Multicenter Study
Increased peri-operative crystalloid transfusion is associated with better outcomes after spontaneous hypertensive putamen hemorrhage: A retrospective study.
The appropriate amount of transfused fluids, and which types of fluids should be transfused during the peri-operative period, is a matter of controversy among neurosurgeons. Thus, a retrospective study was conducted to assess whether crystalloid transfusion is associated with better outcomes after spontaneous hypertensive putamen hemorrhage (HPH). ⋯ Increased perioperative crystalloid transfusion was independently associated with better outcome across a spectrum of surgical risk profiles after spontaneous HPH.

Review Case Reports
Small unruptured intracranial aneurysm (≤5mm) associated with epilepsy: report of 2 cases and literature review.
Owing to the continuing improvements in imaging technology, an increasing number of epileptogenic small (≤5 mm) unruptured intracranial aneurysms (sUIAs) are being diagnosed. However, these sUIAs have not been systematically described and reviewed until now. ⋯ The seizures caused by sUIAs are most likely related to subclinical hemorrhages. Angiography may be helpful in identifying seizures associated with sUIA in patients with normal conventional MRI findings. For epileptogenic sUIA with normal preoperative MRI, clipping without damaging the surrounding brain tissue may be sufficient to resolve this complex issue.

Review Case Reports
Rathke cleft cyst with entirely ossified cyst wall and partially solid content in the cyst: a case report and literature review.
In Rathke cleft cysts (RCCs), inflammation by the cyst contents infrequently spreads to the surrounding structures. Calcification, which is regarded as a result of chronic inflammation of the cyst wall, can rarely be found in RCCs. Moreover, ossification is extremely rare. ⋯ Persistent, long-term inflammation induced by the RCC content, mucin-containing fluid, and several phases of hemorrhage presumably promoted the formation of mature bone on the cyst wall and of the elastically solid nodule within the cyst.

Ruptured middle cerebral artery (MCA) aneurysms usually lead to subarachnoid hemorrhage (SAH), and several cases have shown concomitant intrasylvian or intracerebral hematomas. The objective of this study was to compare the clinical and radiographic characteristics with their different outcomes. ⋯ In our series, the prognosis of patients with ICH was worse than that of patients with ISH. Early discrimination of these 2 types of hematoma helps to predict future outcome; an angle (between the pointing direction of aneurysm and the MCA trunk) between 109.0°and 216.0° is associated with ISH, whereas aneurysm with an angle beyond this range suggests ICH.

Review Case Reports
Surgical treatment of metallic foreign body embolization in the middle cerebral artery: case report and literature review.
Intracranial artery embolization cases caused by foreign bodies are extremely rare clinically. Twenty-four cases in total have been reported in the literature; among them, 20 cases were caused by firearms, and only 4 cases originated from nonfirearm injuries in daily life. ⋯ Based on our experience, as well as on the premise that the surgical technique is mature and the medical facilities are well equipped, such patients should undergo embolectomy as soon as possible to avoid severe cerebral hemorrhage due to mechanical injury and vascular wall corrosion.
