Comparative Study
Comparison of Satellite Sign and Island Sign in Predicting Hematoma Growth and Poor Outcome in Patients with Primary Intracerebral Hemorrhage.
Satellite sign (SS) and island sign (IS) are novel noncontrast computed tomography (CT) predictors of hematoma growth. The aim of this study was to compare diagnostic performance of IS and SS in predicting hematoma growth and functional outcome in patients with intracerebral hemorrhage (ICH). ⋯ IS seems to be an optimal shape irregularity imaging marker for predicting hematoma growth and functional outcome in patients with ICH.

Review Case Reports
A rare case of the postoperative symptomatic cyst formation after the resection of a large convexity meningioma.
Symptomatic cyst formation after brain tumor resection is a rare complication of the early postoperative phase. We describe a complicated case of postoperative symptomatic cyst formation after gross total removal of a convexity meningioma. ⋯ Even though formation of symptomatic cystic lesions after brain tumor resection is rare, neurosurgeons should be aware of such early postoperative complications and their management strategies.

Multicenter Study
Prospective registry of embolization of intracranial aneurysms using HydroSoft coils: Results of the Japanese HydroSoft Registry.
The effect of HydroSoft coils on the prevention of recanalization and thrombosis after embolization is unclear. We herein report the results of the single-armed prospective Japanese HydroSoft Registry. ⋯ The safety and prevention of recanalization 1 year after the treatment appeared acceptable. The high volume embolization ratio associated with HydroSoft coils could induce progression of thrombosis for aneurysms characterized by NR and BF during the follow-up period.

Checkpoint immunotherapy (CIT) is an emerging and exciting treatment modality for the treatment of cancer. Much excitement has ensued in the potential of CIT to revolutionize the treatment and prognosis of brain metastases. ⋯ However, several questions have arisen, in particular, the timing at which SRS and CIT should be administered relative to each other. We reviewed the reported data and attempted to offer a potential answer to this question.

Review Case Reports
Pre-truncal Non-Aneurysmal Subarachnoid Hemorrhage with Underlying Hemophilia C.
Pretruncal nonaneurysmal subarachnoid hemorrhage (PNSAH) accounts for 15%-12% of all case of subarachnoid hemorrhage. Its precise etiology is not yet established. Multiple theories and risk factors have been investigated to address the possible cause of this type of hemorrhage including basilar tip dissecting aneurysms, high spinal arteriovenous fistula, venous stenosis/hypertension or venous bleeding. Hereditary coagulopathies and hemophilias have rarely been reported in the literature as a potential cause of PNSAH. ⋯ Detailed medical history and physical examination of patients with PNSAH may lead to further hematologic evaluation for this group of patients, as in this case, and may reveal more cases of mild coagulopathy that require treatment.
