a slight female predilection. Headaches and seizures constituted the most common clinical presentation. Complete surgical resection remains the standard of care in the management of this pathology.

Hemorrhagic vascular lesions in the posterior cerebral circulation such as ruptured aneurysms and dissections can be challenging to treat. Flow diversion has become an important off-label option, but few studies have analyzed the safety of these devices in this setting. Using an international, multicenter cohort, we reviewed posterior circulation subarachnoid hemorrhage (SAH) patients treated with the Pipeline Embolization Device (PED) in the acute setting and assessed the incidence of Takotsubo cardiomyopathy (TCM).

Eleven neurovascular centers were queried to identify cases of posterior circulation aneurysms or dissections treated with the PED in the acute setting of SAH. Among those, 5 centers had cases that matched the inclusion criteria. The following variables were evaluated demographics, the location and morphology of the aneurysm, the clinical presentation, the specific form of treatment, complications including the development of TCM, antiplatelet medication regimen, and follow-up time.

A total of 23 patients were treated with PED after posterior circulation SAH, and 13% of these developed TCM. The lesions were the result of hemorrhagic intracranial dissection (8 patients), ruptured pseudoaneurysm (3), ruptured saccular aneurysm (7), blister aneurysm (4), and fusiform aneurysm (1). Ninety-one percent of patients had complete or near-complete aneurysm occlusion on follow-up imaging. Five patients died in the perioperative period; 16/18 survivors had a favorable outcome.

We describe an unexpectedly high incidence of TCM after the placement of PEDs in patients with posterior circulation SAH in our large case series. Further studies will be needed to elucidate possible causes.

For most of the international community outside the epicenter, coronavirus disease 2019 (COVID-19) containment is normalizing, and daily medical practice runs parallel to preventing and treating COVID-19. This experience of simultaneously conducting emergent surgery and infection control for COVID-19 disease is useful outside the epicenter during the pandemic.

In this single-center retrospective observational study, we enrolled patients with subarachnoid hemorrhage (SAH) who were emergently admitted from January 23 to April 8, 2020. Based on the COVID-19 triage, patients with SAH were divided into 3 categories positive, negative, and under investigation. During 77 days, 90 patients with SAH were admitted at the center. The median age was 55 years (range, 18-80 years) and 40 patients (44.4%) were male. None was positive, 42 patients were negative, and 48 patients were under investigation for COVID-19 before surgery. During the same period, 9 patients were diagnosed with COVID-19 without nosocomial infection.
