Owing to recent advances in medical optical technology, a high-definition (4K) three-dimensional (3D) exoscope has been developed as an alternative tool to using conventional microscopes for microscopic surgery, and its efficacy for neurosurgery has been reported. We report a case who underwent simultaneous surgery aiming for en bloc resection of an anterior skull base malignancy with concurrent exoscopic transcranial and endoscopic endonasal approaches using a 4K 3D exoscope. The patient was a 76-year-old woman who underwent en bloc resection for an anterior skull base olfactory neuroblastoma 13 years ago. After confirming the recurrence of progressive olfactory neuroblastoma, tumor resection was again decided to be performed. As with the first procedure, surgery was performed in an en bloc manner, using both transcranial and endonasal approaches. Exoscope provided enough space above the surgical field to allow us to perform transcranial and endonasal surgeries simultaneously. Moreover, the surgeons could maintain a comfortable posture throughout the procedure, and total tumor removal was successfully achieved without any abnormal event. To our knowledge, this is the first report of the introduction of an exoscope aiming for en bloc resection of an anterior skull base malignancy while performing simultaneous surgery with both transcranial and endonasal approaches. We believe that the more cases are accumulated, the more efficacy of a 4K 3D exoscope will be elucidated.

The current study aims to evaluate the incidence and results of aneurysmal subarachnoid hemorrhage (aSAH) throughout Kobe City. Based on a multicenter retrospective registry-based descriptive trial involving all 13 primary stroke centers in Kobe City, patients with aSAH treated between October 2017 and September 2019 were studied. A total of 334 patients were included, with an estimated age-adjusted incidence of 11.12 per 100,000 person-years. Curative treatment was given to 94% of patients, with endovascular treatment (51%) preferred over surgical treatment (43%). Of the patients, 12% were treated by shunt surgery for sequential hydrocephalus with a worse outcome at 30 days or discharge (14% vs. 46%, odds ratio (OR): 0.19, 95% confidence interval (CI): 0.088-0.39, p-value <0.001). As for vasospasm and delayed cerebral ischemia, most patients were given intravenous fasudil infusion (73%), with endovascular treatment for vasospasm in 24 cases (7.2%). The fasudil group had more good outcomes (42% vs. 30%, OR: 1.64, 95% CI: 0.95-2.87, p-value = 0.075) and significantly less death (3.3% vs. 35%, OR: 0.064, 95% CI: 0.024-0.15, p-value <0.001) at 30 days or discharge. Mortality rose from 12% at 30 days or discharge to 17% at 1 year, but neurological function distribution improved over time (modified Rankin Scale 0-2 was 39% at 30 days or discharge, 53% at 60 days, and 63% at 1 year). Our retrospective registered trial presented various statistics on aSAH, summarizing the current treatment status and prognosis.

There has been a noted increase in the incidence of intracranial aspergillosis; this is often attributed to the wider use of antibiotics, corticosteroids, and immunosuppressants. Fungal cerebral aneurysms due to aspergillosis after neurosurgery remain extremely rare; in fact, only seven cases have been reported in the literature. In this study, we present a patient with an Aspergillus aneurysm that elicited subarachnoid hemorrhage after endoscopic endonasal surgery (EES) for craniopharyngioma. A 70-year-old woman with recurrent craniopharyngioma and steroid treatment underwent uneventful EES. On the 5th postoperative day, she suffered subarachnoid hemorrhage. As per her computed tomography angiography findings, an aneurysm was detected on the left internal carotid artery (ICA). Subsequent digital subtraction angiography showed occlusion of the ICA and an irregularly shaped wall. The diagnosis was pseudoaneurysm. We then performed craniotomy to place a left high-flow bypass and to trap the pseudoaneurysm. Despite continuous intensive care, she died on the 25th postoperative day of a huge, left cerebral infarct. The final diagnosis was made at autopsy; it revealed destruction of the ICA and Aspergillus invasion of the vessel wall, confirming the presence of a true fungal aneurysm. Perioperatively, patients with potential immunosuppression must be carefully managed. Advanced age is a risk factor. As surgery via the paranasal sinuses raises the risk for aspergillosis, fungal infection must be ruled out in patients whose postoperative course is deemed concerning.
